U 100 x 10,2 British Steel · Weight & Dimensions

British Steel, hot-rolled sections · 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 100 x 10,2 (UK / Australia)

The U 100 x 10,2 steel profile weighs 10.2 kg/m (6.86 lb/ft), has a depth of 100 mm (3.94 in), flange width 50 mm (1.97 in). Cross-sectional area: 1,299.765 mm². Moment of inertia Ix = 207.678 cm⁴, Iy = 32.302 cm⁴.
