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 4 pulgadas (México) · PFC 100x40x15x3.75 (UK / Australia)
The C 100x40x15x3.75 steel profile weighs 8.0 kg/m (5.34 lb/ft), has a depth of 100 mm (3.94 in), flange width 40 mm (1.57 in). Cross-sectional area: 731.3 mm². Moment of inertia Ix = 108.01 cm⁴, Iy = 15.03 cm⁴.
