U 125x50x2.25 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 125x50x2.25 (UK / Australia)

The U 125x50x2.25 steel profile weighs 3.8 kg/m (2.58 lb/ft), has a depth of 125 mm (4.92 in), flange width 50 mm (1.97 in). Cross-sectional area: 489.597 mm². Moment of inertia Ix = 115.032 cm⁴, Iy = 11.616 cm⁴.
