C 250x75x21x2.5 Brausa · Weight & Dimensions

Brausa, 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 250x75x21x2.5 (UK / Australia)

The C 250x75x21x2.5 steel profile weighs 8.3 kg/m (5.60 lb/ft), has a depth of 250 mm (9.84 in), flange width 75 mm (2.95 in). Cross-sectional area: 1,063.881 mm². Moment of inertia Ix = 974.448 cm⁴, Iy = 74.609 cm⁴.
