U 300x90x3.05
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 300x90x3.05 steel profile weighs 16.5 kg/m (11.10 lb/ft), has a depth of 300 mm (11.81 in), flange width 90 mm (3.54 in). Cross-sectional area: 1,436.1 mm². Moment of inertia Ix = 1,834.82 cm⁴, Iy = 96.71 cm⁴.
Cross-section (not to scale)
Gauge equivalent: 3.05 mm ≈ 11 gauge (Manufacturers Standard Gage)
