U 300x90x2.66
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 300x90x2.66 steel profile weighs 14.4 kg/m (9.68 lb/ft), has a depth of 300 mm (11.81 in), flange width 90 mm (3.54 in). Cross-sectional area: 1,255.6 mm². Moment of inertia Ix = 1,609.75 cm⁴, Iy = 85.4 cm⁴.
Cross-section (not to scale)
Gauge equivalent: 2.66 mm ≈ 12 gauge (Manufacturers Standard Gage)
