Plastic Road Barriers and their Advantages

Long term construction projects especially out on the road often require plastic road barriers. Our in-house designed and built interlocking plastic road barriers are perfect for road closures, low speed zones and construction projects. 

Plastic road barriers have several great advantages over traditional barrier solutions. Metal and concrete barriers are not only extremely heavy but also expensive. Our lightweight plastics design provides the same function for a fraction of the price.

Our lightweight barriers can be easily manipulated into position and then filled with water to stay there. Each barrier can interlock with its neighbours serving as a pivot point. Therefore, in the event of a crash the impacted barrier is prevented from toppling and the entire barrier chain absorbs the impact.

Ourn genius interlocking design does not require any pins or cables, as every barrier is designed with a male and female end. Allowing for simple and fast interlocking to form a barricade without extra supplies. 

Unlike traditional counterparts, plastic road barriers can come in a wide variety of colours. Polyethylene plastic is able to be dyed any colour and treated to resist fading in the harsh New Zealand sun. Keeping your barriers highly visible throughout their lifespan.

Orange is a commonly chosen colour for use in road works and construction. However, other colours like white are useful as pedestrian barriers. The lack of visibility can help steer crowds from areas of restricted access during events. 

Once your plastic road barriers finally come to the end of their life, they are fully recyclable. Keeping the plastic out of our landfills.

If you are looking for plastic road barriers for your construction project or event. Then call us at 0800 768 284 or contact us online. We are happy to offer you advice and answer your questions to find the right solution for you.

Stormwater Detention Tanks, What You Should Know

If your Auckland property is experiencing flooding then an underground detention tank is a simple yet ingenious solution. Auckland is particularly susceptible to flooding due to the sheer amount of development. Our New Zealand made detention stormwater tanks come in a variety of sizes to suit your properties needs and protect your Auckland property against stormwater flooding.

How does new development cause flooding?

This is a good question. How does construction or development cause an area to flood that previously never had? During a storm, water seeps into the ground and the groundwater table. If this cannot happen the rain will become surface runoff, making its way to a local river, stream or other natural body of water. 

New developments can impede nature’s solution for flooding. Stormwater cannot be absorbed by concrete, homes and other buildings and so becomes surface runoff. If the water cannot find its way into the earth or a local body of water then it is up to the stormwater system to remove this excess water. If the stormwater system is not able to effectively remove the surface runoff, flooding will occur.

How does a detention tank work?

If stormwater cannot escape through the stormwater drain a detention tank can act as a buffer. By storing rainwater in a large tank, either above or below ground, water can accumulate in a controlled environment. Meaning the flooding is moved into a space where it cannot damage buildings and developments.

Once the water is in the detention tank, it is released into the stormwater drain or other runoff with a restricted flow. The slow-release prevents further strain on stormwater systems and decreases the chance of flooding.

What kind of detention tanks do we offer?

Here at rotational plastics, we offer a large selection of New Zealand designed and produced detention stormwater tanks. We offer both above and below ground detention tanks in a variety of sizes to suit the needs of your property.

In a recent Sydney survey, 90% of detention tanks were blocked or had been disabled. Debris can cause blockages, preventing water from entering or exiting the tank. Our tanks are designed with a double filtration system that eliminates this issue. Similar to a swimming pool, the filters can be easily removed to clean out debris, extending the life of your detention tank.

If your Auckland property requires a stormwater detention tank then give us a call at 0800 768 284 or contact us online. We are happy to help you choose the right detention tank for your property.

Custom Plastic Moulding Cost

Custom plastic moulding could make your innovative idea for a product a reality. Often people think producing a product out of plastic is farfetched, and that a large factory overseas is needed. This is not the case, as custom rotational plastic moulding can make it straightforward and cost-effective at any production scale.

When looking to create a plastic product one of the first things considered is the custom plastic moulding cost. Different plastic moulding solutions offer unique advantages and savings. Rotational moulding offers various advantages both in design, production, and cost when creating a custom plastic mould.

Cost considerations

What exactly are some of the costs of developing a custom plastic mould?


All plastic products are made by filling a mould that is in the shape of what you want to make. Some processes like injection moulding use high pressure to force melted plastic into place. Here at Rotational Plastics, we use, you guessed it, a process called rotational plastic moulding, also known as rotomoulding.

Rotational moulding is a low-pressure process which means unlike other processes, weaker and cheaper materials, like aluminium can be used to create custom plastic moulds. Since the moulds are not under pressure, they do not require the same tolerances.

Because tooling can account for upwards of 70% of the initial start-up cost when creating a new custom plastic mould an expensive mould could make or break your dream. Rotational Plastics steel miller can create cheap moulds from steel but can offer aluminium moulds when required.


If you have an idea for a product but do not know how to convert that to a design for a custom plastic mould, the team the rotational plastics is happy to use their industry expertise to assist you and ensure your vision comes true.

Realizing your idea may come with some hurdles, but more than likely our team has encountered them all. Engineering a product to be suited to rotational plastic moulding is an art form. Requiring intricate knowledge of what is and is not possible. Due to the nature of rotational plastic moulding, certain designs may be impossible to produce. The team at Rotational plastics will help you through the design process to ensure these are avoided early in development.


Generally, the design, testing and mould tooling is almost all the cost involved in setting up a custom plastic mould. When it comes to producing your plastic product, the cost pales in comparison.

So how much can you expect to pay for custom plastic mould?

The cost of a custom rotational mould is not as straightforward as one might think. Depending on size, the complexity of design, to the material used for the mould, the price can range from as low as $3,000 to $30,000. Because design and tooling are where the money is invested, having a team as talented and professional as the one here at Rotational Plastic is key. If you have an idea for a custom plastic mould, give us a call at 0800 768 284 or contact us here. The Rotational Plastics team have developed a process to lead you to your goal and is eager to help your project succeed.

The client was left impressed by the selection of sizes and shapes of our commercial plastic storage solutions. If you are looking to get your business organised give us a call at 0800 768 284 or browse our selection online.

Why Hospitals Need Sterile Equipment

Hospitals are where people run to when they have an ailment, an injury, or need an operation or procedure done. Patients tend to be weaker than regular people who are healthy. They need a special environment where they can be treated for their illness or disease without succumbing to further infections caused by germs or bacteria.

The goal is to make patients better, not worsen their condition. Plus, doctors, nurses, and other hospital personnel need to protect themselves from diseases so they can help patients to the best of their abilities, no less. This is why every single equipment in any given hospital must be sterile and clean.

Why You Need Sterile Hospital Equipment

From the operating room equipment down to the trash bins, hospital equipment must be sterile and sanitized in order to avoid making a patient’s condition from getting worse or transmitting diseases from one patient to another. Every tool, every stand, every bed, every instrument must be sterile. Just being clean simply won’t do.

Retention vs. Detention Tank: Which One Do I Need?

We get asked this question quite often: what is the difference between a retention tank and a detention tank?

Both tanks are used to collect rainwater or stormwater. However, a retention tank is designed to keep the water for use at a later date, while a detention tank eventually drains the water shortly after it is collected.

Rainwater vs. Stormwater

For the purpose of clarity, it is worth distinguishing between rainwater and stormwater.

Rainwater quite simply refers to the rain that falls on the roof, which is often harvested into a storage tank before it gets in contact with the ground. On the other hand, stormwater refers to rainwater falling on roofs down to the gutters and downpipes or runoff from ground surface areas such as driveways, gardens, lawns, footpaths and roads. Naturally, rainwater is of much higher quality since it contains fewer contaminants (e.g. soil, debris, chemical fertilisers, oil residues, etc.).

Harvesting rainwater can help reduce your water bills, as you are essentially utilising a free, renewable resource. A water retention tank would be a good investment for this particular purpose.

Water Retention Tanks

A typical retention tank is designed to harvest both rainwater and/or stormwater, and retain the water rather than simply draining it off. The harvested rainwater can then be used for many purposes such as:

  • irrigating your garden
  • flushing toilets
  • topping up your swimming pool without using mains water
  • washing your cars and driveway
  • washing clothes
  • drinking (if the water system is properly maintained and water is treated)

Stormwater is generally unsafe for drinking, but it can often be utilised for low-risk purposes such as toilet flushing and garden watering. If treated, stormwater can even be used for filling swimming pools.

Investing in retention tanks makes sense, even more so if you’re in a rural area where there is no access to reticulated water supply or where there is a greater need for water for agricultural use.

Stormwater Detention Tanks

Detention tanks also collect rainwater and/or stormwater, but they are typically utilised as part of an effective stormwater system for new homes. Local councils require new homes to have an effective drainage system, which would help in managing the flow of runoff entering bodies of water.

As the name suggests, a water detention tank is designed to “detain” water, that is, to say, it holds the water for a limited period only. The tank is intended to drain the water and remain empty except during a rainfall event and for a short period thereafter.

Stormwater detention tanks have a large inlet pipe and a smaller outlet, which prevent sudden surges of runoff by averaging the out peak flow. This takes some pressure off our ageing stormwater network and consequently prevents flooding.

Why should you use a detention tank?

Its biggest help is assisting your local area’s stormwater drainage facilities to drain manageable loads of water runoff during heavy downpours. Increasing the capacity of existing drainage facilities to keep up with increased stormwater flows has its constraints (i.e. cost and space), which is why many councils have passed on to new home owners some of the responsibility for their stormwater runoff.

To put simply, whether you need a stormwater detention tank and to what extent you need it depends on your local council. How big the detention tank basically depends upon a number of things, such as the size of your property, the building structures within your property, and the surface area of your roof. Your local builder should be able to tell you the right size you need, and your local council should have some table or equation for this as well.

A detention tank can be a standalone facility, or it can be made to work double as a retention/detention system. It can also be used in addition to a rainwater tank which, in heavy downpours, will fill up quickly. The addition of a retention tank, in this case, keeps space available for more water to be detained in the event of prolonged or consecutive rainfall. This solution is preferable as it maximises your rainwater/stormwater collection. This type of system may need to be designed for your property and submitted for council approval.

Because stormwater often carries small debris, blockage often occurs which makes the detention tank ineffective. We at Rotational Plastics have designed our detention tanks with a double-filter system, which features one filter at the inlet point to arrest large debris and another filter by the tank outlet to catch smaller particles.

Materials used for water tanks

Rainwater/stormwater tanks come in different sizes, shapes and materials. Below are some of the most commonly used materials for retention and detention tanks.

  • Galvanised steel. Steel water tanks have a zinc coating that protects it from corrosion. They are built with capacities from about 30,000 litres to a million litres, making them a suitable solution for large storage requirements. Over time, the zinc coating may leak into the water which results in rusting. This problem is often overcome by adding liners made of food-grade polyethylene, although it is expensive to fabricate and is vulnerable to wear over time.
  • Fiberglass. The quality of fibreglass tanks depend on the maker. In general, they are rigid but light and thin, making them prone to cracking. This type of material needs a food-grade coating to make it safe for storing potable water.
  • Polyethylene. The most popular water tank material by far, polyethylene is exceptionally strong and durable but relatively lightweight. These properties make polyethylene water tanks easy to install and cost effective. Polyethylene is a high-quality plastic that is recyclable and reusable, making it an environment-friendly material. It is a food-grade plastic so it’s non-corrosive and does not need a liner, which tends to disintegrate over time. The flexibility of plastic allows the tank to be moulded into various shapes and dimensions. Poly tanks can be made in storage capacities of up to about 50,000 litres.

Roading Plastics: Benefits of Plastic Road Barriers

Plastic offers some of the best alternatives to traditional products. One great example is “roading plastics”, such as plastic road barriers and pedestrian barriers, which solve most of the issues with their concrete or metal counterpart.

Road safety barriers serve many purposes. They help reduce traffic congestion in highways and increase safety on the road. And while traditional road barriers perform well, they are particularly problematic when it comes to ease of use and maintenance.

This is where plastic barriers enter. And here’s why here’s why it just makes sense.


Plastic road barriers are hollow, which is why they are much lighter in weight compared to metal and concrete ones. They are typically filled with water which can be conveniently drained though a drain plug at the bottom. Their lightweight property lends them portability, which reduces transportation costs by a huge fraction. Because they are light and easy to deploy, more units can be loaded in a vehicle and less manpower is required to install them. This eliminates the need to hire a forklift to move them between events or work sites.


Plastic road barriers are moulded into single block units, which mean there are no moving parts that may loosen up or break over time. There are no metal hinges that may rust, either. Each unit is designed to interlock to create a continuous wall or barricade without the use of pins or cables. Our roading plastics are made from high-quality polyethylene which is rotationally moulded to offer the best durability. They are moulded to a minimum thickness of 8mm so they don’t crack or break under normal use. These barriers can last over 40 years.


The male/female ends of each barricade, which allow interlocking of multiple units, serve as a pivot point that allows a variety in the angles the barriers are set up. This allows your barricade to swing if impacted, instead of breaking or toppling.

And speaking of versatility, plastic road barriers can accommodate add-on features to suit various applications, including banners, warning signs, safety lights and signage for increased visibility.


The beauty of polyethylene plastic is it comes in a wide array of attractive colours, which make them more visible from a distance. In roading applications, visibility is an essential factor for the effectiveness of safety barriers. During the manufacturing process, an ultraviolet light inhibitor is added to the plastic to keep the colours from fading even under constant exposure to sunlight.

Aside from colour, plastic barriers can also be moulded into any shape or size. So if you have specifications other than the standard, we can help you design and manufacture custom barriers suitable for your intended application. These can even be branded with your company name or logo for marketing purposes or simply to prevent theft in job sites.

Environment friendly

Not all plastic is bad for the environment. In fact, polyethylene is 100% recyclable. So when your plastic road barriers no longer serve their purpose, they can be reprocessed into something else and will not end up in landfills.

All these properties make plastic barriers an ideal option for crowd and traffic control in highways, construction zones, car parks, ports, sporting events, shows, pedestrian walkways and many other situations.

That being said, not all plastic road barriers are created equal. Precision and the quality of construction are important to ensuring your barrier of choice will withstand even the harshest conditions.

We, at Rotational Plastics, are confident about the superior quality of our products. We work hard to provide tailored solutions to all budgets and needs.

Food Grade Pallets In New Zealand

Food safety is a huge concern in the food and beverage industry. Any business in the sector must ensure their food is safe for the end consumer and prevent contamination at any stage in the supply chain. Even a small case of contamination can cost dearly and result to legal liabilities.

Plastic food pallets offer a hygienic solution for ensuring the safety of products during export, shipment or internal warehousing.

Plastic vs. Wood

Are plastic pallets superior to wood pallets? The answer is a resounding yes. The great debate has already been settled, the use of plastic pallets is already a growing trend in the F&B industry. Here are some of the reasons why:

  • Resistance to moisture. Food-grade plastic pallets are non-porous. This means there are no hidden reserves that will hold moisture or fluids that harbour moulds or pathogens (such as Salmonella, Listeria and coli). Since there are no fibres in the material, fluids from raw foods such as meat can easily be cleaned and sanitised between loads. The non-porous surface also ensures no harsh chemical residue from cleaning agents will build up and get in contact with the food.

  • Does not require fumigation. Wood pallets often require fumigation or some sort of heat treatment to repel pests (such as the ambrosia beetle and the emerald ash borer) and fungus. Such treatments can make the pallets more susceptible to mould growth, and they sometimes use chemicals that are not considered food-safe. In fact, a well-documented case of Johnson & Johnson product recalls years ago was directly linked to chemical treatments applied to wood pallets, specifically, the toxic pesticide 2, 4, 6-tribomoanisole (TBA).

  • Resistance to heat. Heat resistance is one of the inherent properties of our plastic pallets, which lend them superior durability. Even in high heat or humidity, the pallets are guaranteed to perform well without breaking or warping.

  • Lightweight. Our pallets are designed to be hard at work yet easy to use. They provide the support and efficiency required in moving products through the supply chain, without adding to the bulk or weight. A standard 48” x 40” pallet can hold up to 2,800 pounds. As a result, using our food-grade plastic pallets can help lower your shipping costs by adding less weight to shipments and speeding up the delivery of goods.

  • Long operational life. Moisture and fluids are bad news for wood pallets. Once the pallets get soaked, they become hard to clean and dry completely. Over time, they become brittle and prone to contamination. Plastic eliminates this problem, so they can be used over and over for a relatively longer operational life. Even better, old pallets can be recycled into other products. This reduces your operational expenses and waste.

  • Keeps products in good condition. Splinters or protruding nails on wood pallets can bruise or puncture food products, making contamination more likely to occur. But this is never the case with plastic pallets. These pallets are made with high-quality plastic that is moulded to produce a solid block construction with no nails or screws necessary.

  • Environmentally friendly. Although plastics generally have a bad rap, plastic pallets are particularly more eco-friendly compared to their wooden counterparts. They can be ground and re-used to make new pallets.

Rotational Plastics have a range of food-grade pallets that provide both sanitary performance and exceptional value. Our pallets come in various sizes, colours and configurations to suit all possible kinds of applications. For instance, some types have ribbing or lip edges for better stability of the products during transit.

Given the safety, cleanliness and reliability of plastic pallets, more and more food companies are transitioning to using them for their shipping and warehousing activities.

Plastic Pallets For Supply Chain Management

One of the biggest challenges for any form of business is optimising efficiency in the supply chain. It’s not enough to simply produce quality products if you can’t get them to the shelves in the best condition. Efficiency means safe handling and transporting items conveniently at an affordable cost.

If you’re still using wood pallets, it’s time to transition to their plastic counterpart. The benefits of using plastic pallets are just too good to ignore:

  • Lightweight. Weigh is a major concern during loading, offloading and shipping products. It adds extra costs and requires more effort to handle. Since plastic pallets are much lighter than wood pallets, they can help you save on shipping costs and make handling much more convenient.
  • Extremely durable. Wood pallets typically last for 3 to 5 years, but the lifespan of plastic pallets is up to 10 years. Moreover, plastic pallets can withstand shock and support more weight with minimal wear and tear. With proper use, they will neither break nor splinter. If you are operating a closed-loop system where you use the pallets over and over, plastic ones are best to use.
  • Safe to handle. Plastic pallets have no moveable parts because they are injection moulded or thermoformed into one single block construction. This means there is no risk of injuries from rusty nails, splinters, sharp edges or protruding fasteners. Knowing safety is guaranteed, your staff will handle products with confidence and efficiency.
  • Hygienic and easy to clean. Plastic pallets don’t absorb liquids or drippings from raw meat. Consequently, they do not attract pests or harbour moulds and harmful pathogens. All they need to be clean is a quick wash, which is why they are a perfect hygienic solution in the pharmaceutical and food and beverage industries. Our plastic pallets are specifically made from food-grade material to maintain hygiene at all times.
  • Dimensionally stable. This feature lends plastic pallets superior performance. When used for the recommended load capacity, the pallets will retain its original dimensions, i.e. width, length, height, block width, entry width and under clearance.
  • Weather resistant. Exposure to rain or high humidity won’t damage our UV-stable plastic pallets. Even corrosion, shock, stress and weak acids will not affect them. Thus, they are a must-have all-weather solution in the supply chain. They can also withstand low temperatures in freezers or chillers.
  • Branding. Need another platform for marketing your brand? Plastic pallets can be customised for any marketing purpose. You can stamp your brand on display pallets or choose a colour that identifies your business, to increase awareness. Moulding plastic pallets is a versatile process that offers unlimited possibilities. In addition to branding, the pallets can also be numbered or serial coded to make inventory more efficient.
  • Space saving. As well as weight, space is also a key variable in determining shipping costs. Plastic pallets can be stackable, rackable or nestable. This feature allows you to save space where possible, particularly during return trips.
  • Environmentally friendly. Consumers love brands that are environmentally conscious. By adopting plastic pallets, you’ll be marking yourself as an eco-friendly business. There are a number of reasons why. First, they save trees which are an important natural resource. Second, unlike their wooden counterpart, plastic pallets don’t need fumigation or heat treatment. Such treatments use toxic chemicals that make the pallets unsafe for food handling and contribute to environmental pollution. Third, plastic pallets are 100% recyclable. Old ones can be broken down and moulded into new ones.

Plastic pallet design

Versatility is one of key features of plastic pallets, as they can be moulded into unique designs to match the needs of a business.

Below are some of the most commonly used types:

  1. Stackable pallets – The bottom section of these pallets is designed such that multiple pallets can be stacked without comprising stability – with or without products.
  2. Rackable pallets – These are most dependable for managing heavy loads. They have either runner or picture frame configuration for enhanced strength. These pallets are designed to fit on racks seamlessly, which helps to save more space on the floor.
  3. Nestable pallets – Best to use if you need to maximise space. These pallets have “legs” that go into each other when stacked, allowing easy transport especially during the return trip.
  4. Drum pallets – Made specifically for transporting drums, these pallets have moulded recessed rings that may vary in size depending on the size of the container it’s used for. The recessed rings secure drums in place so they don’t slip or fall during shipping and storage.

Other features can be added to plastic pallets such as lip edges and spill control depending on applications. Speaking of such, plastic pallets may also be classified according to their use.

Below are some examples:

Product displays

You’ve probably seen this in supermarkets, groceries and retail stores. Plastic pallets can be branded and made in a range of colours or sizes to support promotional product displays. This allows an entire product display to be moved conveniently using a forklift.

Industrial export

Recycled plastic pallets are a cost-effective option for one-way shipping. Although they are not as durable as the ones made with 100% virgin polypropylene (PP) or low density polyethylene (LDPE) material, they are cheaper and nonetheless reliable.

Spill control

Plastic pallets used to transport liquid or beverage containers typically have slits or holes on the surface and a containment at the bottom for catching any leak or spillage. This way the leaks will not spill onto the floor or the shipping container, reducing the risk of slips and falls as well as the risk of contamination when transporting hazardous substances. Our range includes spill containment pallets from 50L splash pallets to 400L forklift-able pallets.

Plastic pallets can also be classified based on their capacity, i.e. heavy duty or medium duty. The heavy duty type is made using 100% virgin LDPE material, which makes them extremely durable for a long period of time. These are perfect for demanding applications such as in a closed-loop supply chain or in heavy industrial transport.

Reheating plastic makes the original material structurally weaker, which is why recycled plastic pallets are cheaper. Such as medium-duty pallets that are commonly used for internal warehousing purposes.

Whatever your business requires, you can get the best plastic pallets for the job from Rotational Plastics. We currently have 10 different pallet moulds including a couple of spill containment pallets. All out products are proudly manufacture in New Zealand using locally sourced materials.

Have You Experienced Flooding? You May Need A Detention Tank

If you are building a new home, there may be several requirements that you’ll need to meet. One of these requirements might be stormwater management, which will require the use of a detention tank. If you are experiencing flooding, a detention tank may also be your answer.

What are detention tanks?
Detention tanks are large tanks that are normally installed below the surface and used to suppress the effects of heavy rainfall, or stormwater. They work by temporarily storing the rainwater runoff during rainfall and slowly release the water through a small diameter orifice into the public storm water system. This reduces the peak flows of stormwater and reduced the chance of flooding due to an overloaded stormwater system.

Detention tanks are usually required in areas where storm water flooding risks are high. This is especially true in many areas in Auckland, with the current increase in population and housing. Generally speaking, if you are adding roof space by extending or building a new home in areas where stormwater systems have not been renewed, you will most likely require a detention tank.

Detention tanks can also be useful for managing stormwater onsite. This is most common used in combination with soak holes. This systems gives the ground enough time to soak excess water which prevents any surface or ground related flooding.

How big does my detention tank need to be?
In Auckland, a rule is based on several conditions such as the “storm of the 100 years” principle, which would be to allow for 100 liters per 1 square metre of roof surface area. Depending on detention requirement, the outlet orifice can range between 10mm-40mm. Some further information can be found regarding size of detention tank from Auckland Council here.

We at Rotational Plastics can help you get the detention tank you need for your home. See our large range of plastic detention tanks or call us on 0800 768 284 today!
