Brausa, 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 250x75x21x3 steel profile weighs 10.0 kg/m (6.71 lb/ft), has a depth of 250 mm (9.84 in), flange width 75 mm (2.95 in). Cross-sectional area: 1,266.789 mm². Moment of inertia Ix = 1,151.586 cm⁴, Iy = 86.954 cm⁴.
