The national standard of C channel is GB/T6725. The material is Q195 and Q235B galvanized. The standard length is 6 meters. Its specifications are expressed as section height Hx section width Bx curling width Cx thickness T. The specifications are C80x30x12x2, C80x40x15x2.5, C100x40x15x2, C100x50x15x2.5, C120x40x15x2, C120x50x15x2.5, C140x50x20x2, C140x50x20x2.5, etc.
C channel is made of high-strength steel plate, which is cold-bent and rolled. It has uniform wall thickness, high rolling strength, good bending and compression resistance, good straightness, high degree of automation, and quick and convenient installation. Although the cross-sectional dimensions of C-channel are light, they are very consistent with the stress characteristics, so that the effectiveness of steel can be fully utilized, and the specifications and dimensions are determined according to needs. Using C-channel can reduce the weight of building roofs, reduce steel consumption, and is economical and efficient. It is a new type of building material that replaces angle steel, channel steel, steel bars, etc. The product can be used as the main load-bearing structure of large and medium-sized industrial and civil buildings, such as roof load-bearing and wall support of factories, warehouses, motorcades, hangars, exhibition halls, theaters, stadiums, and market flower sheds.
C-shaped steel channels are widely used in aprons and wall beams of steel structure buildings, and can also be combined into light roof trusses, brackets and other building components. In addition, it can also be used for mechanical light industry to manufacture columns, beams, arms, etc.
