U 140x50x3.05
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.
The U 140x50x3.05 steel profile weighs 7.9 kg/m (5.31 lb/ft), has a depth of 140 mm (5.51 in), flange width 50 mm (1.97 in). Cross-sectional area: 704.1 mm². Moment of inertia Ix = 199.59 cm⁴, Iy = 14.66 cm⁴.
Cross-section (not to scale)
Gauge equivalent: 3.05 mm ≈ 11 gauge (Manufacturers Standard Gage)
