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.
