U 50x25x2.25
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.
Also known as: U 50x25x2.25 (UK / Australia)
The U 50x25x2.25 steel profile weighs 1.6 kg/m (1.09 lb/ft), has a depth of 50 mm (1.97 in), flange width 25 mm (0.98 in). Cross-sectional area: 209.8 mm². Moment of inertia Ix = 7.88 cm⁴, Iy = 1.12 cm⁴.
Cross-section (not to scale)
Gauge equivalent: 2.25 mm ≈ 13 gauge (Manufacturers Standard Gage)
