Pipe-arch is a modification of round pipe in its low-profile. It is especially designed for culverts, bridges and underpasses with limited headroom, providing hydraulic benefits at low flow velocity. Usually, pipe-arches are equipped with end treatments to improve performances.
Culvert end treatment in steel is light and versatile Pipe-arch fabricated by structural plates are used in arctic weather, for its performance will not be severely affected
Benefits:
Lightweight: Steel or aluminum arches are so light to easy installation, for their mass approximately 1/10 and 1/30 respectively the mass of concrete structures.
Strength: Corrugations and soil arching around the pipe-arch make this lightweight structure to withstand relatively high loads, such as the impact and vibration of trucks, cars, trains and other vehicles and equipment.
Durability: Galvanized or aluminized coating significantly extends the life span reducing percentage of repairmen or maintenance.
Aesthetic appearance: Shining pipe-arch profile adds an attractive view to entry statements or embankment.
Applications:
Pipe-arches are often applied as culverts, small bridges, fish passages, grade separations.
