U 100x50x2
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 (UK / Australia)
The U 100x50x2 steel profile weighs 3.0 kg/m (2.03 lb/ft), has a depth of 100 mm (3.94 in), flange width 50 mm (1.97 in). Cross-sectional area: 388 mm². Moment of inertia Ix = 61.79 cm⁴, Iy = 9.28 cm⁴.
Cross-section (not to scale)
Gauge equivalent: 2 mm ≈ 14 gauge (Manufacturers Standard Gage)
