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 120x50x20x3 steel profile weighs 5.7 kg/m (3.80 lb/ft), has a depth of 120 mm (4.72 in), flange width 50 mm (1.97 in). Cross-sectional area: 720.789 mm². Moment of inertia Ix = 155.661 cm⁴, Iy = 24.962 cm⁴.
