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 203.2x76.2x20.3x2.66 steel profile weighs 7.8 kg/m (5.26 lb/ft), has a depth of 203.2 mm (8.00 in), flange width 76.2 mm (3.00 in). Cross-sectional area: 997.554 mm². Moment of inertia Ix = 626.868 cm⁴, Iy = 74.084 cm⁴.
