Guard Rail

Highway Guard Rail is a life saving device for the people traveling on Highways / Expressways. This highway crash barrier system saves thousands of life facing accident on road. The Highway Guard Rail works as most dependable life saving protective device in hill roads and at sharp bends which is difficult to negotiate.

Each piece of Guard Rail has two basic shapes

W-beam Guard rail has two “humps” and one “valley”. The “Humps” i.e. the convex surface faces towards the traffic. The “Valley” i.e. the concave surface faces away from the lane.
T-beam has three “Humps” and two “Valleys”
