U 290x80x2.25
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 290x80x2.25 steel profile weighs 11.7 kg/m (7.83 lb/ft), has a depth of 290 mm (11.42 in), flange width 80 mm (3.15 in). Cross-sectional area: 997.3 mm². Moment of inertia Ix = 1,170.99 cm⁴, Iy = 51.98 cm⁴.
Cross-section (not to scale)
Gauge equivalent: 2.25 mm ≈ 13 gauge (Manufacturers Standard Gage)
