U 20x25x2.0
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 20x25x2.0 steel profile weighs 1.0 kg/m (0.70 lb/ft), has a depth of 20 mm (0.79 in), flange width 25 mm (0.98 in). Cross-sectional area: 128 mm². Moment of inertia Ix = 0.85 cm⁴, Iy = 0.75 cm⁴.
