U 50x25x2.5 IAS · Weight & Dimensions

IAS, cold-formed 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 50x25x2.5 (UK / Australia)

The U 50x25x2.5 steel profile weighs 1.8 kg/m (1.21 lb/ft), has a depth of 50 mm (1.97 in), flange width 25 mm (0.98 in). Cross-sectional area: 229.441 mm². Moment of inertia Ix = 8.458 cm⁴, Iy = 1.366 cm⁴.
