Hot-Dip Galvanized Angle Iron, also known as hot galvanized angle iron or zinc-coated angle iron. It involves immersing the degreased angle iron in a molten zinc bath at approximately 500°C, which coats the surface with zinc to prevent corrosion, suitable for environments with strong corrosives like acidic, alkaline fumes, etc. Process: The hot-dip galvanized angle iron process includes angle iron acid washing → water washing → dipping in pretreatment solution → drying preheating → hanging galvanizing → cooling → passivation → cleaning → polishing → complete hot-dip galvanizing. The zinc coating on hot-dip galvanized angle iron is evenly thick, ranging from 30-50um, with high reliability, as the zinc coating is metallurgically bonded to the steel, becoming part of the steel surface, hence the durability of the coating is quite reliable. Since the raw material is angle iron, it is categorized similarly.
