UPN 120
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 UPN 120 steel profile weighs 13.4 kg/m (9.00 lb/ft), has a depth of 120 mm (4.72 in), flange width 55 mm (2.17 in). Cross-sectional area: 1,463 mm². Moment of inertia Ix = 298.96 cm⁴, Iy = 34.15 cm⁴.
