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.
