Q355b national standard H-section steel, 594 * 302 * 14 low alloy H-section steel, one for sale

  British standard H-section steel, American Standard H-section steel, European standard H-section steel, European standard channel steel and European standard I-beam are a new type of steel for economic construction
The section shape of H-section steel is economical and reasonable, with good mechanical properties
During rolling, each point on the section extends evenly and the internal stress is small
Compared with ordinary I-section steel, H-section steel 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 25% of the workload of welding and riveting
It is often used in large buildings (such as plants, high-rise buildings, etc
) with large bearing capacity and good cutting sprouting quality, as well as bridges, ships, hoisting and transportation machinery, equipment foundation, supports, foundation piles, etc
