U 300x100x2.66
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.
Also known as: U 300x100x2.66 (UK / Australia)
The U 300x100x2.66 steel profile weighs 10.2 kg/m (6.87 lb/ft), has a depth of 300 mm (11.81 in), flange width 100 mm (3.94 in). Cross-sectional area: 1,308.8 mm². Moment of inertia Ix = 1,727.34 cm⁴, Iy = 115.07 cm⁴.
Cross-section (not to scale)
Gauge equivalent: 2.66 mm ≈ 12 gauge (Manufacturers Standard Gage)
