Hot-dip Galvanized Steel Sheet in Sheet

Description：

The most external layer is all zinc, but successive layers are a mixture of zinc and iron, with an interior of pure steel. These multiple layers are responsible for the amazing property of the metal to withstand corrosion-inducing circumstances. Zinc also protects the steel by acting as a "sacrificial layer." If rust does take hold on the surface of Galvanized Steel Coil, the zinc will get corroded first. This allows the zinc that is spread over the breach or scratch to prevent rust from reaching the steel.

Once the steel is refined, it is cast into slabs or billets, which are then reheated in a furnace to a temperature suitable for rolling. The reheated steel is then passed through a series of rolling mills, where it is shaped and reduced in thickness to form a continuous sheet. The rolling process involves multiple passes through the mills, with each pass gradually reducing the thickness of the steel and improving its properties. After the rolling process, the steel sheets are often pickled and treated with various coatings or finishes to improve their surface quality and corrosion resistance. Finally, the sheets are cut into specific sizes and may undergo additional processing, such as tempering or annealing, to further enhance their mechanical properties. Overall, the process of manufacturing steel sheets involves a combination of refining, casting, rolling, and finishing processes to produce high-quality sheets that meet the desired specifications.
