UPN 65 — Dimensions & Section Properties
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.
Also known as: PFC 65 (UK / Australia)
The UPN 65 steel profile weighs 7.1 kg/m (4.76 lb/ft), has a depth of 65 mm (2.56 in), flange width 42 mm (1.65 in). Cross-sectional area: 728.8 mm². Moment of inertia Ix = 45.29 cm⁴, Iy = 10.54 cm⁴.
