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 76.2x44.5x12.7x1.9 steel profile weighs 2.6 kg/m (1.78 lb/ft), has a depth of 76.2 mm (3.00 in), flange width 44.5 mm (1.75 in). Cross-sectional area: 336.756 mm². Moment of inertia Ix = 31.704 cm⁴, Iy = 9.107 cm⁴.
