Thrie 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.
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.
