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 305x165x46 steel profile weighs 46.1 kg/m (30.98 lb/ft), has a depth of 306.6 mm (12.07 in), flange width 165.7 mm (6.52 in). Cross-sectional area: 5,806.6 mm². Moment of inertia Ix = 9,766.3 cm⁴, Iy = 895.45 cm⁴.
