Product Description

Steel Beam Guardrail

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.There are mainly two specifications of steel guardrail: W-Beam guardrail and Thrie-Beam guardrail, They are manufactured from Q235B or Q345B grade steel in 2.5-4mm base metal thickness as supplied by China Steel Limited.All products are hot dipped galvanized or powder coated after fabrication to meet the requirements of Chinese National Standards,AASHTO M180 Standard, SANA 1350 Standard and etc.
Thrie beam guardrail features its shape of three waves, which has an added corrugation on the basic of traditional W-beam. Compared to two-wave shape products, this one has a stronger construction and higher impact endurance. It has been successfully impact-tested by a heavy truck and has showed its remarkable resistance against the crash force.It is a perfect combination of high quality material (including Q235, Q345, etc.) and excellent anti-rust zinc or PVC coating. All of these make it outstanding at long-term corrosion and rust resistance. Meanwhile, it costs effectively and is widely used as a visual and physical barrier for protection against run-off road collision. Additionally, it is often used as a specific signs for a transition to high speed roadways, bridges, etc.
