The hot-dip galvanized corrugated guardrail is made of high-quality Q235 strip steel after rolling (double-wave, triple-wave), pickling, and finally hot-dip galvanized anti-corrosion treatment. It is currently the most widely used in the highway anti-collision corrugated guardrail A sort of. Hot-dip galvanized corrugated guardrail product features: it has the advantages of good impact resistance, low cost, long life, higher safety, and environmental protection.

Next: The hot-dip galvanized pipe reacts the molten metal with the iron substrate to form an alloy layer, which combines the substrate and the coating. Hot-dip galvanizing is to pickle the steel pipe first. In order to remove the iron oxide on the surface of the steel pipe, after pickling, it should be washed with ammonium chloride or zinc chloride aqueous solution or a mixed aqueous solution of ammonium chloride and zinc chloride, and then sent to a hot-dip coating tank. Hot-dip galvanizing has the advantages of uniform coating, strong adhesion, and long service life. The hot-dip galvanized steel pipe substrate undergoes complex physical and chemical reactions with the molten plating solution to form a dense, corrosion-resistant zinc-iron alloy layer. The alloy layer is integrated with the pure zinc layer and the steel pipe substrate, so it has strong corrosion resistance.
