U 200x50x3.42 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 200x50x3.42 (UK / Australia)

The U 200x50x3.42 steel profile weighs 7.8 kg/m (5.21 lb/ft), has a depth of 200 mm (7.87 in), flange width 50 mm (1.97 in). Cross-sectional area: 987.525 mm². Moment of inertia Ix = 520.813 cm⁴, Iy = 19.278 cm⁴.
