U 290x80x6.3
BR — Cold-formed Channel
Cold-formed channels (U shapes) are similar to C shapes but without stiffening lips. Used for light structural framing, supports, and secondary members.
The U 290x80x6.3 steel profile weighs 32.6 kg/m (21.93 lb/ft), has a depth of 290 mm (11.42 in), flange width 80 mm (3.15 in). Cross-sectional area: 2,715.9 mm². Moment of inertia Ix = 3,067.6 cm⁴, Iy = 125.61 cm⁴.
Cross-section (not to scale)
Gauge equivalent: 6.3 mm ≈ 3 gauge (Manufacturers Standard Gage)
