C 275x80x25x3 NBE EA-95 · Weight & Dimensions

NBE EA-95, 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 11 pulgadas (México) · PFC 275x80x25x3 (UK / Australia)
