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 2 pulgadas (México) · PFC 50x25x10x3.05 (UK / Australia)
The C 50x25x10x3.05 steel profile weighs 2.4 kg/m (1.61 lb/ft), has a depth of 50 mm (1.97 in), flange width 25 mm (0.98 in). Cross-sectional area: 328.8 mm². Moment of inertia Ix = 11.96 cm⁴, Iy = 2.59 cm⁴.
