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 150x65x20x2 steel profile weighs 4.8 kg/m (3.22 lb/ft), has a depth of 150 mm (5.91 in), flange width 65 mm (2.56 in). Cross-sectional area: 613.684 mm². Moment of inertia Ix = 218.155 cm⁴, Iy = 36.377 cm⁴.
