Cintac, 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 250x100x20x6 steel profile weighs 21.2 kg/m (14.25 lb/ft), has a depth of 250 mm (9.84 in), flange width 100 mm (3.94 in). Cross-sectional area: 2,703.156 mm². Moment of inertia Ix = 2,527.283 cm⁴, Iy = 300.445 cm⁴.
