ASTM A653 5mm Galvanised Steel Plate S220GD S250GD S280GD 100mm-120mm Width

0.18mm-20mm Thick Galvanized Steel Sheet 2mm Thick Cold Rolled/Hot Rolled

(1) surface state: The surface state of galvanized sheet is different because of the different treatment methods in the coating and plating process, such as ordinary zinc flower, fine zinc flower, flat zinc flower, zinc free flower and phosphating surface. The German standard also provides for surface grades.

(2) Galvanized plate should have a good appearance, shall not have harmful defects to the use of the product, such as no plating, holes, cracks and scum, more than thick plating, abrasion, chromic acid dirt, white rust, etc. Foreign standards are not very clear about the specific appearance defects. Some specific defects should be specified in the contract when ordering.

1. Non-alloy hot dip galvanized steel strip:

DC5XD series: can be used for general use, also can be used for deep punching and biting. The higher the zinc content on the surface, the better the anti-corrosion performance; The less galvanized the surface, the better the processing performance.

SXXXGD series: can be used for structure, it has good processing performance and corrosion resistance.

HXXXPD+Z series: including low alloy steel, phosphorous steel and hardened steel, which has excellent machining performance and corrosion resistance.

2. Alloyed hot-dip galvanized steel strip:

DCXXD+ZF series: can be used for structure, stamping and cold forming. Galvanized sheet of this kind of material has better welding performance and coating performance, but it is very easy to produce peel in the process of processing.
