U 300 x 40,1 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 300 x 40,1 (UK / Australia)
The U 300 x 40,1 steel profile weighs 40.1 kg/m (26.95 lb/ft), has a depth of 300 mm (11.81 in), flange width 90 mm (3.54 in). Cross-sectional area: 5,108.124 mm². Moment of inertia Ix = 7,240.774 cm⁴, Iy = 404.423 cm⁴.
