ISMB 500
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 500 (México) · Doble T ISMB 500 (Argentina / LATAM) · UB 500 (UK / Australia)
The ISMB 500 steel profile weighs 86.9 kg/m (58.40 lb/ft), has a depth of 500 mm (19.69 in), flange width 180 mm (7.09 in). Cross-sectional area: 10,941.1 mm². Moment of inertia Ix = 44,677.92 cm⁴, Iy = 1,675.96 cm⁴.
