U 125x50x3.04 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 125x50x3.04 (UK / Australia)

The U 125x50x3.04 steel profile weighs 5.1 kg/m (3.45 lb/ft), has a depth of 125 mm (4.92 in), flange width 50 mm (1.97 in). Cross-sectional area: 653.6 mm². Moment of inertia Ix = 151.044 cm⁴, Iy = 15.29 cm⁴.
