SAISC, 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 300x100x20x2.5 steel profile weighs 10.2 kg/m (6.86 lb/ft), has a depth of 300 mm (11.81 in), flange width 100 mm (3.94 in). Cross-sectional area: 1,308.881 mm². Moment of inertia Ix = 1,773.673 cm⁴, Iy = 157.056 cm⁴.
