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: ISMB 175 (México) · Doble T ISMB 175 (Argentina / LATAM) · UB 175 (UK / Australia)
The ISMB 175 steel profile weighs 19.6 kg/m (13.17 lb/ft), has a depth of 175 mm (6.89 in), flange width 85 mm (3.35 in). Cross-sectional area: 2,440.6 mm². Moment of inertia Ix = 1,242.09 cm⁴, Iy = 92.37 cm⁴.
