U 50x25x1.9 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 50x25x1.9 (UK / Australia)

The U 50x25x1.9 steel profile weighs 1.4 kg/m (0.94 lb/ft), has a depth of 50 mm (1.97 in), flange width 25 mm (0.98 in). Cross-sectional area: 178.125 mm². Moment of inertia Ix = 6.771 cm⁴, Iy = 1.084 cm⁴.
