The advantages of Z80 DX51D Galvanized Steel Coil are mainly manifested in the following aspects:
1. Processing performance
Z80 DX51D Galvanized Steel Coil can fully meet the requirements of rolling, stamping, bending and other forms of processing.
2. Corrosion resistance
Z80 DX51D Galvanized Steel Coil has excellent corrosion resistance, and the service life is 6 times that of hot rolled and cold rolled steel under the test of the same thickness and surface treatment.
3. Heat resistance
Z80 DX51D 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 Z80 DX51D Galvanized Steel 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 400mpa, the tensile strength is between 300 and 550mpa, and the elongation is between 28% and 40%.

10.FAQ of Hot Dipped Galvanized Steel Coil

1.Is hot dipped galvanized steel same as galvanized?
Hot-dipped galvanized steel is a type of galvanized steel. Hot dipped galvanizing process is practical, and the galvanized product is very durable, versatile and highly corrosion-resistant.
2.What is the difference between G60 and G90 for galvanized steel?
G90 galvanized steel are coated by the coating weight of zinc 0.90 oz/ft^2 while G60 galvanized steel are 0.60 oz/ft^2.
That is to say,
G90 galvanized steel are coated by the coating weight of zinc 275g/m^2 while G60 galvanized steel are 180g/m^2
Therefore, G90 galvanized steel are a longer service life than G60.
3.What are galvanized steel coil used for?
Hot dipped galvanized steel coil are most applied to roofing sheet in construction.
