U 125 x 14,8 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 125 x 14,8 (UK / Australia)

The U 125 x 14,8 steel profile weighs 14.8 kg/m (9.92 lb/ft), has a depth of 125 mm (4.92 in), flange width 65 mm (2.56 in). Cross-sectional area: 1,879.805 mm². Moment of inertia Ix = 483.078 cm⁴, Iy = 80.018 cm⁴.
