UPN 300
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 300 steel profile weighs 46.2 kg/m (31.05 lb/ft), has a depth of 300 mm (11.81 in), flange width 100 mm (3.94 in). Cross-sectional area: 4,700 mm². Moment of inertia Ix = 5,818.42 cm⁴, Iy = 348.82 cm⁴.
