U 127x50x3.35
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 127x50x3.35 (UK / Australia)
The U 127x50x3.35 steel profile weighs 8.0 kg/m (5.37 lb/ft), has a depth of 127 mm (5.00 in), flange width 50 mm (1.97 in). Cross-sectional area: 726.8 mm². Moment of inertia Ix = 172.28 cm⁴, Iy = 15.4 cm⁴.
Cross-section (not to scale)
Gauge equivalent: 3.35 mm ≈ 10 gauge (Manufacturers Standard Gage)
