Galvanized steel plate/sheet refers to a type of steel plate or sheet that has been coated with a layer of zinc. This process is known as galvanization. The main method used is hot dip galvanizing or subjected to an electrochemical process to apply the zinc coating.

Z100 galvanized steel sheet refers to a specific type of galvanized steel sheet with a coating weight of 100 grams per square meter. The Z100 designation indicates the amount of zinc coating applied to the steel, with a higher number representing a thicker and more durable coating.

S350GD/S450GD is a grade of galvanized steel plate or steel material defined according to the European standard EN 10346. S350GD has a minimum yield strength of 350 MPa.,S450GD has a minimum yield strength of 450 MPa.

SPCC (Steel Plate Cold Rolled Commercial) is a common grade for galvanized steel sheets. It refers to a cold-rolled steel sheet that is coated with a layer of zinc to provide corrosion resistance and improve durability.

Z275 galvanized steel sheet refers to a specific type of galvanized steel sheet with a coating weight of 275 grams per square meter. The Z275 designation indicates the amount of zinc coating applied to the steel, with a higher number representing a thicker and more durable coating.

Similar to DX51D, DX55D has a higher yield strength, which means it has higher strength and load-bearing capacity. This makes it suitable for applications that require higher strength.

The yield strength of DX53D is 53000 psi or 365 MPa. This means that DX53D has a higher yield strength compared to DX51D, indicating that it is stronger and has a greater load-bearing capacity.

The yield strength of DX52D is 52000 psi or 360 MPa. This indicates that DX52D has a lower yield strength compared to DX53D. However, it is still a strong and durable material suitable for various applications in construction, manufacturing, and automotive industries.

DX51D refers to the coating quality of the galvanized steel sheet. The “D” represents the deep drawing quality, indicating that the steel is suitable for deep drawing applications. The “X” indicates that the steel is continuous hot-dip galvanized. The number “51” indicates the minimum yield strength of the steel, which is 51,000 psi or 355 MPa.
