U 90x30x2.66
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 90x30x2.66 steel profile weighs 4.4 kg/m (2.95 lb/ft), has a depth of 90 mm (3.54 in), flange width 30 mm (1.18 in). Cross-sectional area: 377.8 mm². Moment of inertia Ix = 42.52 cm⁴, Iy = 2.59 cm⁴.
Cross-section (not to scale)
Gauge equivalent: 2.66 mm ≈ 12 gauge (Manufacturers Standard Gage)
