Hot dip galvanized steel plate

Hot dip galvanized steel plate is produced by using hot-rolled steel strip or cold-rolled steel strip as the base plate through a continuous hot-dip galvanizing process, which can prevent surface corrosion and rust of thin steel plates and steel strips.
Those that are cross-cut and supplied as rectangular flat sheets are hot-dip galvanized sheets; those that are rolled and supplied in rolls are hot-dip galvanized sheets.
roll.
Due to the different substrates used, hot-dip galvanized steel sheets can be divided into hot-rolled galvanized sheet coils and cold-rolled hot-dip galvanized sheet coils. They are mainly used in construction, home appliances, automobiles, containers, transportation and household industries. Especially industries such as steel structure construction, automobile manufacturing, and steel plate window manufacturing.

1. Characteristics of hot-dip galvanized steel sheets
Strong corrosion resistance, good surface quality, conducive to deep processing, economical and practical, etc. 2. Classification and symbols of hot-dip galvanized steel sheets
According to the processing performance, it is divided into: general purpose (PT), mechanical engagement (JY), deep drawing (SC), super deep drawing aging (CS), structure (JG);
According to the weight of the zinc layer, the surface of pure zinc is divided into: 100/100 (the weight of the zinc layer is less than 100g/m2), 120/120, 200/200, 275/275, 350/350, 450/450600/600:
Zinc-iron alloy surface is divided into: 90/90
(The weight of the zinc-iron alloy layer is less than 90g/m2), 100/100, 120/120, 180/180;
According to the surface structure, it is divided into: normal zinc flower Z, small zinc flower X, smooth zinc flower GZ, zinc-iron alloy XT;
According to surface quality, they are divided into: Group I (I), Group II (II);
According to dimensional accuracy, it is divided into: advanced precision A, ordinary precision B;
According to the surface treatment, it is divided into: chromic acid passivation L, oil coating Y, chromic acid passivation plus oil coating LY

3. Hot dip galvanizing
Among various coating methods for protecting steel substrates, hot dip galvanizing is an excellent one. It not only coats the steel with a thicker layer of pure zinc, but also forms a zinc-iron alloy layer after going through quite complex physical and chemical reactions while the zinc is in a liquid state. This plating method not only has the corrosion resistance characteristics of electroplated zinc, but also has a zinc-iron alloy layer. It also has strong corrosion resistance that cannot be compared with electroplated zinc. Therefore, this plating method is particularly suitable for various strong corrosive environments such as strong acid and alkali mist.
