H-beam Specification Diagram

There are four forms of h-beam specifications.

1. According to the width of the product flange, it is divided into wide flange, middle flange and narrow flange H-beam. The flange width b of the wide flange and middle flange H-section steel is greater than or equal to the web height H, and the flange width b of the narrow flange H-section steel is about half of the web height H.

2. According to the use of the product, it can be divided into H-shaped steel beam, H-shaped steel column, H-shaped steel pile, H-shaped steel flange extra-thick beam. Sometimes parallel leg channels and parallel flange T-beams are also included in the scope of H-beams. Beam materials generally use narrow flange H-beams, and column materials generally use wide-flange H-beams.

3. According to the production method, it can be divided into welded H-beam and rolled H-beam.

4. According to the specifications and sizes, it is divided into large, medium and small H-beams. Generally speaking, products with web height h above 700mm are called large size, 300-700mm are medium size, and products with web height less than 300mm are called small size. By the end of 1990, the world's largest H-beam had a web height of 1200 mm and a flange width of 530 mm.

Use of H-beam

H-beams are widely used and are 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; large bearing capacity and cross-section are required. Large bridges with good stability and large span; heavy equipment; highways; ship skeletons; mine support; foundation treatment and embankment engineering; various machine components.
