C 180x70x25x3.2 Acindar · Weight & Dimensions

Acindar, 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 7 pulgadas (México) · PFC 180x70x25x3.2 (UK / Australia)

The C 180x70x25x3.2 steel profile weighs 8.8 kg/m (5.89 lb/ft), has a depth of 180 mm (7.09 in), flange width 70 mm (2.76 in). Cross-sectional area: 1,116.631 mm². Moment of inertia Ix = 549.271 cm⁴, Iy = 75.401 cm⁴.
