U 200x75x3.35
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 200x75x3.35 (UK / Australia)
The U 200x75x3.35 steel profile weighs 8.9 kg/m (5.96 lb/ft), has a depth of 200 mm (7.87 in), flange width 75 mm (2.95 in). Cross-sectional area: 1,138.8 mm². Moment of inertia Ix = 676.45 cm⁴, Iy = 56.24 cm⁴.
Cross-section (not to scale)
Gauge equivalent: 3.35 mm ≈ 10 gauge (Manufacturers Standard Gage)
