UPN 50
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 50 steel profile weighs 5.6 kg/m (3.76 lb/ft), has a depth of 50 mm (1.97 in), flange width 38 mm (1.50 in). Cross-sectional area: 555 mm². Moment of inertia Ix = 20.57 cm⁴, Iy = 6.68 cm⁴.
