C 140x50x20x1.5 Mundi · Weight & Dimensions

Mundi, 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 ½ pulgadas (México) · PFC 140x50x20x1.5 (UK / Australia)

The C 140x50x20x1.5 steel profile weighs 3.1 kg/m (2.09 lb/ft), has a depth of 140 mm (5.51 in), flange width 50 mm (1.97 in). Cross-sectional area: 396.171 mm². Moment of inertia Ix = 116.391 cm⁴, Iy = 14.192 cm⁴.
