What is Advantages of ISWB OVER ISMB?

1. ISMB sections have relatively narrow and sloping flanges and a thick web compared to wide-flange sections (ISWB).

2. ISMB beam are not economical, which used for compression members,because of excessive material in the web and the lack of lateral stiffness due to the narrow flanges.

3. Wide-flange beams provides excellent sectional performance, with high bending and buckling resistance due to H-shaped arrangement of flanges and the web.

4. H-beam can be readily but welded,  and     a sound welding is assured.
