cold rolled galvanized steel coil HC300LAD+Z

g20 cold rolled high quality Galvanized Steel 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

High quality cold rolled steel coil full hard Galvanized steel coil is processed from hot-rolled sheets at room temperature. Although the temperature of the steel sheet will be heated during the processing, it is still called cold-rolled. Due to the continuous cold deformation of hot rolling, the mechanical properties are relatively poor and the hardness is too high.

Cold-rolled steel coil is better in surface quality (such as Surface roughness) than hot plate because it is obtained by cold rolling and some surface finishing is carried out at the same time. Therefore, if the product after the sequence of painting, such as coating quality, there are higher requirements, the general choice of the cold plate. The hot plate is divided into the pickling plate and the unpickling plate.

Galvanized steel coil has a wide range of applications, and its advantage is that it has a long anti-corrosion period. It is mainly used for home appliances, office panels, roof sheets, automotive panels, construction and substrate of prepainted steel coils.

Galvanized coil products are mainly used in construction, light industry, automobile, agriculture, animal husbandry, fishery, commerce and other industries. The construction industry is mainly used to manufacture anti-corrosion roof panels and roof grilles of industrial and civil buildings; The light industry uses it to manufacture household appliance shells, civil chimneys, kitchen appliances, etc.

Cold-rolled sheet in coil form is produced by removing rust from hot-rolled sheet by “pickling” it in a weak acid solution, then washing, brushing, drying, oiling and unrolling the sheet and finally performing cold-rolling by passing the sheet through a reducing mill under pressure and winding it into a roll.

This product is based on cold -rolled steel strip as substrate,after continuous hot-dip galvanizing process and produced products.It is an excellent resistance to atmospheric corrosion of coated steel,cold-rolled sheet coil after the galvanized can extend the service life for 15-20 years.

Good Quality Cold Rolled Steel zinc Coil is mainly used in the construction of household appliances, automobile containers, especially steel structure building, automobile parts, steel plate warehouse manufacturing and other industries. Their characteristics are mainly: strong corrosion resistance, good surface quality, economic and practical.

Cold Rolled zinc Steel Sheet steel coil Galvanized Steel Sheet is defined as a carbon steel sheet coated with zinc on both sides.

Compared with hot rolled steel plate, Galvanized steel Ss400 cold rolled steel coil thickness is more accurate, and the surface is smooth, beautiful, but also has a variety of superior mechanical properties, especially machining performance.

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 a kind of steel coil that immersed in the dissolved zinc bath to adhere to the surface with a layer of zinc. At present, the main method is to make galvanized steel coil be dipped in a bath with dissolved zinc.
