Efficient Cross - sectional Shape

The cross - sectional shape of H - steel is similar to the letter "H", consisting of two parallel flange plates and one web plate. This cross - sectional shape enables it to distribute stress more effectively when under load. For example, when subjected to vertical pressure, the flange plates mainly bear the bending stress, while the web plate mainly resists the shear stress, thus giving full play to the load - bearing capacity of the steel.

Excellent Axial Compressive Capacity

Due to its reasonable cross - sectional shape, H - steel has outstanding compressive performance in the axial direction (length direction). In building structures, such as the columns of high - rise buildings, H - steel can bear huge vertical loads and provide stable support for the building. Compared with steel of other shapes, H - steel with the same cross - sectional area can withstand greater axial pressure, which helps to reduce the amount of steel used and the self - weight of the structure.

Superior Bending Resistance

The flange plates of H - steel are relatively far from the neutral axis of the cross - section. According to the principles of mechanics of materials, when subjected to bending moment, it can generate a relatively large moment of resistance. This makes it perform outstandingly in beam structures. For instance, in the roof truss beams of industrial plants, the main girders of bridges and other structures, H - steel can effectively resist bending deformation and ensure the flatness and stability of the structure when under load.
