U 300x100x2
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 (UK / Australia)
The U 300x100x2 steel profile weighs 7.7 kg/m (5.19 lb/ft), has a depth of 300 mm (11.81 in), flange width 100 mm (3.94 in). Cross-sectional area: 988 mm². Moment of inertia Ix = 1,311.35 cm⁴, Iy = 88.17 cm⁴.
Cross-section (not to scale)
Gauge equivalent: 2 mm ≈ 14 gauge (Manufacturers Standard Gage)
