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 400x75x15x4 steel profile weighs 17.4 kg/m (11.66 lb/ft), has a depth of 400 mm (15.75 in), flange width 75 mm (2.95 in). Cross-sectional area: 2,214.736 mm². Moment of inertia Ix = 4,514.967 cm⁴, Iy = 106.679 cm⁴.
