Galvanized plate products are mainly used in construction, light industry, automobile, agriculture, animal husbandry, fishery and commercial industries. The construction industry is mainly used for the manufacture of anti-corrosion industrial and civil building roof panels, roof grids, etc. The light industry uses it to manufacture household appliance shell, civil chimney, kitchen utensils, etc., and the automobile industry is mainly used to manufacture corrosionproof parts of cars. Agriculture, animal husbandry and fishery are mainly used as food storage and transportation, meat and aquatic products frozen processing equipment, etc. Commercial mainly used as material storage and transportation, packaging tools, etc.

Galvanized sheet coil, the thin steel plate is immersed in the melted zinc groove, so that the surface adhesion of a layer of zinc sheet steel. It is mainly produced by continuous galvanizing process, that is, the rolled steel plate is continuously dipped in the melting zinc bath to make galvanized steel plate; Alloyed galvanized steel plate. This steel plate is also made by hot dipping, but immediately after it is out of the groove, it is heated to about 500℃ to create an alloy coating of zinc and iron. This galvanized coil has good coating tightness and weldability.

〣Designation of grades of galvanized steel coils and strips

Common brands are DX51D+Z, DX52D+Z, DC51D+Z, DC52D+Z, S350GD+Z and so on. The grade of galvanized steel plate or steel strip is composed of five parts: product use code, steel grade code, steel type characteristics, hot dip galvanized code (D), +, and total type code of coating. The specific grade naming method is as follows:

A) Galvanized sheet for cold forming:

Brand examples: DX51D+Z(or ZFAZ), DC51D+Z(or ZFAZ), DD52D+Z (or ZFAZ) DX: the bit letter D represents the flat steel for cold forming, the second letter if X, represents the rolling state of the substrate is not specified; If the second letter is C, it means that the substrate is cold rolled. If the second letter is D, it means that the substrate is specified as a hot-rolled substrate.

51~57: two-digit number indicates steel grade number; A D after two digits is the code name of hot dip galvanizing;

Z represents pure zinc plating, ZF represents galvanized iron alloy and AZ represents aluminum-zinc plating.

So: DX51D+Z means that the product is used for cold forming, flat steel, not specified substrate state, steel grade serial number 51, pure zinc coating, hot plating products.

B) Examples of naming other galvanized brands

S350GD+Z: S represents structural steel, 350 represents the prescribed small yield strength of 350Mpa, and G represents steel type

Characteristics are not specified, D indicates hot dip galvanizing, +Z indicates zinc coating.

HX340LAD+ZF: indicates that the product is used as a high strength flat steel for cold forming. The state of the substrate is not specified, and the small yield strength is specified as 340Mpa. The steel type is high strength and low alloy steel, zinc-iron alloy coating, or hot plating. HC340/590DPD+Z: indicates that the product is used for cold forming, high strength flat steel, the specified substrate is cold rolled substrate, the specified small yield strength is 340Mpa, the specified small tensile strength is 590Mpa, the steel type is dual-phase steel, hot plated with pure zinc coating.
