U 75x40x1.9 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 75x40x1.9 (UK / Australia)

The U 75x40x1.9 steel profile weighs 2.2 kg/m (1.49 lb/ft), has a depth of 75 mm (2.95 in), flange width 40 mm (1.57 in). Cross-sectional area: 282.625 mm². Moment of inertia Ix = 25.375 cm⁴, Iy = 4.572 cm⁴.
