U 100 x 10,1 SAISC · Weight & Dimensions

SAISC, 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 100 x 10,1 (UK / Australia)

The U 100 x 10,1 steel profile weighs 10.1 kg/m (6.81 lb/ft), has a depth of 100 mm (3.94 in), flange width 50 mm (1.97 in). Cross-sectional area: 1,286.285 mm². Moment of inertia Ix = 205.479 cm⁴, Iy = 32.016 cm⁴.
