Description

W-beam guardrail is a kind of road crash barrier used for securing highway safety by preventing errant vehicles from sliding out of the roads and impacting the roadside buildings or other objects. So it is most commonly fixed on the side of the highways, dock areas, aisles, especially on curves and slopes for protection against run-off-road collisions.

Our W-beam guardrail product is formed in accordance with the latest highway safety barrier technology for making sure its high durability and maximum strength. It is made of high quality steel, which reduces the impact force caused by mobile equipment to the maximum extent. Meanwhile, the zinc coating or PVC coating perfectly combined to the W-beam guardrail keeps the products free of damages of corrosion and rust.

For the time being, W-beam guardrail is the most popular choice for making crash barrier systems. W-beam guardrails are cost-effective to prevent vehicular impact with roadside objects, and lessen the likelihood of vehicle overturning and casualties.

W-beam road guardrail crash barrier is formed in accordance with the latest highway safety barrier technology to make sure its high durability and maximum strength. Dachu road guardrail components are made of high quality steel (Q235, Q345, A36 etc.), which can effectively reduce the impact force caused by vehicles to the maximum extent.

To make things better, the zinc coating or PVC coating perfectly combined to the W-beam guardrail keeps the products free of damages of corrosion and rust.

Road Safety W-Beam Barrier can be easily inserted into the pre-installed insertion and extraction holes by means of the plug-in column, which serves as isolation and protection. At the same time, it cooperates with the guardrail on the outer side of the road, and is neat and uniform.

When the vehicle collides with it, the corrugated steel guardrail board has good crash worthiness and energy absorption, and it is not easy to be destroyed, and at the same time it can protect the vehicle and the passengers.

When the road maintenance or other reasons need to be connected, the groups of guardrail columns at the opening can be easily removed and removed to open the passage for the vehicle to pass.

Easy installation: just attach the beam directly to the post, no need of blocks.
Advantages:

Prevent the mobile equipment from skidding off the road by redirecting it

Minimum the damage of errant vehicles

High quality material and anti-rust surface for longer service life

Corrosion resistant

Can be repaired quickly after accident
