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 180x60x20x2 steel profile weighs 5.1 kg/m (3.44 lb/ft), has a depth of 180 mm (7.09 in), flange width 60 mm (2.36 in). Cross-sectional area: 651.965 mm². Moment of inertia Ix = 316.375 cm⁴, Iy = 31.683 cm⁴.
