"Hot Dip Galvanized Steel in Coils/Sheets Hot dip galvanizing plate, heat plating for short, is the carbon steel substrate after preprocessing, immersed in molten zinc liquid state, obtain the protection process of coatings. First, the starting material must be a steel sheet that meets specific requirements and has a clean surface, free of any impurities such as oil, rust, etc. Next, the steel sheet undergoes a pickling process to remove oxides and oil from the surface, thereby ensuring the cleanliness and finish of the surface. This step is essential to improve the adhesion and uniformity of the zinc coating. After pickling, the steel sheet undergoes a cold rolling process to achieve the required thickness and mechanical properties. The cold-rolled steel sheet is then immersed in molten zinc and hot-dip galvanized to form a zinc-steel alloy layer through a chemical reaction between the zinc and the steel sheet. This is the most core link in the entire galvanized sheet production process and directly determines the thickness and quality of the zinc coating. Once galvanizing is completed, post-treatment steps such as passivation may be required to improve the corrosion resistance and aesthetic appearance of the zinc coating. Afterwards, the galvanized steel sheet undergoes a cooling and straightening process to restore its normal shape and size. Finally, according to customer needs, the steel plates are cut into appropriate sizes using a cutting machine and packaged,
