U 127x50x2.66
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.
The U 127x50x2.66 steel profile weighs 6.3 kg/m (4.27 lb/ft), has a depth of 127 mm (5.00 in), flange width 50 mm (1.97 in). Cross-sectional area: 582.6 mm². Moment of inertia Ix = 139.97 cm⁴, Iy = 12.73 cm⁴.
Cross-section (not to scale)
Gauge equivalent: 2.66 mm ≈ 12 gauge (Manufacturers Standard Gage)
