U 100x50x6.3 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 100x50x6.3 (UK / Australia)

The U 100x50x6.3 steel profile weighs 8.9 kg/m (5.96 lb/ft), has a depth of 100 mm (3.94 in), flange width 50 mm (1.97 in). Cross-sectional area: 1,129.44 mm². Moment of inertia Ix = 160.952 cm⁴, Iy = 26.243 cm⁴.
