GI galvanized steel 0.2mm thick cold rolled galvanized coil

The process of cold rolling increasing the SGCC DX51D ZINC Cold rolled coil’s strength and hardness, while decreasing its ductility.

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.

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 Customize Cold Rolled Galvanized Steel Coil Hc220bd 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.

ASTM Cold Rolled Dipped GI Galvanized Steel Coil GI Strip Coil is hot-rolled steel that has been cleaned of iron oxide scale (pickled) and reduced to a specific thickness through a series of rolling stands (tandem mill) or passed back and forth through a reversing rolling mill. The steel can be heated to controlled temperatures (annealing) depending on mechanical property requirements, and final rolled to the desired thickness.

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 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. Usually, hot-dipped galvanized steel sheet and galvanized steel coil process and specifications are basically the same.

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

z180 z275 z350 Galvanized Steel Coil Cold Rolled coil has Lowest Long Term Cost – invariably more cost effective in the long term because it lasts longer and needs less maintenance.Reliability – Coating life and performance are reliable and predictable.

cold rolled high quality Galvanized Steel Coil is also used to make wrought iron gates and other items,high tension electrical towers, protective gears, highway signs,make metal pails,build houses,etc.

Ral7016 Dx51d PPGI Gi cold rolled Steel Coil is produced through a process of metal coating which involves passing cold rolled coils through a zinc pot. The process ensures the adherence of zinc to the surface of steel sheet.The zinc layer provides excellent corrosion resistance so that it can prolong the service life of the product.
