U 230 x 25,1 KS · Weight & Dimensions

KS, 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 230 x 25,1 (UK / Australia)

The U 230 x 25,1 steel profile weighs 25.1 kg/m (16.88 lb/ft), has a depth of 230 mm (9.06 in), flange width 75 mm (2.95 in). Cross-sectional area: 3,200.805 mm². Moment of inertia Ix = 2,676.487 cm⁴, Iy = 176.088 cm⁴.
