Advantages and application range of H-shaped steel

 The inner and outer sides of the H-shaped steel flange are parallel or nearly parallel, and the flange ends are 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 increase the construction speed of the project, and shorten the construction period.

H-shaped steel is widely used, mainly for various civil and industrial building structures; Various large-span industrial factories and modern high-rise buildings, especially in areas with frequent seismic activity and under high-temperature working conditions; Large bridges with high load-bearing capacity, good cross-sectional stability, and large spans are required; Heavy equipment; Expressway; Ship skeleton; Mine support; Foundation treatment and embankment engineering; Various machine components.

There are many product specifications for H-shaped steel, and there are several classification methods. (1) According to the flange width of the product, it is divided into wide flange, medium flange, and narrow flange H-shaped steel. The flange width B of H-shaped steel with wide and medium flanges is greater than or equal to the web height H. The flange width B of narrow flange H-shaped steel is approximately half of the web height H. (2) According to product usage, it is divided into H-shaped steel beams, H-shaped steel columns, H-shaped steel piles, and * thick flange H-shaped steel beams. Sometimes parallel leg channel steel and parallel flange T-shaped steel are also included in the scope of H-shaped steel. Generally, narrow flange H-shaped steel is used as the beam material, and wide flange H-shaped steel is used as the column material. Therefore, it is also known as beam H-shaped steel and column H-shaped steel. (3) According to production methods, it is divided into welded H-beams and rolled H-beams.

The inner and outer sides of the H-shaped steel flange are parallel or nearly parallel, and the flange ends are 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.
