Products Description
hrie beam guardrail
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.

Thrie Beam Guardrail Advantages
* No offset block required
* Higher durability and strength than W-beam guardrails
* Absorb maximum energy of the impact force
* Redirect the mobile equipment as fast as it can
* Visual remand of the transition to highways or bridges
* Preventing the pedestrians from walking across highways ignoring the running cars
* Protect the vehicles against skidding off roads, especially mountain roads and bridges.
