◉ Product Details

Galvanized steel coil is a kind of steel sheet material formed by galvanized steel strip, which is based on hot-rolled steel strip or cold-rolled steel strip. Its surface has a layer of zinc, this layer of zinc can effectively prevent rust and corrosion of the steel strip, thereby extending its service life.

Galvanized steel coil has a wide range of applications in industrial production and construction, such as building structures, electrical equipment, automobile manufacturing, petrochemical and other fields. Because there is a layer of zinc on its surface, it can effectively improve the corrosion resistance of the steel strip, so in some structures that need to be exposed to the natural environment for a long time, the use of galvanized steel coil can effectively reduce the frequency of maintenance and replacement, thereby reducing costs.

The manufacturing process of galvanized steel coil includes the following steps: First, the steel strip is cleaned and annealed to remove surface impurities and stresses; Then it is immersed in the molten zinc liquid to make its surface adhere to a layer of zinc; Finally, it is cooled and sheared. After these steps, the galvanized steel coil is manufactured.

In short, galvanized steel coil is a steel sheet material with excellent corrosion resistance, which has a wide range of applications in industrial production and construction.

Material introduction

Galvanized steel is a kind of steel after galvanized processing, which can effectively prevent steel corrosion and rust, thereby extending the service life of steel.

The coating of galvanized steel has strong toughness and can withstand mechanical damage during transportation and use. Galvanized steel is mainly used in the construction and manufacturing industry, because of its corrosion resistance, high strength, good durability, is widely used in a variety of building structures and mechanical equipment.

The coating of galvanized steel is usually divided into two kinds: electric galvanizing and hot-dip galvanizing, of which hot-dip galvanizing has a better anti-corrosion effect. Galvanized steel is often used in building external walls, glass curtain walls, marble curtain walls and other columns and stress materials, or used in outdoor telecommunications towers, highways and other open-air buildings.
