Product description:
Channel steel is a long steel with a grooved section, which belongs to carbon structural steel for construction and machinery. It is a steel with complex section, and its section shape is grooved. Channel steel is mainly used for building structure, curtain wall engineering, mechanical equipment and vehicle manufacturing.
Channel steel is divided into ordinary channel steel and light channel steel. The specification of hot rolled ordinary channel steel is 5-40 #. The specification of hot-rolled flexible channel steel supplied through agreement between the supplier and the buyer is 6.5-30 #. Channel steel is mainly used for building structures, vehicle manufacturing, other industrial structures and fixed panels and cabinets, etc. channel steel is often used with I-beam.
The channel steel can be divided into four types according to its shape: cold-formed equal edge channel steel, cold-formed unequal edge channel steel, cold-formed inner curling channel steel and cold-formed outer curling channel steel.
According to the theory of steel structure, it should be the channel steel wing plate.
Channel steel is a new type of economical construction steel. The section style of channel steel is economical and suitable, with good mechanical function. During rolling, the extension of each point on the section is relatively balanced, and the internal stress is small. Compared with the general I-shaped steel, it has the advantages of large section modulus, light weight and metal saving, and can reduce the construction structure by 30-40%. Because the inner and outer sides of its legs are parallel and the leg ends are right angles, the riveting work can be saved 25% by assembling and assembling parts It is often used for large-scale construction (such as factory buildings, high-rise buildings, etc.) with large cross-section and good cross-section invariability, as well as bridges, ships, lifting and transportation machinery, foundation, supports, and foundation piles.
Channel steel is a kind of economical section steel optimized and developed from I-shaped steel with double superior section mechanical function. Its characteristics are as follows: wide flange, large lateral stiffness, strong bending resistance, and two surfaces of flange are parallel to each other, making the connection, processing and assembly light. Compared with welded I-beam steel, it has low cost, high accuracy, small residual stress, no need for noble materials and weld survey, and saves about 30% of the construction cost of steel structure. Under the same section load, the component of hot rolled H steel structure is 15% - 20% less than that of ancient steel structure. Compared with the concrete structure, the hot-rolled H steel structure can increase the operating area by 6%, while the self weight of the structure can be reduced by 20% - 30%, reducing the design internal force of the structure.
