H-shaped steel is an economical cross-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”.
The inner and outer sides of the flanges of H-shaped steel are parallel or close to parallel, and the flange ends are at right angles, hence the name parallel flange I-beam. The web thickness of H-shaped steel is smaller than that of ordinary I-beams with the same web height, and the flange width is larger than that of ordinary I-beams with the same web height, so it is also called wide-edge I-beam. Determined by its shape, the section modulus, moment of inertia and corresponding strength of H-shaped steel are significantly better than ordinary I-beams of the same unit weight. Used in metal structures with different requirements, it shows its superior performance whether it bears bending moment, pressure load, or eccentric load. It can greatly increase the load-bearing capacity compared with ordinary I-beams and save 10% to 40% of metal. H-shaped steel has wide flanges, thin webs, multiple specifications, and flexible use. It can save 15% to 20% of metal when used in various truss structures. Because the inner and outer sides of the flange are parallel and the edge ends are at right angles, it is easy to assemble and combine into various components, thus saving about 25% of the welding and riveting work, which can greatly speed up the construction speed of the project and shorten the construction period.
-Hot rolled H-beam production line process flow：
Steel plate – automatic striping – assembly – automatic submerged arc welding – flaw detection – flange correction – web correction – end face processing – sandblasting and rust removal – painting. The fully automatic submerged arc welding production line’s cutting, assembly and welding are all controlled by microcomputers to ensure that the dimensional accuracy of the H-shaped steel produced and the quality of the welds meet national standards. The steel structure building has a simple and lightweight structure, which expands the internal space of the building, saves steel, and has a short installation period. The roof and walls are made of colored profiled steel plates.
-Advantages of Hot Rolled H Beam
1.Steel structures based on hot-rolled H-shaped steel have a high degree of industrial manufacturing, are convenient for mechanical manufacturing, intensive production, high precision, easy installation, and easy to ensure quality.
2.The construction speed of the project is fast, the area is small, and it is suitable for all-weather construction and is less affected by climate conditions.
3.Increase the effective use area of the structure
4.Compared with welding H-shaped steel, it significantly saves labor and materials, reduces raw material, energy and labor consumption, has low residual stress, and has good appearance and surface quality.
5.Facilitates machining, structural connection and installation. Also easy to dismantle and reuse.
-Application Range
