Thrie Beam Roadside Guardrail , Galvanized Guard Rail For Traffic Road Safety Use

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.

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.

What kind of thrie beam guardrails can we supply?

According to the surface treatment, we can classify our thrie beam guardrails into two types: hot dip galvanized and PVC coating as shown in the following pictures.
