Safety barrier It refers to the road guardrail. What is the raw material of the road guardrail? Let's see!

  The main function of road guardrail is to ensure that there is no danger for vehicles, traffic flow and pedestrians. It not only requires that the road guardrail has certain anti-collision performance, but also requires that the road guardrail has beautiful features. So what is the manufacturing material of the road guardrail?

Many road barriers are mainly made of low-carbon steel wire. The reason why people use this raw material to make guardrails is that it belongs to environmental protection materials. Secondly, this material is not easy to be aged and corroded in the process of use, and it also has strong collision resistance. Its hardness is also high. Of course, there are The comprehensive performance of PVC road guardrail is not inferior to that of low-carbon steel wire.

The raw materials of zinc steel guardrail profiles are high temperature hot-dip galvanized materials. Hot dip galvanizing refers to putting high-quality steel into thousands of degrees of zinc bath. After a certain period of immersion, the zinc liquid will penetrate into the steel and form a special zinc steel alloy. The surface of hot-dip galvanized materials is not treated in the field environment such as highway guardrails and high-voltage iron towers, It has not rusted for 30 years. It has been solved for many years by using high-temperature hot-dip galvanized materials after 30 years of anti rust treatment.

  Raw material characteristics of zinc steel guardrail:

1. The raw material is hot-dip galvanized steel strip of various specifications, which adopts precious high-frequency welding technology, and the welding is smooth and firm.

2. The zinc content on the surface of galvanized steel pipe is 60-80mm2, which can prevent rust for 3-5 years under normal temperature.

  3. Galvanized steel guardrail products are further processed for galvanized pipes. The process flow of zinc steel guardrail: mechanical processing → chemical treatment (degreasing → ash removal → phosphating → passivation) → electrostatic spraying (curing (220 ° high temperature imitation enamel curing). After multiple processing, it can be rust free for 20 years.

  4. Zinc steel products are especially characterized by non welding. The pipe fittings developed by zinc steel are perfectly combined with the pipe materials to meet the standards of the International Fence Association for beauty, firmness and applicability.

  5. The product surface has powder coating. Its products are beautiful in appearance, color can be matched at will, color is better than rainbow, no welding and interpenetrating combination are required, and have strong protection function, self-cleaning and environmental protection, so as to achieve true low-carbon environmental protection and green life products.
