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 150 (México) · Doble T ISMB 150 (Argentina / LATAM) · UB 150 (UK / Australia)
The ISMB 150 steel profile weighs 15.0 kg/m (10.08 lb/ft), has a depth of 150 mm (5.91 in), flange width 75 mm (2.95 in). Cross-sectional area: 1,870 mm². Moment of inertia Ix = 705.81 cm⁴, Iy = 56.39 cm⁴.
