Coils are divided into chilled coils and cold rolled coils. The difference between the two is that in appearance, the general chilled coil is slightly black; the surface quality, structure, and dimensional accuracy of the cold-rolled sheet are better than that of the chilled coil; in terms of performance, because the hot-rolled coil goes through the cold rolling process The directly obtained chilled coils undergo work hardening during cold rolling, resulting in an increase in yield strength and some residual internal stress, and the external performance is relatively “hard”, so it is called chilled coils.

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.

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

Gnee steel Supply cold-rolled steel coils, cold-rolled steel plates, cold-rolled steel strips,etc. Welcome friends from all over the world to purchase!

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.

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

Galvanized steel coil refers to rolled coil steel product that has been cleansed and heated before it is dipped into molten zinc. The hot-rolled or cold-rolled steel strip, sheet, or slab can be coated with zinc and iron (GA) or zinc (GI).
