BR — 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 200x60x20x2 steel profile weighs 7.8 kg/m (5.28 lb/ft), has a depth of 200 mm (7.87 in), flange width 60 mm (2.36 in). Cross-sectional area: 704 mm². Moment of inertia Ix = 417.87 cm⁴, Iy = 33.98 cm⁴.
