冷拉钢生产厂家将冷拉型钢分为简单断面型钢和复杂断面型钢两种，冷拉钢按照断面的形状。前者包括了冷拉方钢、冷拉扁钢、冷拉圆钢和冷拉角钢、冷拉六角钢等，满足不同领域对型钢的使用要求。
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.
冷拉方钢是方形断面的冷拉型钢，边长为3-100mm；冷拉圆钢是断面为圆形的钢材，除了冷拉方式之外，还可以通过热轧、锻制等工艺制作圆钢，但得到产品性能是不同的比如说热轧圆钢的直径多为5-250mm；锻制圆钢的直径较粗，多用作轴坯；而冷拉圆钢的直径为3-100mm尺寸相对来说较高。冷拉扁钢宽12-300mm厚4-60mm截面多为长方形且带有一点纯边。
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.
冷拉扁钢一般可作为废品钢材，也可以用作焊管的坯料和叠轧薄板用的薄板坯。用途上，冷拉扁钢可以用于制箍铁、机械零件和工具，房架结构件和扶梯也可以。冷拉角钢从外形结构上区分的话有等边角钢和不等边角钢两种，一般冷拉角钢的规格用边长和边厚的尺寸表示，例如规格为2-20号，即边长的厘米数。所以产品所表现出的优异性也是一样的用户可以根据自身的要求和条件来选择所需的冷拉型钢，使其自身的价值能够得到充分发挥，型钢的使用寿命也能得以延长。
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.
