Square steel: It is solid, bar material. Different from square tubes, hollow tubes belong to pipe materials. Steel: refers to the various shapes, sizes, and properties of steel ingots, billets, or steel produced through pressure processing. Steel is an essential material for national construction and the realization of the Four Modernizations. It is widely used and has a wide variety of varieties. According to the different cross-sectional shapes, steel is generally divided into four categories: profiles, plates, pipes, and metal products. In order to facilitate the organization of steel production, ordering and supply, and to do a good job in business management, it is further divided into heavy rail, light rail, large section steel, medium section steel, small section steel, cold-formed steel, high-quality section steel, wire rod, medium thick steel plate, thin steel plate, electrical silicon steel sheet, strip steel, seamless steel pipe steel, welded steel pipe, metal products and other varieties.
