Hot-Dipped Galvanized Steel Coil Manufacturer

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.

Surface Finish

Regular Spangle: This is the most common finish, characterized by a visible crystalline pattern on the surface. It is created during the cooling process when the zinc coating solidifies.

Minimized Spangle: This finish has a smaller and less visible crystalline pattern compared to regular spangle. It is often used for applications requiring a more uniform appearance.

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.

Yes, it could be oiled. 8-20g per square meters. Oiling can prevent the oxidation of galvanized sheets in a short time.

Galvanized Steel Coil and Strip 9

For galvanized strip, the quality of its quality mainly depends on the material and heat treatment of the strip, as well as the amount of zinc applied to hot-dip galvanizing. , 120 grams, at present, the weight of zinc in many factories is only about 40 grams, and the weight of zinc directly affects the anti-corrosion ability.

For the galvanized strip steel with poor quality, there are cracks on the surface, which are mostly caused by cracks and poor annealing, and the material is too hard.
