Product Details
Galvanized sheet products are mainly used in construction, light industry, automotive, agriculture, animal husbandry and fishery, and commercial industries.
Galvanization is a manufacturing process involving the application of zinc coating to steel to prevent it from rusting. The zinc coating works to protect the base metal. It does this by acting as a barrier to the various corrosive elements. Therefore, it offers a sacrificial nature that gives a high-quality and long-lasting steel product.
Galvanized sheet metal is one of the most popular types of steel. This is due to its increased strength, extended durability, and formability. The corrosion-resistant property throws its usefulness up a significant notch.
Hot-Dip Galvanization
Hot-dip galvanization is the most widely used method of galvanization. Just as its name suggests,it involves the dipping of the steel in molten zinc.The pool of molten zinc often maintains a temperature of about 860°F (460 °C).After proper cleaning of the base metal chemically, it gets fluxed to eliminate residual oxides.
A metallurgical bond begins to form between the zinc and the intended metal.
After pulling the metal from the bath, the pure zinc mixes with oxygen from the atmosphere to form zinc oxide.Then, the zinc oxide reacts with carbon dioxide to form zinc carbonate. The zinc carbonate makes the final coating on the base metal.
