Cold-drawn steel manufacturers divide cold-drawn steel into two types: simple-section steel and complex-section steel. Cold-drawn steel follows the shape of the section. The former includes cold-drawn square steel, cold-drawn flat steel, cold-drawn round steel and cold-drawn angle steel, cold-drawn hexagonal steel, etc., which meet the requirements for the use of section steel in different fields.
Cold-drawn square steel is a cold-drawn steel with a square cross section, with a side length of 3-100mm. Cold-drawn round steel is a steel with a round cross-section. In addition to the cold-drawn method, it can also be produced by hot rolling, forging and other processes. Round steel, but the product performance is different. For example, the diameter of hot-rolled round steel is mostly 5-250mm; the diameter of forged round steel is relatively thick, and it is mostly used as the shaft billet; and the diameter of cold-drawn round steel is 3-100mm. Relatively high. Cold-drawn flat steel is 12-300mm wide and 4-60mm thick with a rectangular cross section and a little pure edges.
Cold-drawn flat steel is generally used as scrap steel, and it can also be used as a blank for welded pipes and a thin slab for laminated sheets. In use, cold-drawn flat steel can be used to make hoop irons, mechanical parts and tools, as well as housing frame components and escalators. There are two types of cold-drawn angle steel: equilateral angle steel and unequal-angle angle steel. The specifications of cold-drawn angle steel are expressed by the length and thickness of the side. For example, the size is 2-20, which is the cm of the side length. number. Therefore, the excellent performance of the product is also the same. Users can choose the required cold-drawn steel according to their own requirements and conditions, so that their own value can be fully exerted, and the service life of the steel can be extended.
