In the daily use of thrie beam crash guardrail barrier, the hot dipped galvanized thrie beam guardrail crash barrier is widely used. The thrie beam guardrail crash barrier would be used in highway (freeway, motorway), bridge safety, viaduct security, danger mountain road, etc. to protect people safety and keep the road a long life.
Advantages of thrie beam highway guardrail
1. Safety: the thrie beam highway guardrail is mostly installed on the roadside where is danger and where the car is with high speed, to keep the car is on the right way and the things or animals go into the road, to ensure people safety.
2. High strength: anti-corrosion thrie beam highway guardrail is made of Q235/Q345 steel, it is high strength with toughness.
3. Long life: after cold rolled, the thrie beam highway guardrail will do hot dipped galvanized in the zine pool with high temperature, improves its antioxidant capacity and corrosion resistance.
4. Eco-friendly: the Q235/Q345 steel, the material of thrie beam highway guardrail, is recyclable and reusable. It can be made the other products once the guardrail is changed and recycled.
5. Easy install and repair: bots and nuts assembly, the thrie beam highway guardrail is easy to install and change the guardrail beam.
6. Beautiful views: we can do powder spray with different color on the thrie beam highway guardrail, make it more beautiful and suitable with the road sight.
7. Cost-effective: compare with the other crash barrier (roller barrier, plastic barrier and so on), the steel highway guardrail is cheaper price and longer life.
Hot dipped galvanized VS cold galvanized
• After hot dipped galvanized (zine coated), the highway guardrail corrosion resistance ability is dozens of times of cold galvanizing.
• Hot dipped galvanized, means it is done with high temperature to make the zine coated more better than cold galvanized.
• The hot dipped galvanized enhance the adsorption capacity of zinc, made a thicker zine layer and strength the corrosion ability.
• Hot dipped galvanizing is all plated zine coated, it can protect the highway guardrail completely.
• The zine layer of hot galvanizing can keep longer than cold galvanizing.
