C 325x75x21x3 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 13 pulgadas (México) · PFC 325x75x21x3 (UK / Australia)
