There are many types of steel structure steels, commonly used including H – beam, I – beam, Z – beam, C – beam 4 categories.
H – beam steel is a new economic construction steel. H section shape economic and reasonable, good mechanical properties, rolling point on the cross section of the extension of uniform, small internal stress, compared with ordinary I steel, has the advantages of large section modulus, light weight, save metal, can reduce the building structure 30-40%; And because its legs are parallel inside and outside, the leg end is a right Angle, assembling and combining components, can save welding, riveting work up to 25%. It is often used for large buildings (such as factories, high-rise buildings, etc.) requiring large bearing capacity and good cross-section stability, as well as Bridges, ships, lifting and transportation machinery, equipment foundation, supports, foundation piles, etc. H beams are divided into hot rolled H beams and welded H beams.
I-steel, also known as steel beam, is a long steel strip with i-shaped section. I – steel ordinary I – steel and light I – steel. I steel is widely used in various building structures, Bridges, vehicles, supports, machinery and so on. Ordinary I-steel and light I-steel wing reason root gradually thin to the edge, there is a certain Angle, ordinary I-steel and light I-steel model is represented by its waist height cm number of Arabic numerals.
Z-shaped steel is a common cold-formed thin-wall steel, the thickness is generally between 1.6-3.0mm, the section height is mostly between 120-350mm. Processing materials for hot rolling (paint), galvanized. Z – section steel is usually used in large steel structure plant. Processing length and hole according to processing requirements. Z steel supporting products: color steel tile; Rock wool sandwich board; Floor bearing plate, etc.
The types of C-section steel are: galvanized C-section steel, hot galvanized C-section steel, inner beveled C-section steel, roof purlin C-section steel, automotive profile C-section template support C-section steel, equipment with precision C-section steel, etc. It is made of hot coil plate and cold bending, with thin wall and light weight, excellent section performance and high strength. Compared with traditional channel steel, 30% material can be saved with the same strength. Widely used in steel structure building purlin, wall beam, can also be combined into light weight roof truss, bracket and other building components. In addition, it can also be used in the mechanical light manufacturing of the column, beam and arm.
