DC51+Z galvanized coil is a hot-dip galvanized steel Roll made of high-quality cold-rolled substrate through the hot-dip galvanizing process. This product has excellent corrosion resistance and good processing performance and is widely used in construction, home appliances, automobiles, machinery manufacturing, and other fields.

Product Description


 Product Description

DC51+Z gi coils

The galvanized layer of DC51+Z galvanized coil is uniform and dense, has good adhesion and corrosion resistance, can effectively prevent oxidation and corrosion of the steel surface, and prolong the service life. At the same time, the galvanized layer also has good decorative properties and can provide a beautiful appearance.This grade of cold-rolled substrate has excellent forming performance and weldability, and is suitable for various processing technologies such as stamping, bending, shearing, etc. Its excellent processing performance makes DC51+Z galvanized coil an ideal material for manufacturing various components and parts


 Surface Structure

the structure of DC51+Z gi coils


The substrate is made of a high-quality cold-rolled steel plate with a flat surface and certain mechanical properties. It provides the strength and rigidity of the DC51+Z galvanized coil and provides a guarantee for the structural support and seismic performance of the product.

The galvanized layer is a layer of zinc formed on the surface of the substrate by the hot-dip galvanizing process. The galvanized coating is mainly composed of pure zinc and has a uniform and dense structure. It can effectively prevent oxidation and corrosion on the surface of the substrate and provide excellent corrosion resistance.

The galvanized layer of DC51+Z galvanized coil has good adhesion and is not easy to peel off. The thickness of the galvanized layer can be adjusted according to customer needs, generally between 20-60μm. Thicker galvanized layers can provide better corrosion resistance and are suitable for more severe environmental conditions.
