U 75x40x1.5
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 75x40x1.5 (UK / Australia)
The U 75x40x1.5 steel profile weighs 1.8 kg/m (1.18 lb/ft), has a depth of 75 mm (2.95 in), flange width 40 mm (1.57 in). Cross-sectional area: 225.8 mm². Moment of inertia Ix = 20.56 cm⁴, Iy = 3.52 cm⁴.
Cross-section (not to scale)
Gauge equivalent: 1.5 mm ≈ 16 gauge (Manufacturers Standard Gage)
