U 380 x 53,9 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 380 x 53,9 (UK / Australia)

The U 380 x 53,9 steel profile weighs 53.9 kg/m (36.24 lb/ft), has a depth of 380 mm (14.96 in), flange width 100 mm (3.94 in). Cross-sectional area: 6,874.071 mm². Moment of inertia Ix = 15,034.23 cm⁴, Iy = 642.987 cm⁴.
