Steel Bespoke Security Roller Barrier

Rolling barriers are barriers with rollers installed on it. The concept of rolling barrier is a structure equipped with pipes covered with roller rings. Rolling barrier activates the rolling friction when vehicle collides with it, and with rolling friction activated it reduces the severity of the accident. The roller on the barriers start to roll when it is hit by a vehicle and prevents vehicle from being suddenly stopped or overthrown, and thus reduce the severity of accident. Rolling barriers can be used as roadside barriers, median barriers, barriers on curves, etc. But it’s use can be proved more effective on horizontal curves, where there is high chance of accidents.

Components Of Rolling Barrier System: 

1.Top rail: There are two rails in rolling barrier system, which connects and supports the rollers horizontally. The upper rail is known as Top rail. It is like a guard rail, made of steel. Top rail splice is used to connect pipe with rails.

2.Bottom rail: From the two rails, the lower rail is called Bottom rail. It also connects and supports the rollers horizontally. It is like a guard rail, made of steel. Bottom rail splice is used to connect pipe with rails.

3.PVC Pipe: The rollers are installed on PVC pipes, which allows the rollers to rotate or roll freely. It is a vertical member connecting both the rails and rollers. It is made up of PVC or steel.

4.Stopper boards: It is a disc like board, which is installed between rollers and rails, at both upper and lower sides. It is used to guide objects back to road.

5.Shock absorbing roller: It is the main part of rolling barrier system. The rollers are usually made up of Urethane or recycled hard rubber. It absorbs the shock of vehicles, and convert impact energy into rotational energy.

6.LED guide lamp: A small LED guide lamp is installed on PVC pipe. It is installed on top of PVC pipe.

7.Reflective band: A reflective band is attached to the rollers to give better visibility at night. Yellow coloured reflective band/tape is used to increase visibility at night.

Roller Barrel Material:

Urethane has become the material of choice in so many of today’s performance driven applications because it exhibits extraordinary physical and mechanical properties that other materials simply can’t match. It is a type of an artificial rubber. Urethane is flexible and malleable. It possesses non-brittle property along with elasticity.

Polyurethane is also used for rolling barriers. Polyurethanes are linear polymers that have a molecular backbone containing carbamate groups. They are unique in combining the strength of rigid plastics with the flexibility and elasticity of rubber. It also possesses non-brittle property along with elasticity.

Use of recycled artificial rubber is also possible.
