Channel steel is a carbon structural steel for construction and machinery. It is a section steel with complex cross-section. The cross-sectional shape is channel-shaped.
Channel steel is mainly used in building structures, curtain wall engineering, mechanical equipment and vehicle manufacturing. It is required to have good welding, riveting performance and comprehensive mechanical properties in use. The raw steel slabs for producing channel steel are carbon-bonded steels or low-alloy steel slabs with a carbon content not exceeding 0.25%. The finished channel steel is delivered by hot working forming, normalizing or hot rolling.
The specifications of channel steel mainly use dimensions such as height (h), leg width (b), and waist thickness (d).
Said that the current domestic channel steel specifications range from 5-40, that is, the corresponding height is 5-40cm.
At the same height, light channel steel has narrower legs, thinner waist and lighter weight than ordinary channel steel. Correspondingly, the prices of light channel steel and ordinary channel steel manufacturers are also different. No. 18-40 is a large channel steel, and No. 5-16 is a medium-sized channel steel.
The delivery length of channel steel is divided into two types: fixed-scale and double-scale. The length selection range of domestic channel steel is divided into 5-12m, 5-19m, 6-19m according to different specifications. The length of imported channel steel is generally 6-15m.
The allowable deviation of the surface quality and geometry of the channel steel is specified in the standard. Generally, the surface must be free from harmful defects, and there must be no significant twisting. The allowable value of wave bending (scythe bending) of channel steel and the relevant parameters (h, b, d, t, etc.) of the shape of the channel steel surface are specified. Value, tolerance value. The main manifestations of incorrect channel geometry are: angle, leg extension, and leg parallelism.
