Our H Beam Characteristics

H Beam has parallel or near-parallel flanges on the inner and outer sides, and the end of the flanges is at a right angle, so it is named parallel flange I-beam.The thickness of the web of

H Beam is smaller than that of the ordinary I-beam with the same height of the web, and the width of the flange is larger than that of the ordinary I-beam with the same height of the web, so it is also named wide flange I-beam. Determined by the shape, the section modulus, moment of inertia and corresponding strength of H Beam is significantly better than the same single-weight ordinary I-beam.

H-beam classification

There are many product specifications of H-beam, and the classification methods are as follows.

(1) According to the flange width of the product, it is divided into wide flange H-beam (HW), middle flange H-beam (HM) and narrow flange H-beam (HN). The flange width B of wide flange and middle flange H-section steel is greater than or equal to the web height H. The flange width B of the narrow flange H-beam is approximately equal to one-half of the web height H.

(2) According to product use, it is divided into H-shaped steel beam, H-shaped steel column, H-shaped steel pile, and extremely thick flange H-shaped steel beam. Sometimes parallel leg channels and parallel flange T-beams are also included in the scope of H-beams. Generally, the narrow flange H-beam is used as the beam material, and the wide-flange H-beam is used as the column material.

(3) According to the production method, it is divided into welded H-beam and rolled H-beam.

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