ISJB 175 — Dimensions & Section Properties
IS — Wide Flange (I-beam)
Wide flange beams (W shapes / I-beams) are the most common structural steel profile used in building construction. They are used for beams, columns, and girders in steel-framed buildings and bridges. Designed per AISC 360, Eurocode 3, and NBR 8800.
Also known as: ISJB 175 (México) · Doble T ISJB 175 (Argentina / LATAM) · UB 175 (UK / Australia)
The ISJB 175 steel profile weighs 8.1 kg/m (5.44 lb/ft), has a depth of 175 mm (6.89 in), flange width 50 mm (1.97 in). Cross-sectional area: 1,009.3 mm². Moment of inertia Ix = 468.37 cm⁴, Iy = 10.05 cm⁴.
