DX51D Z50 Hot Dipped Galvanized Steel Coil For Roofing Materials

The advantages of galvanized steel coil are mainly manifested in the following aspects:

1.Processing performance
Hot dipped galvanized steel coil can fully meet the requirements of rolling, stamping, printing, marking, bending and other forms of processing.

2.Corrosion resistance
Hot dipped galvanized steel coil has excellent corrosion resistance, and the service life is 3 times than that of hot rolled and cold rolled steel under the test of the same thickness and surface treatment.

3.Heat resistance
Hot dipped galvanized steel 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 galvanized steel sheets 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 400mpa, the tensile strength is between 300 and 550mpa, and the elongation is between 28% and 40%.
