UPN 280
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 280 steel profile weighs 41.8 kg/m (28.09 lb/ft), has a depth of 280 mm (11.02 in), flange width 95 mm (3.74 in). Cross-sectional area: 4,400 mm². Moment of inertia Ix = 4,739.92 cm⁴, Iy = 293.03 cm⁴.
