U 127x50x4.76 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 127x50x4.76 (UK / Australia)

The U 127x50x4.76 steel profile weighs 7.9 kg/m (5.31 lb/ft), has a depth of 127 mm (5.00 in), flange width 50 mm (1.97 in). Cross-sectional area: 1,005.988 mm². Moment of inertia Ix = 230.55 cm⁴, Iy = 22.716 cm⁴.
