(Summary description)1. Hot dip galvanizing. Zinc has good corrosion resistance under atmospheric conditions. Galvanizing is a method of sacrificing an anode to protect the cathode metal. Its corrosion life depends on the thickness of the galvanized layer and the corrosion rate. The thickness of the hot dip galvanized zinc layer is generally above 65 um (455 g/m2). The bonding surface of zinc and iron forms a layer of zinc-iron alloy, which enhances the adhesion of the zinc layer. Atmospheric exposure tests were carried out on hot dip galvanized coatings under various environmental conditions abroad. From the test results, hot dip galvanizing can meet the service life requirements of steel cable trays.
