U 127x50x2.28 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 127x50x2.28 (UK / Australia)

The U 127x50x2.28 steel profile weighs 3.9 kg/m (2.64 lb/ft), has a depth of 127 mm (5.00 in), flange width 50 mm (1.97 in). Cross-sectional area: 500.46 mm². Moment of inertia Ix = 120.858 cm⁴, Iy = 11.814 cm⁴.
