How about Q355B high frequency welding H-beam

Structural weight is light. Compared with the concrete structure, the weight of the structure is light, the reduction of the weight of the structure, reduce the internal force of the structure design, can make the building structure foundation processing requirements are low, the construction is simple, the cost is reduced. Increase the effective use area of the structure. Compared with concrete structure, steel structure column section area is small, which can increase the effective use area of the building, depending on the different forms of the building, can increase the effective use area of 4-6%.

High structural stability. The hot rolled H-beam is the main steel structure, its structure is scientific and reasonable, good plasticity and flexibility, high structural stability, suitable for bearing vibration and impact load of large building structure, strong ability to resist natural disasters, especially suitable for some building structures in earthquake zones. According to statistics, in the last 7.0 magnitude of the devastating earthquake disaster, the H-shaped steel mainly steel structure of the damage degree is small.

The inner and outer flanges of H-beams are parallel or nearly parallel, and the ends of the flanges are at right angles, hence the name parallel flanged I-beams. The thickness of the web of H-beam is smaller than that of ordinary I-beams with the same height of the web, and the width of the flange is larger than that of ordinary I-beams with the same height of the web, so it is also named wide rim I-beams. Determined by the shape, the section modulus, moment of inertia and corresponding strength of H-beam are obviously better than that of ordinary I-beam with the same single weight. Used in different requirements of the metal structure, whether under bending moment, pressure load, eccentric load show its superior performance, can greatly improve the bearing capacity than ordinary I-steel, metal saving 10% ~ 40%. H beam has wide flange, thin web, many specifications and flexible use, which can save 15% ~ 20% metal in various truss structures.

Because the flange is parallel inside and outside, the edge end is at a right Angle, easy to assemble and assemble into various components, which can save about 25% of the welding and riveting work, can greatly speed up the construction of the project, shorten the construction period. The section shape is similar to the capital Latin letter H of an economic section profile, also known as steel beam, wide edge (edge) I beam or parallel flange I beam. The cross section of H-beam usually includes two parts: web and flange plate, also known as waist and side. H-beam steel is an economical and efficient profile with more optimized section area distribution and more reasonable strength-to-weight ratio, so it is named because its section is the same as the English letter "H".

The section shape of H beam is economical and reasonable, and the mechanical properties are good. When rolling, each point on the section extends more 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 reduce the building structure by 30-40%. And because its legs are parallel inside and outside, the leg end is a right Angle, assembly and combination into components, can save, riveting work up to 25%. It is often used in large buildings (such as factories, high-rise buildings, etc.) that require large bearing capacity and good cross-section stability, as well as Bridges, ships, hoisting machinery, equipment foundation, bracket, foundation pile, etc. Hot rolled H-beam can be divided into wide flange H-beam, middle flange H-beam and narrow flange H-beam. The main materials are Q235B, SM490, SS400, Q235B, Q345, Q345B, etc. They are mainly used in beam and column members of industrial and civil building steel structures, steel piles and supporting structures of underground engineering, and large-span steel bridge members. Ship, machinery manufacturing frame structure, train, automobile girder bracket, etc.

Compared with ordinary I-beam, H beam has the advantages of large section modulus, light weight and metal saving. H beam is an economical section steel, widely used in industry, construction, Bridges, oil drilling platforms and so on. Compared with ordinary I-beam, H-beam has large section modulus and can save 10-15% of metal under the same bearing conditions.
