Galvanized steel sheet is hot dipped zinc coated galvanized steel sheet with good anti-corrosion property. Hot dipped zinc coating is a cost-effective way to prevent steel material getting rusty. GI sheet is short form of galvanized iron sheet. The normal surface of galvanized sheet is big spangles small spangles and zero spangles. HDG sheet is mainly used in construction, light industry, automobile making and other commercial fields. Hot dipped galvanized iron sheet is a kind of steel or iron sheet is with layer of zinc to prevent from rusting to extend service life.

Galvanized sheet is refers to the surface has a layer of zinc plated steel plate. Galvanized steel sheet is a frequently used economic and effective anticorrosion method, about half of the zinc production in the world are used in this process. Galvanized steel is to prevent the steel plate surface from corrosion to extend its service life, in the steel plate surface coated with a layer of metal zinc, the zinc coated steel plate are called galvanized iron sheet. In general, the thicker the permissible error of galvanized sheet, rather than a fixed 0.02 0.04 mm, thickness deviation according to the yield and tensile coefficient also different and have different requirements, such as width deviation generally in 5 mm, the thickness of the plank generally between 0.4 to 3.2.
GI Steel Coil gets coated in layers of zinc because rust won't attack this protective metal. 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 GI 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. For countless outdoor, marine, or industrial applications, GI Coil is an essential fabrication component.
