Description
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.

No offset block requiredAdvantages:
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
Application
To provide railing protection to motor vehicles at dangerous road areas such as steep slopes, high embankments, obscure curves/bends, sharp corners.
To absorb sudden impact during collision thus minimizing injury to vehicle and passenger.
To act as a directional railing for vehicles moving in the right direction.
To act as a median barrier for avoiding head on collision.
To act as a protective barrier for pedestrians along the highway.
