U 200x75x6.3
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.
Also known as: U 200x75x6.3 (UK / Australia)
The U 200x75x6.3 steel profile weighs 16.1 kg/m (10.84 lb/ft), has a depth of 200 mm (7.87 in), flange width 75 mm (2.95 in). Cross-sectional area: 2,085.9 mm². Moment of inertia Ix = 1,193.78 cm⁴, Iy = 94.2 cm⁴.
Cross-section (not to scale)
Gauge equivalent: 6.3 mm ≈ 3 gauge (Manufacturers Standard Gage)
