U 100x50x1.5
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 100x50x1.5 (UK / Australia)
The U 100x50x1.5 steel profile weighs 2.3 kg/m (1.54 lb/ft), has a depth of 100 mm (3.94 in), flange width 50 mm (1.97 in). Cross-sectional area: 293.3 mm². Moment of inertia Ix = 47.24 cm⁴, Iy = 7.17 cm⁴.
Cross-section (not to scale)
Gauge equivalent: 1.5 mm ≈ 16 gauge (Manufacturers Standard Gage)
