UB 127x76x13

EN — 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.

The UB 127x76x13 steel profile weighs 13.0 kg/m (8.74 lb/ft), has a depth of 127 mm (5.00 in), flange width 76 mm (2.99 in). Cross-sectional area: 1,602.4 mm². Moment of inertia Ix = 458.86 cm⁴, Iy = 55.66 cm⁴.
