European standard H-beam specifications and standards

The European standard H-beam is an economical and efficient profile with a more optimized cross-sectional area distribution and a more reasonable strength to weight ratio. It is named after the same section as the English letter "H". Due to the fact that all parts of H-beam are arranged at right angles, H-beam has advantages such as strong bending resistance, simple construction, cost savings, and light structural weight in all directions, and has been widely used.

The European standard H-beam is a new type of economic building steel. H-shaped steel has an economical and reasonable cross-sectional shape, good mechanical properties, and uniform extension at various points on the section during rolling with low internal stress. Compared with ordinary I-shaped steel, it has the advantages of large cross-sectional modulus, light weight, and metal saving, which can reduce the weight of building structures by 30-40%; Due to the parallel inner and outer sides of its legs and the right angle of its legs, it can be assembled into components, saving up to 25% of the welding and riveting workload. Commonly used in large buildings that require high load-bearing capacity and good cross-sectional stability (such as factories, high-rise buildings, etc.), as well as bridges, ships, lifting and transportation machinery, equipment foundations, brackets, foundation piles, etc.

The inner and outer sides of the flange of H-beam (European standard) are parallel or nearly parallel, and the end of the flange is at right angles, hence the name parallel flange I-beam. The web thickness of H-beam is smaller than that of ordinary I-beam with the same height as the web, and the flange width is larger than that of ordinary I-beam with the same height as the web, hence it is also named wide flange I-beam. Determined by its shape, the cross-sectional modulus, moment of inertia, and corresponding strength of H-beams are significantly superior to ordinary I-beams of the same unit weight. When used in metal structures with different requirements, it exhibits superior performance in terms of bearing bending moment, pressure load, and eccentric load. It can greatly improve the bearing capacity compared to ordinary I-beams, saving 10% to 40% of the metal. The H-shaped steel has a wide flange, thin web, multiple specifications, and flexible use. When used in various truss structures, it can save 15% to 20% of metal. Due to the parallel inner and outer sides of its wing edges and the right angle of the edge ends, it is easy to assemble and assemble various components, which can save about 25% of the welding and riveting workload, greatly accelerate the construction speed of the project, and shorten the construction period.
