UPN 180
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 180 steel profile weighs 22.0 kg/m (14.78 lb/ft), has a depth of 180 mm (7.09 in), flange width 70 mm (2.76 in). Cross-sectional area: 2,368 mm². Moment of inertia Ix = 1,073.44 cm⁴, Iy = 87.91 cm⁴.
