The size of HEB steel directly impacts its application. Smaller HEB sizes, such as HEB 100 - HEB 200, are often used for light - duty structures or in applications where space is limited, like in interior building frames or small - scale industrial facilities. Larger HEB sizes, such as HEB 600 - HEB 1000, are used for heavy - duty applications that require high load - bearing capacity. For example, in the construction of large - scale bridges or high - rise buildings, larger HEB steel beams can support the significant weight and lateral forces. The flange width and thickness also play a role; wider flanges provide better stability against lateral buckling, making them suitable for columns in tall structures
