SGCC Bending G450 Z275 Galvanized Steel Coil 1mm Thickness

  Hot-dip galvanized steel (SGCC): dip-plated, bright white, small spangles, it is actually difficult to see the spangles, the big spangles can clearly see the hexagonal pattern, and there is no steel factory in China that can Produce high-quality materials, mainly imported from abroad, Taiwan has chinasteel, shengyu steel corporation two can produce.Main features: corrosion resistance; paintability; formability; spot weldability. Uses: It is very wide, small household appliances, good appearance, but compared with SECC, its price is a bit more expensive, many manufacturers switch to SECC to save costs.

  Divided by zinc, the size of the spangle and the thickness of the zinc layer can indicate the quality of galvanizing, the smaller the thickness, the better. Of course, don't forget to let the manufacturer add fingerprint resistance. It is also possible to distinguish by its coating: for example, Z12 means the total amount of double-sided coating is 120g/mm. E.g:

  Galvalume steel (SGLD): It is a multi-phase alloy material that contains rich aluminum and zinc. Because of the characteristics of aluminum and zinc, it has better performance than hot-dip galvanized steel (SGCC).Main characteristics: corrosion resistance, its ability is much higher than SGCC; heat resistance; heat conduction and heat reflectivity; formability; weldability. Uses: used in some places that require good reflectivity, such as the reflector inside the oven, The reflector of the electric cooker.Taiwan's Shengyu Steel Corporation can produce it. There is no steel mill that can produce it in China. The price is much more expensive than SGCC. Hot-dip galvanized steel (SGCC) is for general use, aluminum-galvanized steel (SGLD) is for deep drawing, and SGCE is for ultra-deep drawing.
