S7X15.3 is an American Standard beam of 22.8 kg/m — AISC Shapes Database v15.0 publishes its section properties (A 2,903 mm², Ix 15,067,578 mm⁴) without the full profile dimensions, and the published values are tabulated below.
S-shapes are American Standard beams with narrow, tapered flanges — the oldest rolled I-profile in the catalogue, still used for crane rails and work on older structures.
This series publishes section properties without full profile dimensions, so the shape cannot be drawn to scale.
