UPN 320
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 320 steel profile weighs 59.5 kg/m (39.98 lb/ft), has a depth of 320 mm (12.60 in), flange width 100 mm (3.94 in). Cross-sectional area: 6,692 mm². Moment of inertia Ix = 8,983.63 cm⁴, Iy = 440.44 cm⁴.
