Product parameters

Cold rolled steel is the steel produced by cold rolling, under certain conditions, the steel plate can be further pressed into the required thickness, it and hot pressed steel plate compared, the thickness will be more accurate, and the surface is more smooth and more beautiful. At the same time, it also maintains stable performance, such as processing skills are very good, but they are not suitable for processing, so they need to be handed over to customers by annealing.

Cold-rolled steel sheet is the abbreviation of ordinary carbon structural steel cold-rolled sheet, also known as cold-rolled sheet, commonly known as cold plate, sometimes mistakenly written as cold tie plate. Cold plate is made of ordinary carbon structural steel hot rolled steel strip, after further cold rolling to make a thickness of less than 4mm steel plate. Because it is rolled at room temperature, no oxide sheet is produced, so the cold plate surface quality is good, the dimensional accuracy is high, coupled with annealing treatment, its mechanical properties and process properties are better than hot rolled thin steel plate, in many fields, especially in the field of home appliance manufacturing.

St37 is a German brand, but it is a general brand, and there are several smaller brands.

For example, St37-2 St37-3U St37-3n RSt-2 USt37-2 and so on.
