U 50x25x2.66
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.
Also known as: U 50x25x2.66 (UK / Australia)
The U 50x25x2.66 steel profile weighs 1.9 kg/m (1.26 lb/ft), has a depth of 50 mm (1.97 in), flange width 25 mm (0.98 in). Cross-sectional area: 244.8 mm². Moment of inertia Ix = 9.02 cm⁴, Iy = 1.26 cm⁴.
Cross-section (not to scale)
Gauge equivalent: 2.66 mm ≈ 12 gauge (Manufacturers Standard Gage)
