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 305x165x54 steel profile weighs 54.0 kg/m (36.29 lb/ft), has a depth of 310.4 mm (12.22 in), flange width 166.9 mm (6.57 in). Cross-sectional area: 6,808.8 mm². Moment of inertia Ix = 11,563.54 cm⁴, Iy = 1,062.71 cm⁴.
