Cold Rolled Steel Galvanized Hot-selling steel coil

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 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.

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.

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.

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.

The mechanical engineering workshops of our factory are all equipped with numerical central control ,Our factory has been constantly improving the platform construction, improving the quality of technical team, strengthening the invention of products category, formed complete R & D system and production quality management system, wined high reputation in the iron and steel industry.

Cold-rolled strips are widely used, such as automobile manufacturing, electrical products, rolling stock, aviation, precision instruments, canned food, etc. Cold-rolled sheet is the abbreviation of ordinary carbon structural steel cold-rolled sheet, also known as cold-rolled sheet, commonly known as cold-rolled sheet, and sometimes mistakenly written as cold-rolled sheet.

Cold rolled coil could supply better control of thickness, shape, width, surface finish, and other special quality features that compliment the emerging need for highly engineered end uses. Take construction projets for example: steel sheds, industrial buildings, and garages.
