Q345B 200*150mm Stainless Steel H Beam Welded Galvanized For Construction

High Grade Q345B 200*150mm carbon steel welded galvanized Steel H Beam for construction

H-beam is an economical section and high-efficiency profile with more optimized cross-sectional area distribution and more reasonable strength-to-weight ratio. It is named because its cross section is the same as the English letter "H". Since all parts of the H-beam are arranged at right angles, the H-beam has the advantages of strong bending resistance, simple construction, cost saving and light weight in all directions, and has been widely used.

The inner and outer sides of the flange of H-beam are parallel or nearly parallel, and the flange ends are at right angles, so it is named parallel flange I-beam. The thickness of the web of the H-beam is smaller than that of the common I-beam with the same height of the web, and the flange width is larger than that of the common I-beam with the same height of the web, so it is also named wide-edge I-beam. Determined by the shape, the section modulus, moment of inertia and corresponding strength of H-beam are obviously better than ordinary I-beam of the same single weight. Used in metal structures with different requirements, whether it is subjected to bending moment, pressure load, or eccentric load, it shows its superior performance. Compared with ordinary I-beam, it can greatly improve the bearing capacity and save metal by 10% to 40%. H-beams have wide flanges, thin webs, many specifications, and flexible use. They can save 15% to 20% of metal when used in various truss structures. Because the inner and outer sides of the flanges are parallel, and the edge ends are at right angles, it is easy to assemble and combine into various components, which can save about 25% of the welding and riveting workload, which can greatly speed up the construction speed of the project and shorten the construction period.

Stainless steel H beam is a carbon structural steel for construction, which is a section steel with simple section, and is mainly used for metal components and frame of factory buildings. Good weldability, plastic deformation performance and certain mechanical strength are required in use. Stainless steel H beams have high strength and are flexible and rich in design. Compared with I-beams, they can save about 15% of metal under the same load-bearing conditions. There are many advantages in the use process, such as bending resistance, simple construction, cost saving and light structure weight.
1)Good corrosion resistance
2)High temperature oxidation resistance
3)Good physical property

Stainless steel H beam is widely used in construction, bridges, petrochemicals, marine engineering, Shipbuilding and other industries. L stands for low carbon, for example, 304L has lower carbon content than 304. H and s represent high temperature resistance. For example, 310S is more resistant to high temperature than 310. 304H is more heat resistant than 304. High temperature resistant stainless steel: 902.904.902L.904L, and its normal service temperature reaches 1800-2000 degrees. SS316 is a nuclear material. 316.316L is marine steel with strong corrosion resistance.

Use
Due to the above advantages, H-beams are widely used, mainly used for: various civil and industrial building structures; various large-span industrial plants and modern high-rise buildings, especially industrial plants in areas with frequent seismic activity and high temperature working conditions; requirements Large-scale bridges with large bearing capacity, good section stability and large span; heavy equipment; highways; ship skeletons; mine support; foundation treatment and dam engineering; various machine components.
