UPN 80
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 80 steel profile weighs 8.6 kg/m (5.81 lb/ft), has a depth of 80 mm (3.15 in), flange width 45 mm (1.77 in). Cross-sectional area: 912 mm². Moment of inertia Ix = 84.47 cm⁴, Iy = 14.73 cm⁴.
