ISHB 450
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: ISHB 450 (México) · Doble T ISHB 450 (Argentina / LATAM) · UB 450 (UK / Australia)
The ISHB 450 steel profile weighs 87.2 kg/m (58.60 lb/ft), has a depth of 450 mm (17.72 in), flange width 250 mm (9.84 in). Cross-sectional area: 10,991.5 mm². Moment of inertia Ix = 38,773.05 cm⁴, Iy = 3,571.02 cm⁴.
