U 180 x 26,1 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 180 x 26,1 (UK / Australia)

The U 180 x 26,1 steel profile weighs 26.1 kg/m (17.51 lb/ft), has a depth of 180 mm (7.09 in), flange width 90 mm (3.54 in). Cross-sectional area: 3,319.305 mm². Moment of inertia Ix = 1,817.433 cm⁴, Iy = 276.742 cm⁴.
