U 15x20x1.5
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 15x20x1.5 steel profile weighs 0.6 kg/m (0.41 lb/ft), has a depth of 15 mm (0.59 in), flange width 20 mm (0.79 in). Cross-sectional area: 75.8 mm². Moment of inertia Ix = 0.28 cm⁴, Iy = 0.29 cm⁴.
