Flanged Nestable Corrugated Steel Pipe consists of half-round sections of corrugated steel pipe with external side flanges that are easily bolted together to form a circular corrugated steel pipe. It is developed in the early 1930’s to facilitate overseas shipping, sections can be nested into compact, easy-to-handle bundles allowing for economical transportation for long-haul distances, remote sites, or international destinations.

The steel corrugated sections are Galvanized (Z610) or , with corrugation profile of 68 x 13mm., The corrugated sheets are fabricated in standard lengths with an effective laying of 1088mm, with half-lengthed sections of 544 mm. The sheets are available in various thicknessess, including 1.6mm, 2.0mm, 2.5mm and 3.0mm to meet most structural design requirements.
