H-beam steel size and advantages

2021-01-04 14:12:29

H-beam steel is a kind of high-efficiency and economical cross-section profile. Its cross-sectional shape is designed reasonably, which can make the steel better perform its functions and have high-strength load-bearing capacity. This kind of steel is different from ordinary I-shaped steel.

The flange of the H-beam steel adopts a widening design, and its inner and outer surfaces are usually parallel, which facilitates the connection between high-strength bolts and other connecting members. The size of the H-beam forms a reasonable system, and the types are abundant, which is convenient for design and selection.

The thickness of the flanges of the H-beam steel is the same, and it has a rolled cross-section and a combined cross-section welded by three plates. However, I-beams are all rolled sections, and the production process is relatively poor, with a 1:10 slope on the inner edge of the flange.

In the rolling process of H-beam steel, it is different from ordinary I-beams. Ordinary I-beams only use a set of horizontal pressure rollers, while the flanges of H-beam steel are relatively wide and have no slope, which requires an additional set of vertical The pressing rollers roll at the same time, therefore, the performance of H-beam steel is better than that of I-section steel.
