UPN 100
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 100 steel profile weighs 10.6 kg/m (7.12 lb/ft), has a depth of 100 mm (3.94 in), flange width 50 mm (1.97 in). Cross-sectional area: 1,092 mm². Moment of inertia Ix = 158.32 cm⁴, Iy = 21.89 cm⁴.
