U 100x50x4.76 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 100x50x4.76 (UK / Australia)

The U 100x50x4.76 steel profile weighs 6.9 kg/m (4.63 lb/ft), has a depth of 100 mm (3.94 in), flange width 50 mm (1.97 in). Cross-sectional area: 877.468 mm². Moment of inertia Ix = 130.196 cm⁴, Iy = 20.985 cm⁴.
