C 220x80x25x2.5 IAS · Weight & Dimensions

IAS, cold-formed sections · Cold-formed Lipped Channel

Cold-formed lipped channels (C shapes) are lightweight profiles commonly used as purlins, girts, and light framing members. The stiffening lips increase local buckling resistance. Designed per AISI S100 and NBR 14762.

Also known as: Montén de 9 pulgadas (México) · PFC 220x80x25x2.5 (UK / Australia)

The C 220x80x25x2.5 steel profile weighs 8.1 kg/m (5.46 lb/ft), has a depth of 220 mm (8.66 in), flange width 80 mm (3.15 in). Cross-sectional area: 1,033.881 mm². Moment of inertia Ix = 765.376 cm⁴, Iy = 90.176 cm⁴.
