U 75x40x2.28 Tecnometal · Weight & Dimensions

Tecnometal, cold-formed sections (Brazil) · 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 75x40x2.28 (UK / Australia)

The U 75x40x2.28 steel profile weighs 2.6 kg/m (1.77 lb/ft), has a depth of 75 mm (2.95 in), flange width 40 mm (1.57 in). Cross-sectional area: 336.3 mm². Moment of inertia Ix = 29.827 cm⁴, Iy = 5.394 cm⁴.

Cross-section (not to scale)

Gauge equivalent: 2.28 mm ≈ 13 gauge (Manufacturers Standard Gage)
