Guardrail Introduction 

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.

Road safety barrier system-a roadside device that provides a physical restriction to penetration of a vehicle in a way that reduces the risk to vehicle occupants and other traffic. Its purpose is to contain or redirect an errant vehicle. It is used to shield roadside obstacles or non-traversable terrain features. Occasionally, it may be used to protect people from vehicular traffic.
 
Guardrail Beam Introduction
 
W beam is the world's most widely specified safety barrier system. Highly effective and inexpensive, the most popular means of eliminating the threat from roadside hazards.Being a semi rigid barrier, W beam guardrail provides a desirable outcome for both designer and vehicle occupants. The ability of the barrier to absorb some of the crash energy reduces occupant risk and the deformation of the impacting vehicles.

An important attribute of Thrie-beam guardrail is its high level of performance especially for large vehicles. Due to the greater height of the rail face, Thrie-beam guardrail provides reduced deflection and improved resistance to vehicle vaulting or under running. The reduced dynamic deflection and maintenance demand makes Thri-ebeam guardrail ideally suited for major facilities carrying a high volume of high-speed traffic. Thri-ebeam guardrail should also be used in transition from Flex-beam guardrail to more rigid barriers. This significantly reduces the deflection of the barrier system at transition to the rigid barrier.
