Standard or custom weight

W-shape presets use the designation weight in lb/ft. Custom mode estimates two rectangular flanges plus the web using 490 lb/ft³.

Source and limitation

Standard shape data follows the AISC Shapes Database v16.0. Custom sharp-corner geometry omits root fillets and rolling tolerances.

No capacity calculation

The result is weight and optional cost only. It does not select a beam or verify span, bending, shear, deflection, stability, connections or loads.
