Product Introduction

Galvanized coil refers to a product that is coated with a layer of zinc on the surface of the steel plate to prevent corrosion and rust on the surface of the steel plate. It has excellent corrosion resistance, good processing performance and a long service life. It is widely used in construction, home appliances, automobiles and other industrial fields.

Product Material Classification

Galvanized coils can be divided into the following categories according to the base material and process:

Hot-dip galvanized coils: produced by hot-dip galvanizing process, with uniform coating and strong adhesion.
Electro-galvanized coils: produced by electrolytic process, with smooth surface and high precision.
