Roadside barriers have been developed over the years to safely redirect vehicles that leave the roadway. Many different rigid, semi-rigid and flexible designs for roadside barriers have been evolved. The most common system consist of a steel w-beam rail supported on steel posts with end treatments and transitions of various designs using similar materials, that's our guardrail, it can be hot dip galvanized or sprayed.
Our guardrails are designed in pursuance to the principle of keeping the vehicle inside the road in a secure way and at the same time minimizing the loss of life and property in case of an accident.
