There are many types of steel structure metal, commonly used include H-beam, I-beam, Z-beam, C-beam 4 categories.
H-beam is a new type of economical construction steel. The section shape of H-beam 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-beam, it has the advantages of large section modulus, light weight and metal saving, which can make buildings The structure is reduced by 30-40%; because the inside and outside of the legs are parallel, and the legs are at right angles, they can be assembled into components, which can save welding and riveting workload by 25%. It is often used in large buildings (such as workshops, high-rise buildings, etc.) that require large bearing capacity and good section stability, as well as bridges, ships, lifting and transportation machinery, equipment foundations, supports, foundation piles, etc. H-beams are divided into two types: hot-rolled H-beams and welded H-beams.
I-beam, also known as steel beam, is a long strip of steel with an I-shaped section. I-beams are divided into ordinary I-beams and light I-beams. I-beams are widely used in various building structures, bridges, vehicles, brackets, machinery, etc. The flanges of ordinary I-beams and light-duty I-beams gradually become thinner from the root to the edge, and have a certain angle. The models of ordinary I-beams and light-duty I-beams are expressed by Arabic numerals in centimeters of their waist heights.
Z-section steel is a common cold-formed thin-walled section steel, the thickness is generally between 1.6-3.0mm, and the section height is mostly between 120-350mm. The processing material is hot-rolled (painted), galvanized. Z-section steel is usually used in large-scale steel structure workshops. The processing length and holes are produced according to the processing requirements. Supporting products of Z-section steel: color steel tile; rock wool sandwich panel; floor deck, etc.
The types of C-shaped steel are: galvanized C-shaped steel, hot-dip galvanized C-shaped steel, inner beveled C-shaped steel, roof purlin C-shaped steel, C-shaped template support C-shaped steel for automobile profiles, precision C-shaped steel for equipment, etc. It is processed by cold bending of hot rolled plate, with thin wall and light weight, excellent section performance and high strength. Compared with traditional channel steel, the same strength can save 30% of materials. It is widely used in purlins and wall beams of steel structure buildings, and can also be combined 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.
