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 225 (México) · Doble T ISMB 225 (Argentina / LATAM) · UB 225 (UK / Australia)
The ISMB 225 steel profile weighs 31.1 kg/m (20.90 lb/ft), has a depth of 225 mm (8.86 in), flange width 110 mm (4.33 in). Cross-sectional area: 3,905.1 mm². Moment of inertia Ix = 3,395.49 cm⁴, Iy = 262.22 cm⁴.
