Road guardrail manufacturers are used in the production of this road guardrail. Zinc rod surface treatment using hot dip zinc process, zinc steel road guardrail is not easy to rust because the raw material has a strong corrosion resistance.

The appearance of the steel road guardrail will also use the color polymer simulation enamel electrophoresis high-temperature curing process, which is very high strength, more than 10 times that of ordinary guardrail. Under the surface protection of this strength, the capabilities of zinc-steel road guardrail have been improved to a certain extent. Zinc-steel road guardrail can withstand 50 kilograms of impact force per square centimeter, in the anti-oxidation,. Ability is very... Rain and fog weather is not easy to rust.
