U 50x25x3.04 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 50x25x3.04 (UK / Australia)

The U 50x25x3.04 steel profile weighs 2.1 kg/m (1.44 lb/ft), has a depth of 50 mm (1.97 in), flange width 25 mm (0.98 in). Cross-sectional area: 273.6 mm². Moment of inertia Ix = 9.805 cm⁴, Iy = 1.596 cm⁴.
