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 5 pulgadas (México) · PFC 127x50x17x1.5 (UK / Australia)
The C 127x50x17x1.5 steel profile weighs 4.0 kg/m (2.67 lb/ft), has a depth of 127 mm (5.00 in), flange width 50 mm (1.97 in). Cross-sectional area: 382.5 mm². Moment of inertia Ix = 96.66 cm⁴, Iy = 13.8 cm⁴.
