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 200x80x25x2.5 steel profile weighs 7.7 kg/m (5.19 lb/ft), has a depth of 200 mm (7.87 in), flange width 80 mm (3.15 in). Cross-sectional area: 983.881 mm². Moment of inertia Ix = 612.652 cm⁴, Iy = 87.437 cm⁴.
