1. Cold-drawn sheet: It is a product made of hot-rolled coil at room temperature below recrystallization temperature.

2. Galvanized sheet: refers to a steel plate with a layer of zinc on its surface.

Second, the characteristics are different.

1. Cold-drawn sheet: due to no heating, there are no defects such as pockmarks and iron scales that often appear in hot rolling, and the surface quality is good and the finish is high. Moreover, the dimensional accuracy of cold-rolled products is high, and the properties and microstructure of products can meet some special requirements, such as electromagnetic properties and deep drawing properties.

2. Galvanized sheet: Due to the different treatment methods in the coating process, the surface state of galvanized sheet is also different, including ordinary zinc flower, fine zinc flower, flat zinc flower, zinc-free flower and phosphating surface. German standards also stipulate the surface level.

Third, the use is different.

1, cold-rolled sheet: mostly used in automobile manufacturing and electrical products.

2. galvanized sheet: mainly used in construction, light industry, automobile, agriculture, animal husbandry, fishery and commerce. Among them, the construction industry is mainly used to manufacture corrosion-resistant roof panels and roof grilles for industrial and civil buildings; Light industry uses it to make household appliance shells, civil chimneys, kitchen utensils and so on.
