U 127x65x3 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 127x65x3 (UK / Australia)

The U 127x65x3 steel profile weighs 5.8 kg/m (3.91 lb/ft), has a depth of 127 mm (5.00 in), flange width 65 mm (2.56 in). Cross-sectional area: 741.394 mm². Moment of inertia Ix = 189.581 cm⁴, Iy = 31.471 cm⁴.
