U 200x75x2.25
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 200x75x2.25 (UK / Australia)
The U 200x75x2.25 steel profile weighs 6.0 kg/m (4.05 lb/ft), has a depth of 200 mm (7.87 in), flange width 75 mm (2.95 in). Cross-sectional area: 772.3 mm². Moment of inertia Ix = 465.06 cm⁴, Iy = 39.41 cm⁴.
Cross-section (not to scale)
Gauge equivalent: 2.25 mm ≈ 13 gauge (Manufacturers Standard Gage)
