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.
The C 140x60x25x4.75 steel profile weighs 10.4 kg/m (6.98 lb/ft), has a depth of 140 mm (5.51 in), flange width 60 mm (2.36 in). Cross-sectional area: 1,324.061 mm². Moment of inertia Ix = 379.588 cm⁴, Iy = 63.579 cm⁴.
