H-beam is a highly efficient economical profile (others are cold-formed thin-walled steel, profiled steel, etc.). Due to the reasonable cross-sectional shape, they enable steel to perform at a higher level and improve the ability to undertake cutting. Unlike ordinary I-beams, the flanges of H-beams are widened and the inner and outer surfaces are generally parallel, which facilitates the connection of high-strength snails to other components. Its size constitutes a reasonable series, the model is complete, easy to design and use.
In the structural design, the I-beam should be selected according to its mechanical properties, chemical properties, weldability and structural dimensions.
