C 140x55x20x2 Dabarca · Weight & Dimensions

Dabarca, 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 5 ½ pulgadas (México) · PFC 140x55x20x2 (UK / Australia)
