Centurion Barrier: The Water Filled & Road Barrier Experts

Centurion Barrier has established itself as the leading manufacturer and supplier of heavy duty barrier systems in Australia. With plans to expand into the Asian and Pacific markets, the success and expertise of Centurion Barrier is leading them to new and exciting places. Serving clients such as Royal Australian Navy, Queensland Rail Network, and Ford Civil Contracting, Centurion Barrier has built a reputation as a respected supplier of plastic water filled barriers for construction, delineation, and other uses.

Why Centurion?

Centurion’s barrier systems are specially designed to cope with Australia’s extreme and varied weather. From harsh sun to snow and ice, the barrier systems from Centurion are guaranteed to last through them all.

Since they deal exclusively in water filled plastic barriers, Centurion is an expert in what they do. Their products undergo rigorous testing to ensure that they will hold up well beyond the five year guarantee period offered on all of their products.

What Makes Centurion’s Barriers Different?

Centurion barriers are UV protected to avoid cracking and breaking due to sun exposure. While many people think of winter snow and ice as the harshest weather conditions, summer heat and UV rays can be just as damaging to plastic products that are constantly exposed to the elements. The UV protection that is part of Centurion’s plastic composition helps their barriers last for years out in the sunniest weather.

Not only are Centurion’s barriers designed to stand up to outdoor conditions, they are light and maneuverable when empty. This makes is easy to set up or move the barriers. Once they are filled with water, they are a solid, heavy delineation that can control any type of traffic.

Why Use Centurion Barrier?

Centurion Barrier has various products that are appropriate for many uses. Large, heavy barriers are ideal for delineating areas where vehicles need to be stopped from entering specific areas. These most robust barriers are often used in construction zones to direct traffic and avoid dangerous line crossing. Lighter barriers are appropriate for car parks or designating paths and areas for pedestrian traffic. Centurion even has barriers that are FAA approved for airport runway and traffic use.

Some places Centurion barriers are used include construction sites, go kart tracks, outdoor events, warehouses, driver training courses, and sporting events.

Centurion ships from the closest port for each customer’s convenience and shipping savings, and all products are guaranteed to last at least five years.

Benefits of Rotational Moulding on Polyethylene Barriers

In part 1 of this article we looked into the detrimental effects the elements can have on plastic, in particular in the context of hot and humid climates such as those of Australia , The Middle East  and the South Pacific. Now, we will examine the effects the weather has on water filled plastic barriers and the groundbreaking methods modern manufacturing processes provide to counteract them.

Barriers Exposed

When it comes to polyethylene barriers, exposure to the weather is bound to reduce their longevity and effectiveness. One of the effects it has is discoloring, which will defy the purpose of a barrier that is intentionally designed to be bright colored and serve as a visible barricade rerouting traffic and channelling or warding off pedestrians.

Moreover, plastic that becomes embrittled will quickly lose its mechanical properties, become prone to cracking and therefore fail to fulfil its function. When this happens, your water filled barriers are as good as useless and you will realise that you have been throwing your money down the drain.

Rotomoulding: A Groundbreaking Method

To counteract that, rotomoulded plastic provides such resilience against breakdown that is hard to match by injection molding or other conventional ways of fabricating plastic. Rotomoulding ensures a one-piece seamless construction that provides a product that is much more durable to the corrosive effects of outdoor environments and has excellent load-bearing properties.

Since rotomoulding involves the constant rotation of resin that coats all surfaces evenly, this results in a final product of uniform wall thickness that, as such, exhibits greater endurance to stress. What is more, during this process special stabilisers are added in the plastic known as UV inhibitors. As their name suggests, these make plastic more stable under heat and light or both combined, since they absorb and diffuse radiation in a way that does not harm the plastic.

Other Benefits of Rotomoulding

Apart from the corrosion resistance properties, rotomoulded plastics are known to have a plethora of other desirable attributes that gives them a competitive edge over other plastics. To mention just a few: they are lightweight, chemical resistant, economically and environmentally sustainable because there is no material wasted in their making. Plus, their production process is much more cost effective, which in turn dictates the price of the end product.

Being constantly on R&D mode, we, at Centurion Barrier Systems and Centurion Barriers Asia and Pacific know what makes barriers durable to the elements of these particular climates and employ the latest technological processes in producing them. All our barriers are manufactured by rotational moulding to the highest quality standards to ensure their longevity and the most competitive prices for the end user.

Moveable Barriers Offer Huge Savings & Benefits

Barriers manufactured by Centurion Barriers have been designed with safety and durability as our highest concern, but one of the top advantages we have over our competition is that our barriers save money–on manpower resources, on the time it requires for installation, and they save virtually tonnes in transportation costs.

Steel and concrete barriers require very large heavy duty trucks and cranes to move them to the installations site. This is an expensive undertaking and makes for a slow and clumsy process. Only two people are needed to move a barrier by Centurion! Compared to steel and concrete, our thick plastic barriers are stronger, lighter than our competition, and because of their light weight before filling, they’re much faster to install. Superior strength and quality are not compromised with our plastic barriers.

Portability and Manageability Will Save Time & Money

When you deal directly with Centurion Barriers, not only will you save money, but you can be assured that our barriers will withstand a long life in all weather conditions. Water-filled plastic barriers make sense because they stand up to the competition and surpass them in portability. Centurion Barriers are dependable and are exclusive in design. Choose from our different models to suit your needs.

There is a large demand for lightweight barriers that are easier to transport than heavy steel and concrete. Cost savings provide added value as plastic barriers are a good economical solution to any safety application that must have quick and reliable protection. Centurion Barriers offer a maintenance free product and a form of safety protection that is easily managed.

Enjoy Both Cost Savings & Product Reliability

Don’t go through the expense of using extra heavy materials when a simple alternative is available. Our attractive designs will prevent soil erosion, protect people or car parks, or delineate construction zones in slow moving areas. Just because they’re light, doesn’t mean our product suffers in reliability. Rotomolded plastic has UV inhibitors manufactured directly into the barrier and will won’t crack or become brittle. We created a product specifically to accommodate the needs of unique weather conditions in Australia.

Sporting events, shopping centres, and go cart tracks all need the use of barriers, and will all benefit from the use of plastic barriers and save money for their venues. Separate lanes of slow traffic can be quickly and efficiently rerouted while preventing any crossovers and head-on collisions because portable plastic barriers can be installed faster than their steel and concrete counterparts.

Space Saving Equals Cost Savings

More of our lightweight barriers can be transported on one truck than a barrier constructed of steel or concrete, another way you’ll save on transportation costs. A reduction in storage space will add even more value to your plastic Barriers.

Protection and safety must be quickly addressed in unforeseen road hazards. Don’t wait on cumbersome heavy duty cranes. Crew men can attend to paved roads and crowds can more easily be controlled when you choose a lightweight but heavy duty Centurion Barrier.

Things You Need To Know About Vehicle Safety Barriers

Vehicle Safety barriers are specifically designed for steering back all those vehicles that are hitting the barriers. These barriers are designed in such a way so that they can easily achieve the impact to permit vehicles for deform and deflect back on the road. There are some particular vehicles that are vulnerable to vehicle safety barriers like motorcycles, Lorries and all those vehicles with a higher central gravity.

A vehicle safety barrier is a sort of barrier specifically used in designing roads. The basic purpose of designing these barriers is to perk up road safety and put off vehicles from departing the roadway. Moreover, here are some typical sites like mountain roads, bridge supports, multi-lane highways and median separators etc for vehicle safety barriers purpose.

Some improved safety barriers have been designed since the 1990s for lead back and holding up vehicles up to 40 to 50 tons. Besides that, there are several other types of vehicles safety barriers designed on permanent and semi-permanent basis. Some of these vehicle barriers can include:

Automatic Lift Arm Barriers

These types of barriers can be lined with access managing option on unlimited basis like coin machines, token, vehicle identification tags, remote control, proximity cards etc that can easily be integrated with accessible security mechanisms.

Automatic Lifting Kerb

Automatic Lifting Kerb barriers are specifically operated, functioned and developed through a metal plate welded steel material. The ultimate use of these barriers is to put off interruption through lifting up from the road outside to present a vehicle barrier crosswise the entrance of a specific roadway. These barriers can correspond to approximately 800mm in altitude and 5 meters in length.

Commercial and Domestic Mechanical Bollards

Mechanical bollards are particularly designed to confine right of entry in both domestic and commercial regions. These mechanical bollards are ideally fit for commercial roadways without charging no more than 50% duty cycle.

Safety Mechanical Bollards

Safety Mechanical Bollards can be operated through a manual or automated mechanism. Under manual operation, it is merely laid aside horizontally and then shifted to a vertical place and locked in. Similarly, automated vehicle type is typically developed into the ground and then lifts up to put off vehicle imposition.  It is advised to inspect into detail the accurate location of this kind of bollard before its installation.

Traffic Stream Control Plates & Safety Posts

Lots of these automated type barriers can be slotted into a survived safety mechanism just like the use of safety cameras with number plate identification capabilities.

The Benefits of Rotational Moulding in Polyethylene Barriers (Part 1 of 2)

Part 1 of 2

Rotational moulding is a production process that involves a heated hollow mould which is filled with a certain quantity of plastic, then slowly rotated in order for the melted material to disperse and stick to the walls of the mould. The rotation continues in the cooling stage, after which the mould can be opened to retrieve a complete hollow plastic object with walls of even thickness. This method has found many applications in industrial processes among them in the production of superior quality plastic barriers.

In this 2-part article we will look into the effects of weather elements on plastic, especially in the context of the South Pacific and New Zealand climate, and continue to elaborate on the counteracting effects of rotational moulding or rotomoulding and its application in water filled barriers. First of all, in order to better understand the importance of rotomoulding on exterior use plastics such as water filled barriers we need to look into the effects weathering factors can have on plastic.

Sunlight and humidity take a toll on appearance

The first symptom of weathering is visible in the colour that will soon start fading and yellowing due to the chemical reactions caused by sunlight and oxygen. To be more specific, what really damages plastic is not sunlight per se but solar radiation or UV light that initiates a destructive reaction on polymer chains, making plastic become brittle over time.

In humid climates in particular, this is usually accompanied by the polymer chain scission resulting in slow erosion and roughening of the plastic’s smooth surface. This starts a domino effect with underlying layers beginning to erode in turn and losing pigment as they are exposed to the elements. Appearance wise this means that the plastic will lose its initial glossy colour since light no longer reflects on a smooth surface. Rather it scatters looking faded and worn out.

Fluctuating temperatures make matters worse

Weather cycles and extreme weather variations from wet to dry and hot to cold and vice versa will also take their toll on plastic causing it to continually shrink and swell, and triggering a cracking of the surface. The latter, apart from affecting appearance, will also have an impact on the plastic’s mechanical properties such as tensile and impact strength and thickness.


Temperature alone can have a devastating effect on plastic causing a dramatic doubling of the breakdown process whenever the thermometer rises by 10 degrees C. Now, imagine all those factors combined – as is the case in real life conditions – and you can clearly see the amount of stress exerted on outside plastics that can accelerate normal weathering. This seen in the context of the South Pacific and New Zealand climate, where the combined effect of high UV and humidity levels is much more prominent, means bad news for plastic components that have to be exposed to the weather elements all year round.

Continue reading part 2 of the article, where we will see how this affects polyethylene barriers that are meant to be exposed to the elements for long periods and, most importantly, how we can counteract and significantly slow down the breakdown process.

Water Filled Barriers: When and Why to Choose Them

Where portability is important, water filled barriers are here to stay. With their versatility and economy they revolutionise construction zone delineation, temporary rerouting of traffic as well as redirecting and warding off pedestrians. This article will examine the advantages of water-filled barriers over their concrete predecessors.

Water Filled Barriers

Great Portability Equals Time and Cost Efficiency

Weighing only a fraction of their weight when empty means that water filled barriers can be set up at a fraction of the effort, time and cost a concrete barrier would require, reducing transportation costs to a minimum. This makes them ideal as temporary barriers for sporting events, shows, car parks, ports, airports, construction zones and any type of emergency where fast deployment is of the essence.

Note that when empty, these plastic barriers weigh no more than 28kg each, which enables them to be deployed by a single person. This gives you the freedom to easily reposition your barriers ad hoc and allows you to save a fortune on hiring forklifts. Once set up, the barriers are then filled with water that can be easily drained through a drain plug located at the bottom.

Versatility and Practicality

Available in bright colours, polyethylene barriers are clearly discernible even from a distance. Because they are made to stand out, they serve as a warning sign clearly outlining boundaries and safely channelling traffic and pedestrians. What makes them even more versatile is that they can accommodate a range of add-ons to suit various occasions, such as banners, company logos, safety and flashing lights, warning sings, signage and hoarding panels that obstruct visibility altogether.

Another extremely versatile feature that gives water-filled barriers a competitive edge over concrete barriers is that they can be equipped with male/female ends that allow them to interlock with one another, creating a seamless line of barricades. This serves as a pivot point that not only provides variety in the angles they can be deployed but it also reinforces each individual barrier and the entire structure as a whole, allowing the units to swing if impacted instead of toppling.


To sum up, water filled barriers can find application anywhere where crash protection against high speed errant vehicles is not a priority. Even so, one should bear in mind that not all water filled barriers are constructed to be the same. There are different types of barriers suitable for different purposes and of course one should not ignore construction quality that will ensure your barrier of choice will withstand wear and tear like a champion even when exposed in the harshest conditions.

Confident about our products’ superior quality, we at Centurion Barrier Systems Australia extend a 5-year manufacturer’s warranty on all our competitively priced products. So, if you have opted for a water filled barrier browse through our online catalogue and feel free to contact us for expert advice tailored to your needs and budget.

What is Rotomoulding?

Rotational plastic molding is an extremely versatile and economic process that relies on gravity and heat to produce parts with exceptional strength. The finished result is a stress-free, lightweight and seamless design that is very durable.

A variety of plastic resins are available to use, depending upon the product specifications, strength requirements and resistance to other substances required. Materials that may be selected include polyethylene, nylon, polycarbonate, polypropylene, polyvinylchloride (PVC) and custom formulated compounds,

The flexibility of RDP’s process allows for a wide range of shapes and sizes to be manufactured. RDP also offers products in a wide range of colors, with graphics molded directly into the part.

Steps in the rotational molding process:

  1. After the type of resin is selected, a premeasured amount of plastic resin is placed into a mold.
  2. The resin melts and fuses in a three-stage process. After the resin is loaded into a mold, the mold is inserted into an oven and rotated on two axes at low speed until the resin coats the inside surface of the mold cavity, fusing into a uniform wall thickness.
  3. While still rotating, the mold is removed from the oven and is cooled gradually.
  4. The rotation ends when it reaches the temperature that the part can be safely removed from the mold.
