UPN 350
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 350 steel profile weighs 60.6 kg/m (40.72 lb/ft), has a depth of 350 mm (13.78 in), flange width 100 mm (3.94 in). Cross-sectional area: 7,112 mm². Moment of inertia Ix = 11,225.8 cm⁴, Iy = 450.59 cm⁴.
