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 300x85x25x2 steel profile weighs 11.5 kg/m (7.75 lb/ft), has a depth of 300 mm (11.81 in), flange width 85 mm (3.35 in). Cross-sectional area: 1,024 mm². Moment of inertia Ix = 1,358.79 cm⁴, Iy = 96.22 cm⁴.
Cross-section (not to scale)
Gauge equivalent: 2 mm ≈ 14 gauge (Manufacturers Standard Gage)
