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 305x165x40 steel profile weighs 40.3 kg/m (27.08 lb/ft), has a depth of 303.4 mm (11.94 in), flange width 165 mm (6.50 in). Cross-sectional area: 5,064 mm². Moment of inertia Ix = 8,370.24 cm⁴, Iy = 764.17 cm⁴.
