Introducing our top-of-the-line Galvanized Steel Coils, designed to meet the highest standards of quality and performance. Engineered with precision and coated with a layer of zinc, our galvanized steel coils offer superior corrosion resistance, making them ideal for a wide range of applications.
Hot-dipped galvanized steel coil is a type of steel product that has been coated with a layer of zinc to protect it from corrosion. The process involves immersing the steel coil into a bath of molten zinc, which forms a metallurgical bond between the zinc and the steel.
This coating provides a durable and long-lasting barrier against rust and other forms of corrosion, making it ideal for use in various applications such as construction, and manufacturing industries.

Check tariffs before ordering from China.
The life of galvanized steel coil depends on the end application and environment, as well as the weight of zinc. For example, the life of z275 galvanized roof in a marine environment is 5 years.
The life of z180 cable tray in an indoor environment is 15 years.
The price of galvanized steel coil depends on the raw material hot-rolled, the zinc weight, and the width and thickness of the coil.
