First step
The entire roll of steel strip is pickled and decontaminated to make the surface bright and clean.
Second step
①Hot-dip zinc: After pickling, clean it in an aqueous solution of ammonium chloride or zinc chloride or a mixed aqueous solution of ammonium chloride and zinc chloride. Then it is sent to the hot dip plating tank for galvanizing.
②Hot-dip galvanizing: After pickling, it is cleaned in an aqueous solution of ammonium chloride or zinc chloride or a mixed aqueous solution of ammonium chloride and zinc chloride. It is sent to a continuous annealing furnace and then entered into a galvanizing tank for galvanizing.
③Direct galvanizing: After pickling, it is sent to the continuous annealing furnace and then into the galvanizing tank for galvanizing.
Third step
After galvanizing, the steel strip is coiled up and stored in the warehouse. The galvanized layer can be customized according to customer requirements, generally not less than 50g/square meter, and any sample must not be less than 48g/m².
