Hot-dipped galvanized steel strips refer to steel strips that have undergone a process called hot-dip galvanizing to protect them from corrosion. This process involves immersing the steel strips into a bath of molten zinc, which forms a protective zinc coating on the surface of the steel. Before the hot-dip galvanizing process begins, the steel strips are typically cleaned to remove any surface contaminants, such as rust, grease, and mill scale. This ensures good adhesion of the zinc coating to the steel. The cleaned steel strips are then immersed into a bath of molten zinc, which is typically maintained at a temperature around 860°F (460°C). The zinc bath is often contained in a specialized galvanizing kettle. When the steel strips are immersed in the molten zinc, a metallurgical reaction occurs. The zinc chemically bonds with the steel's surface to create a zinc-iron alloy layer on the steel. This alloy layer provides excellent corrosion resistance. After a specific duration in the zinc bath, the steel strips are carefully withdrawn. As they are removed, excess zinc is allowed to drain off. The coated steel strips are then cooled, often by air or water quenching, to solidify the zinc coating.
