U 300x90x6.3
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 300x90x6.3 steel profile weighs 34.1 kg/m (22.93 lb/ft), has a depth of 300 mm (11.81 in), flange width 90 mm (3.54 in). Cross-sectional area: 2,904.9 mm². Moment of inertia Ix = 3,604.69 cm⁴, Iy = 179.83 cm⁴.
Cross-section (not to scale)
Gauge equivalent: 6.3 mm ≈ 3 gauge (Manufacturers Standard Gage)
