Deep corrugation makes it possible for ultra-heavy loading

Superior corrugation with 381mm pitch and 140mm depthSuper annular corrugation plate pipes and arches produce far heavier loads than conventional corrugated structural plate because it deeper corrugation - 381mm pitch by 140mm depth. Deep corrugation aids in withstanding the heaviest loading and expanding service period. Apart from deep corrugation profile, flange connection is another innovation. It effectively combines easy installation and reduce cost and time.

CMP pipes and arches with super corrugation are internationally accepted and widely used for their versatility and economical purposes. They are extensively used as bridges, road or rail underpasses, stream crossings, box culverts and reclaim tunnels and other similar applications.
