热镀锌角钢工艺流程：角钢酸洗-水洗-浸助镀溶剂-烘干预热-挂镀-冷却-钝化-清洗-打磨-热镀锌完工。热镀锌角钢的镀锌层厚度均匀，可达30-50um， 可靠性好，镀锌层与钢材间是冶金结合，成为钢表面的一部份，因此热镀锌角钢的镀层持久性较为可靠。 Hot galvanized corner steel process flow: Angle steel acid washing-washing-immersion plating solvent-drying-preheating-hanging plating-cooling-passivation-cleaning-grinding-hot galvanization completed.The galvanized layer of hot galvanized corner steel has uniform thickness, up to 30-50um, with good reliability. The galvanized layer and steel is metallurgical, becoming a part of the steel surface, so the coating durability of hot galvanized corner steel is more reliable.
