Description
Channel steel is a long steel with a groove-shaped cross-section. It is a carbon structural steel for construction and machinery. It is a steel steel with a complex section with a groove-shaped cross-section. Channel steel is mainly used in building structures, curtain wall engineering, mechanical equipment and vehicle manufacturing. Channel steel is divided into ordinary channel steel and light channel steel. The specifications of hot rolled ordinary channel steel are 5-40#. The specifications of hot rolled flexible channel steel supplied by both supply and demand parties are 6.5-30#. Channel steel is mainly used in building structures, vehicle manufacturing, other industrial structures and fixed disk cabinets, etc. Channel steel is often used in conjunction with I-shaped steel. Channel steel can be divided into four types according to its shape: cold-bending equilateral channel steel, cold-bending unequal channel steel, cold-bending inner curling channel steel, and cold-bending outer curling channel steel. According to the theory of steel structure, the channel steel wing plate should be subjected to stress, which means that the channel steel should stand, not lying. Number ① Use international chemical element symbols and domestic symbols to represent chemical components, and use Arabic letters to represent component content: For example: China and Russia 12CrNi3A ② Use fixed digits to represent steel series or numbers; such as: United States, Japan, 300 series, 400 series, 200 series; ③ Use Latin letters and order to form serial numbers, which only represent the purpose. Specifications Settings The specifications of channel steel are mainly expressed by height (h), leg width (b), waist thickness (d), etc. The specifications of domestic channel steel are from 5-40, that is, the corresponding height is 5-40cm. At the same height, light channel steel is narrower than ordinary channel steel legs, thinner waist and lighter in weight. No. 18 -40 is a large channel steel, and No. 5 -16 is a medium channel steel. Imported channel steel indicates actual specifications and dimensions and related standards. The import and export order of channel steel is generally determined after the corresponding carbon junction steel (or low alloy steel) steel number is mainly based on the specifications required during use. Apart from specifications, channel steel has no specific composition and performance series. The delivery length of channel steel is divided into two types: fixed ruler and double ruler, and the tolerance value is specified in the corresponding standards. The length selection range of domestic channel steel is divided into three types: 5 -12m, 5 -19m, and 6 -19m according to the specification number. The length selection range of imported channel steel is generally 6-15m.
