primarily cold coil

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.

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.

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.

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.

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 rolled zinc coated g120 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.

Galvanized steel coil, immersing the thin steel plate in the molten zinc bath, and adhering a layer of zinc thin steel plate on the surface. It is mainly produced by the continuous galvanizing process, that is, the coiled steel plate is continuously immersed in the zinc-melted plating tank to make galvanized steel plate; alloyed galvanized steel plate. This kind of steel plate is also made by the hot-dip method, but it is heated to about 500 °C immediately after exiting the tank to form an alloy film of zinc and iron. This galvanized steel coil has good paint adhesion and weldability.

Cold-rolled steel coils are made of hot-rolled coils and rolled at room temperature below the recrystallization temperature. Cold-rolled steel has good performance. That is, cold-rolled steel can be thinner and more precise.
