Galvanized steel coil for construction project

Hot Dipped Galvanized Steel Sheet in Coil (GI) is produced by passing the Full Hard sheet which has undergone the acid washing process and rolling process through the zinc pot, thereby applying zinc film to the surface. It has excellent corrosion resistance, paintability, and workability due to Zinc’s characteristics. Usually, hot-dipped galvanized steel sheet and galvanized steel coil process and specifications are basically the same.
Hot-dip galvanizing is the process of applying a protective zinc coating to a steel sheet or iron sheet, to prevent rusting.
* Excellent anti-corrosion, paintability, and processability due to the self-sacrificing characteristic of zinc.
* Available to select and produce the desired amount of zinc gilded and in particular enables thick zinc layers(maximum 120g/m2).
* Classified as either zero spangle or extra smooth depending on whether the sheet undergoes skin pass treatment.

Galvanized steel coil is one of the hot-selling products. It’s the cost-effective material, which combines durability and smooth appearance. It’s also easy to paint and use. It is available in big, regular, small, and zero spangles. In addition, it features lightweight, aesthetics, and excellent corrosion resistance. Therefore, GI coil has been a new material for many fields, such as construction, shipbuilding, vehicle manufacturing, furniture, home appliances.
