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 275x80x25x4 steel profile weighs 14.3 kg/m (9.60 lb/ft), has a depth of 275 mm (10.83 in), flange width 80 mm (3.15 in). Cross-sectional area: 1,820.981 mm². Moment of inertia Ix = 1,960.536 cm⁴, Iy = 139.804 cm⁴.
