Product Details


Our W beam guardrail is two wave corrugated sheet beam steel highway guardrail. W-beam guardrail is a kind of economical and efficient longitudinal guardrail, which is designed to lessen the severity of cross over and run-off-road crash, avoid colliding with objects nearby roadbed, and reduce the possibility of vehicular turnover by w beam guardrail deflection.

W-beam barrier is the most common energy absorption and redirection barrier on highways and expressway all around the world thanks for their high efficiency and low production cost.

W-Beam highway guardrail is a semi-rigid barrier which include W Beams installed on a guardrail post and spacer. W beam guardrail profile has the same section properties internationally used, and we can provide different types of guardrail posts and spacer blocks according to a variety of international standard.

There are mainly two categories of guardrail beams and so many national variations of posts and spacer block based on AASHTO standard guardrails and EN standard guardrails. For example, the main difference of those systems is the post section where the U.S.A uses a H post and Germany using a sigma post. AASHTO M180 designate 2.67mm thickness W Beams of steel grade Gr. 50 or 345 with the domain system in European countries being 3mm thickness W beams of EN Standards S235JR steel. And the spacer block varies from nation to nation.

Guardrail post without spacer design of W-Beam guardrail may lead to wheel snagging, and adding a block between W beam and post is a perfect way to solve this issue.

Practice shows that W-shaped steel guardrail has a good effect in lessening the frequency and seriousness of collisions. A traffic research council study shows that guardrails have more than 97% of effective in reducing casualties.

Since its original development in the 1960s, w-beam crash barrier has protected thousands and millions of passengers and pedestrians by controlling or deflecting vehicles to prevent them from being collided by roadside objects.

We are w beam guardrail factory and manufacturers in China. Our w beam guardrail price is competitive and save client’s budget on w beam guardrail cost.

We do not keep a large stock of W-shaped steel rails, we can produce and supply big quantities of vehicle barriers at competitive prices.
