U 50x25x3.05
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 50x25x3.05 (UK / Australia)
The U 50x25x3.05 steel profile weighs 2.1 kg/m (1.42 lb/ft), has a depth of 50 mm (1.97 in), flange width 25 mm (0.98 in). Cross-sectional area: 277.1 mm². Moment of inertia Ix = 10.02 cm⁴, Iy = 1.38 cm⁴.
Cross-section (not to scale)
Gauge equivalent: 3.05 mm ≈ 11 gauge (Manufacturers Standard Gage)
