U 200x75x3.05
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.
Also known as: U 200x75x3.05 (UK / Australia)
The U 200x75x3.05 steel profile weighs 8.1 kg/m (5.44 lb/ft), has a depth of 200 mm (7.87 in), flange width 75 mm (2.95 in). Cross-sectional area: 1,039.6 mm². Moment of inertia Ix = 619.82 cm⁴, Iy = 51.8 cm⁴.
Cross-section (not to scale)
Gauge equivalent: 3.05 mm ≈ 11 gauge (Manufacturers Standard Gage)
