C 120x50x15x1.6 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 5 pulgadas (México) · PFC 120x50x15x1.6 (UK / Australia)

The C 120x50x15x1.6 steel profile weighs 3.0 kg/m (2.02 lb/ft), has a depth of 120 mm (4.72 in), flange width 50 mm (1.97 in). Cross-sectional area: 383.158 mm². Moment of inertia Ix = 86.479 cm⁴, Iy = 13.215 cm⁴.
