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.
Also known as: Montén de 8 pulgadas (México) · PFC 200x75x20x4.75 (UK / Australia)
The C 200x75x20x4.75 steel profile weighs 19.2 kg/m (12.90 lb/ft), has a depth of 200 mm (7.87 in), flange width 75 mm (2.95 in). Cross-sectional area: 1,762.3 mm². Moment of inertia Ix = 1,063.31 cm⁴, Iy = 122.3 cm⁴.
