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 80x40x15x2 steel profile weighs 2.8 kg/m (1.85 lb/ft), has a depth of 80 mm (3.15 in), flange width 40 mm (1.57 in). Cross-sectional area: 351.965 mm². Moment of inertia Ix = 34.974 cm⁴, Iy = 8.002 cm⁴.
