Weld Zinc Supplementation Method in Galvanized Barrel Production
Galvanized steel sheets are commonly used in the production of steel galvanized barrels. Since the steel sheet itself has a galvanized layer, it generally does not need to be painted again. In the production process, the seam welding of galvanized steel sheets destroys the galvanized layer at the weld, thereby destroying its corrosion resistance and aesthetics. Therefore, after the barrel body is welded, the weld part must be replenished with zinc to restore its original function. Let's first talk about the difference between steel galvanized barrels and electroplated steel barrels.
