"METAL CRASH BARRIER" (Guard Rail) is probably something most people don't think about, that is, until it saves their lives. It is a proven road safety system, and is brought to you by THAKKARSONS ROLL FORMING PVT. LTD. which undertakes design, manufacturing and installation of wide range of Guard Rails under stringent quality control.

The basic function of Guard Rails is to absorb the impact energy of the colliding vehicle thus minimizing the extent of risk and damage to the vehicle and its passengers.

Besides, it prevents the vehicle from rolling down high embankments and veering off the carriage way. Thus, Guard Rails find its typical application on Highways, Bridges and Flyovers.
Based on the guidelines issued by Ministry of Surface Transport (MOST) and other international specifications like AASHTO M180, Thakkarsons Roll Forming Pvt. Ltd. offers "W" beam and "Thrie" beam type steel crash barrier systems.
