NBE EA-95, 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 140x50x20x2 steel profile weighs 4.2 kg/m (2.81 lb/ft), has a depth of 140 mm (5.51 in), flange width 50 mm (1.97 in). Cross-sectional area: 531.965 mm². Moment of inertia Ix = 156.527 cm⁴, Iy = 18.915 cm⁴.
