1. C-shaped steel
They are all processed by hot coil and cold bending, and are automatically processed by C-shaped steel forming machine. With thin wall and light weight, excellent section performance and high strength, the same strength can save 30% of material compared with traditional channel steel.
C-shaped steel purlins are divided into five specifications according to their height: 80, 100, 120, 140 and 160. The length can be determined according to the engineering design, but considering the conditions of transportation and installation, the total length is generally not more than 12 meters. C-shaped steel is widely used in purlins and wall beams of steel structures, and can also be assembled into lightweight roof trusses, brackets and other building components. In addition, it can also be used for columns, beams and arms in mechanical light industry manufacturing.
2. I-shaped steel
It is called steel beam, which is a long strip of steel with I-shaped section. Its specification is expressed in millimeters of waist height (h) * leg width (b) * waist thickness (d). For example, "I 160 * 88 * 6" means I steel with waist height of 160 mm, leg width of 88 mm and waist thickness of 6 mm. I-beam is divided into ordinary I-beam, light I-beam and H-beam.
The flange of ordinary I section steel and light I section steel gradually thins from the root to the edge, with a certain angle. Because their section size is relatively high and narrow, the moment of inertia of the two main sleeves of the section is relatively different. Therefore, it is generally only used for members bent in the web plane or to form a lattice load-bearing member. It is not used for axial compression members or members with bending perpendicular to the plane of the web, which is a great limitation in its application.
Jinan section steel manufacturer reminded that I-beam is widely used in various building structures, bridges, vehicles, supports, machinery, etc.
3. H-shaped steel
It is a kind of economical section steel with better section mechanical properties, which is optimized and developed from I-section steel, especially the section is the same as the English letter "H". H-shaped steel is divided into, wide flange H-shaped steel (HW), middle flange H-shaped steel (HM), narrow flange H-shaped steel (HN), thin wall H-shaped steel (HT) and H-shaped steel (HU).
H-shaped steel is a new type of economical construction steel. The section shape of H-shaped steel is economical and reasonable, and its mechanical properties are good. When rolling, the extension of each point on the section is relatively uniform, and the internal stress is small. Compared with ordinary I-shaped steel, it has the advantages of large section modulus, light weight, and metal saving, which can reduce the building structure by 30-40%; Because the inner and outer sides of its legs are parallel, and the leg ends are right angles, it can be assembled into components, which can save up to 25% of the welding and riveting workload. It is often used for support and foundation pile in large buildings with large bearing capacity and good section stability.
