IMCA, 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 228.6x82.6x20.3x2.66 steel profile weighs 8.6 kg/m (5.80 lb/ft), has a depth of 228.6 mm (9.00 in), flange width 82.6 mm (3.25 in). Cross-sectional area: 1,099.166 mm². Moment of inertia Ix = 870.406 cm⁴, Iy = 93.774 cm⁴.
