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 325x75x21x4 steel profile weighs 15.6 kg/m (10.46 lb/ft), has a depth of 325 mm (12.80 in), flange width 75 mm (2.95 in). Cross-sectional area: 1,962.736 mm². Moment of inertia Ix = 2,805.207 cm⁴, Iy = 117.248 cm⁴.
