Galvanized steel plate is a welded steel plate with hot dip plating or electric galvanized layer on the surface, which is generally widely used in construction, home appliances, vehicles and vessels, container manufacturing, electromechanical industry and so on.
Name：Galvanized steel sheet
Applications: vehicle and ship, container manufacturing, electromechanical industry, etc
Definition: Welded steel plates with hot dip or electrogalvanizing surfaces
classify：
一、Galvanized steel plate is divided into ordinary electrolytic plate and fingerprint resistant electrolytic plate. The fingerprint resistant plate is added to the ordinary electrolytic plate on the basis of a fingerprint resistant treatment, can resist sweat, generally used in the parts without any treatment, the brand is SECC-N. Ordinary electrolytic plate and phosphating plate and passivation plate, phosphating is more commonly used, the brand is SECC-P, commonly known as p material. Passivated plates can be oiled or unoiled.
Hot dip zinc steel plate (SGCC) has one advantage over electric galvanized steel plate (SECC), SECC bending and cross section is very easy to rust, SGCC is much better! High-quality chassis usually use SECC or SGCC galvanized steel plate, the use of this material chassis steel plate color bright, metallic luster, the advantage of this steel plate is good corrosion resistance.
Electric galvanized steel plate (SECC): uniform gray, mainly imported, fingerprint resistance, has very superior corrosion resistance, and maintains the processability of cold rolled sheet.
Hot dip zinc plate (SGCC): dip plated, bright white, small zinc flowers, main characteristics: corrosion resistance; Lacquerability; Formability; Spot weldability. Use: Extremely extensive, small household appliances, good appearance, but compared with SECC, its price is more expensive.
二、Divided by zinc, the size of zinc flowers and the thickness of zinc layer can indicate the quality of zinc plating, and the smaller and thicker the better. There is also the possibility to distinguish by its coating: such as Z12 indicates the total amount of double-sided coating 120g/mm.
Aluminized zinc steel plate (SGLD): It is a multiphase alloy material containing rich aluminum and zinc.
Because of the characteristics of aluminum and zinc, it has better performance than hot dip zinc steel plate (SGCC). Main features: corrosion resistance, which is much higher than SGCC; Heat resistance; Heat conduction and heat reflection; Formability; Weldability. Uses: Used in some places that require good reflection, such as the reflector plate inside the oven, the reflector plate of the electric pot. Hot dip zinc steel plate (SGCC) is general use, aluminized zinc steel plate (SGLD) is deep stamping, SGCE is super deep stamping.
