Az150 ASTM A792m Building Material Galvanized Coated Galvalume Steel Coil

GI galvanized steel coil z275 zinc sheet metal steel coil(GI) is produced by passing the Full Hard sheet which has undergone the acid washing process and rolling process through the zinc pot, thereby applying zinc film to the surface. It has excellent corrosion resistance, paintability, and workability due to Zinc’s characteristics.

Cold-rolled coils are a steel product produced by applying plastic deformation to hot-rolled steel on cold-rolling mills. With such processing, the product can have more accurate dimensional tolerances, better surface quality and improved mechanical properties as compared with hot-rolled coils. Cold rolling is also used to make thinner coils than hot-rolling mills can currently produce (less than 0.8-1.0 mm).

Galvanized Steel coil is produced through applying Zn coat on both faces by hot dip process. It enjoys both the physical protective feature and the electrochemical protective property of Zn.

Galvanized steel coil, also known as galvanized coil, is a galvanized coil product. Galvanized coil, a steel material coated with zinc. The galvanized coil is the predecessor of the galvanized sheet. The galvanized coil is cut into sheets by equipment. The galvanized coil is placed on the shelf with a forklift or aerial crane, and then transferred, flattened and cut by the equipment.

For galvanized steel coils, the steel sheet is immersed in a molten zinc bath to make a sheet of zinc coated on its surface. It is mainly produced by continuous galvanizing process, that is, the rolled steel plate is continuously immersed in a plating tank with zinc melted to make galvanized steel plate; alloyed galvanized steel plate.

Cold coil is made of hot rolled coil at room temperature and below the recrystallization temperature, including plate and coil, of which the sheet delivered is called steel plate, also known as box plate or plate; the long length and delivered in coil is called steel strip, also known as coil plate.

Using hot-rolled steel coil as raw material, after pickling to remove oxide scale, cold continuous rolling is carried out, and the finished product is rolled hard coil. The cold work hardening caused by continuous cold deformation increases the strength, hardness and toughness and plastic index of rolled hard coil.

Galvalume Coil composition by weight ratio of 55% aluminum,43.4% zinc,1.6% silicon, at high temperature 600 high temperature solidification and aluminized zinc plate surface is a unique smooth flat gorgeous star flower, the base color is silver white special coating structure makes it has excellent corrosion resistance

Cold-rolled galvanized sheet is a kind of galvanized steel sheet. Steel sheets are classified into two types: hot-rolled and cold-rolled. Cold-rolled sheet is flat, rectangular, and can be directly rolled. Cold rolling is a steel sheet in which the steel sheet is further thinned to a target thickness at room temperature.
