![]() It is a general term for stainless acid-resistant steel, which resists corrosion from atmospheric, acid, alkali, salt, and other media. Can be added with anti-fingerprint coating Price Expensive Cheap Stainless Steel Max material thickness Common material thickness can be seen 0.6-1.5mm Corrosion resistance Thin coating, poor The plating is thick and good. Mechanical performance Same as the base metal After annealing, it has age hardening the material is soft. Plating organization Pure zinc coating The outermost layer is pure zinc and the inner layer is iron-zinc alloy. Solidified structure of zinc layer, may have zinc spangle or not. Electro-galvanized sheet (EG/SECC) Hot-dipped metallic-coated sheet (GI) Base metal Cold rolled annealed steel Cold rolled hard steel plate Pre-treatment Electroplating Hot dip Zinc plating Hard plating for thick Hard plating for thin Plating surface The zinc layer is adsorbed on the surface of the steel, and the surface is smooth and free of zinc spangle. Let’s compare the above two galvanized sheets of steel through a table. Galvanized steel can be mainly divided into: Types of Sheet MetalĬommonly used sheet metal materials can be divided into two categories, which are: The defining characteristic of sheet metal is that it has the same thickness throughout a part. According to a professional journal, it can be described as a comprehensive cold working process for metal sheets, usually less than 6mm, which includes techniques such as shearing, punching/cutting, folding, riveting, splicing, and forming (such as car body). Sheet metal is a processing technology that does not have a clear definition yet. Mechanical properties of metals everyone must know.
