The three-wave guardrail usage: express road, provincial road, county side road, township road, mountain road, seaside road and so on.The specification of the three corrugated beam is 4320 mm, the wave width is 505 mm, the wave height is 85mm and the plate thickness is 4mm. Theoretical component: 102kg, cooperation 130*130 square pipe column.
Thrie beam Guardrail
Features of Thrie-beam Galvanized Corrugated Beam:
1, High-quality range ( Q235/Q345) material，the surface is hot dipped galvanized, the effect of anti-corrosion and waterproof is better.
2, Wider panel, larger anti-collision area, and better anti-collision effect.
3, Smooth edge design. Prevent accidental cutting when installation and more safety.
4, Comprehensive protection: every part of the plating can be plated with zinc, which can be fully protected even in the depression, sharp corners and hiding places.
5, Durable: in the suburbs, the standard hot-dip galvanized rust resistance can be kept for more than 50 years without having to be repaired; In urban or offshore areas, the standard hot-dip galvanized coatings can be kept for 20 years without having to be repaired
