ISHB 350A
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 350A (México) · Doble T ISHB 350A (Argentina / LATAM) · UB 350 (UK / Australia)
The ISHB 350A steel profile weighs 72.4 kg/m (48.65 lb/ft), has a depth of 350 mm (13.78 in), flange width 250 mm (9.84 in). Cross-sectional area: 9,100.7 mm². Moment of inertia Ix = 19,548.67 cm⁴, Iy = 3,023.64 cm⁴.
