Hot Dipped Zinc Steel GI Galvanized Coil

Hot Dipped Zinc Steel GI Galvanized Coil are processed by continuous hot-dip galvanizing from cold-rolled steel coil. Zinc coating on both sides can effectively prevent corrosion and rust and increase the service life of steel plate.

WITOP Steel has advanced testing equipment and a professional team. WITOP Steel strictly controls the quality at each step of production, including inspection of raw materials, product thickness and width tests, zinc coating tests, T-bend tests, impact tests, tensile tests, color difference analysis during production, salt-spray tests, and package testing on exported steel coil, which ensures its integrated performance and quality.

The advantages of hot-dipped zinc steel GI Galvanized Coil are mainly manifested in the following aspects:

1. Processing performance

Hot Dipped Zinc Steel GI Galvanized Coil can fully meet the requirements of rolling, stamping, bending, and other forms of processing.

2. Corrosion resistance

Hot Dipped Zinc Steel GI Galvanized Coil has excellent corrosion resistance, and the service life is six times that of hot rolled and cold rolled steel under the same thickness and surface treatment.

3. Heat resistance

Hot Dipped Zinc Steel GI Galvanized Coil can be used for a long time in an environment of 315 degrees without changing color, while other steel sheets are just used at a temperature of only 230 degrees, and 250 degrees will change color.

4. Mechanical properties

The mechanical properties of hot-dipped zinc steel GI Galvanized Coil are significantly higher than those of hot-rolled and cold-rolled steel sheets, which are mainly manifested in yield strength, tensile strength, and elongation. The yield strength of galvanized steel sheet is between 300 and 400 MPa, the tensile strength is between 300 and 550 MPa, and the elongation is between 28% and 40%.
