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 250x50x20x5 steel profile weighs 14.1 kg/m (9.44 lb/ft), has a depth of 250 mm (9.84 in), flange width 50 mm (1.97 in). Cross-sectional area: 1,785.525 mm². Moment of inertia Ix = 1,416.278 cm⁴, Iy = 43.864 cm⁴.
