Zhongtang Iron And Steel (Shandong) Group Co.,Ltd. is a well-known color coated plate company, the company integrity management, to ensure the quality of color coated plate, the following talk about the difference between hot galvanized plate and cold galvanized plate:

1, hot galvanized sheet generally thicker zinc layer, about 10um or more, strong anti-corrosion ability. So it is a commonly used galvanizing process. The electrogalvanizing is very thin, about 3-5um, the hot plating surface is rough, bright, and there are zinc flowers in severe cases, and the electroplating is smooth and gray (dirty). The galvanized steel plate made by electroplating has good processing properties

2, the chemical industry general galvanizing more, suitable for small parts; Hot galvanized sheet is generally used in power equipment and components, suitable for large components and equipment.

3, hot galvanized sheet and electrogalvanized sheet in the amount of galvanizing has a great difference. The galvanizing amount of hot galvanized sheet can not be too small, generally the minimum is 50-60g/m2 on both sides, and the maximum is 600g/m2.

4, hot galvanized sheet and electrogalvanized sheet have fundamental differences in the coating structure. There is a slightly brittle compound layer between the pure zinc coating and the steel strip substrate, and the pure zinc coating mostly forms zinc flowers when crystallized, and the coating is uniform without pores.

5, hot galvanized sheet and electrogalvanized sheet heat treatment process is also completely different, hot galvanized sheet is generally cold hard plate as raw material, continuous annealing and hot galvanized sheet in the galvanizing line, steel strip in the short time after heating and cooling, so the strength and plasticity are affected to a certain extent, its stamping performance than the same cold hard plate after professional production line degreasing annealing cold rolled plate poor.
