Dabarca, 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 140x55x20x1.5 steel profile weighs 3.3 kg/m (2.22 lb/ft), has a depth of 140 mm (5.51 in), flange width 55 mm (2.17 in). Cross-sectional area: 420.197 mm². Moment of inertia Ix = 128.077 cm⁴, Iy = 18.573 cm⁴.
