Product Description

Thrie Beam Guardrail 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.

Three-wave 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.

Advantages:
1. Higher durability and strength than W-beam guardrails
2. Absorb maximum energy of the impact force
3. Redirect the mobile equipment as fast as it can
4. Visual remand of the transition to highways or bridges
5. Preventing the pedestrians from walking across highways ignoring the running cars
6. Protect the vehicles against skidding off roads, especially mountain roads and bridges.
