U 25x30x2.0
EN — 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.
The U 25x30x2.0 steel profile weighs 1.3 kg/m (0.85 lb/ft), has a depth of 25 mm (0.98 in), flange width 30 mm (1.18 in). Cross-sectional area: 158 mm². Moment of inertia Ix = 1.69 cm⁴, Iy = 1.37 cm⁴.
