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 300x80x25x4 steel profile weighs 15.1 kg/m (10.13 lb/ft), has a depth of 300 mm (11.81 in), flange width 80 mm (3.15 in). Cross-sectional area: 1,917.543 mm². Moment of inertia Ix = 2,409.484 cm⁴, Iy = 142.618 cm⁴.
