U 100x50x2.66
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 100x50x2.66 (UK / Australia)
The U 100x50x2.66 steel profile weighs 4.0 kg/m (2.67 lb/ft), has a depth of 100 mm (3.94 in), flange width 50 mm (1.97 in). Cross-sectional area: 510.8 mm². Moment of inertia Ix = 80.12 cm⁴, Iy = 11.87 cm⁴.
Cross-section (not to scale)
Gauge equivalent: 2.66 mm ≈ 12 gauge (Manufacturers Standard Gage)
