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 160x60x20x3 steel profile weighs 7.1 kg/m (4.75 lb/ft), has a depth of 160 mm (6.30 in), flange width 60 mm (2.36 in). Cross-sectional area: 900.789 mm². Moment of inertia Ix = 346.492 cm⁴, Iy = 42.904 cm⁴.
