DX53D galvanized coil is a commonly used construction steel with a wide range of material properties and applications, excellent corrosion resistance and good processing performance. In the construction industry, this material is widely used in roofs, walls, floors and other parts that need to resist atmospheric corrosion.

The Z275 galvanized steel coil is kind of a double-sided galvanized carbon steel. This is produced by a metal coating process that passes cold rolled coils through a bath filled with molten zinc.

Z120 is the coating name, which means that the coating thickness on both sides is approximately 120g/㎡ or 36g/㎡ (three-point test). Z120 grade galvanized coil is coated with zinc to make it more durable.

G60 is the coating grade of steel coil after continuous hot dip plating process. G represents the "galvanized" or galvanized layer of the product. The number 60 refers to the weight of the zinc around the steel coil or the thickness of the entire double-sided coating.

DX51D material is a mild steel galvanized layer for steel products. Specifically, DX51D is a steel grade characterized by its cold-formed bending and profiling qualities.

G90 refers to the coating type and coating weight on the steel coil. "G" means that the coating is galvanized. Meanwhile, the number "90" represents the weight of zinc on the steel. G90 galvanized steel is hot-dip galvanized cold-rolled steel to improve durability.

Hot-dip galvanizing is one of the effective means to delay the environmental corrosion of iron and steel materials, it is the surface of the cleaned, activated iron and steel products immersed in molten zinc, through the reaction and diffusion between iron and zinc, in the iron and steel products surface plating good adhesion of zinc alloy coating.

AZ stands for aluminum-zinc alloy, which is the material of the steel coating. AZ50 refers to the total weight of both sides of the aluminum-zinc alloy coating in the three-point test in ASTM a972 standard is 0.50 ounces/square foot, which is equivalent to 150 grams/square meter.

AZ55 is the standard for galvanized steel sheets and coils used in a variety of applications, including roofing and siding. The AZ55 name refers to the thickness of the coating on the coil, which is between 0.375 and 1.5mm (0.015 and 0.059 inches).
