U 200x75x4.75
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 200x75x4.75 (UK / Australia)
The U 200x75x4.75 steel profile weighs 12.4 kg/m (8.32 lb/ft), has a depth of 200 mm (7.87 in), flange width 75 mm (2.95 in). Cross-sectional area: 1,594.8 mm². Moment of inertia Ix = 930.81 cm⁴, Iy = 75.5 cm⁴.
Cross-section (not to scale)
Gauge equivalent: 4.75 mm ≈ 7 gauge (Manufacturers Standard Gage)
