C 250x50x20x6 Cintac · Weight & Dimensions

Cintac, cold-formed sections · 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 10 pulgadas (México) · PFC 250x50x20x6 (UK / Australia)

The C 250x50x20x6 steel profile weighs 16.5 kg/m (11.07 lb/ft), has a depth of 250 mm (9.84 in), flange width 50 mm (1.97 in). Cross-sectional area: 2,103.156 mm². Moment of inertia Ix = 1,634.063 cm⁴, Iy = 48.086 cm⁴.
