Our W beam guardrail is w shape guardrail for vehicle restraint system. It is a kind of economical and efficient corrugated beam guardrail, which is designed to alleviate the damage and wounds, avoid colliding with objects nearby substructure, and reduce the possibility of vehicular turnover by barrier structure deflection. W beam guardrail is the most common offset blocking barrier thanks for their high efficiency and low cost.
We can achieve high speed industrialization by employing a rolling mill with modernized equipment and machine. Steel sheet 490 Mpa or 70,000 Psi from the mills are slit to be narrower by distributors to meet production operation.
W beam guardrail profile has the same section properties internationally used. There are mainly two categories of w beams and so many national variations of columns and offset block based on American standard and Euro norm. For example, the main difference of those systems is the pole section while the U.S.A uses a H and the U.K uses Z. American standard designates 2.67mm thick with steel grade Gr. 50 or 345 while the domain system in European countries being 3mm of S235JR. Median double w beam guardrail is usually called median guardrail while roadside double w beam guardrail is usually seen in Saudi Arabia and India.
Fabrication after galvanizing is absolutely not permitted because cutting, punching and welding may lead to rust and welding may change the characteristics of the steel.
A traffic research council study shows that guardrails has more than 97% of effective in reducing casualties. Since its birth at the beginning of twenty century, it has protected thousands and millions of lives by controlling automobile to prevent them from being collided by roadside objects.
We are second to none for clients who want to reduce their budget on guardrail cost. With high efficiency for the fabrication of W section guardrail, we can mass produce w shaped guardrail at good prices.
