Helical corrugated steel pipes are continuously circular tube-shaped bodies formed by rolling galvanized steel strips into a certain wave pattern, bending them into a circular shape, and then spiraling them so that the edges interlock. Invented in the United States in 1896, they have been in use for over a century and are an ideal substitute for concrete pipes and reinforced concrete structures.

Helical corrugated steel pipe features

High compressive strength: 1.5 to 5 times that of the same diameter cement pipe.

Lightweight and easy to transport: 1/5 to 1/10 the weight of the same diameter concrete pipe

Construction Fast: Pipe sections (adjustable from 1~12 meters), clamp fast connection

Long service life: twice as long as concrete pipes, up to 60-100 years

Helical ribbed steel pipe applications

Drainage: Domestic water discharge, industrial wastewater discharge, road culvert drainage

Passageways: Highway-rail animal and human passageways, vehicle passageways, small open tunnels, sheltered passageways

Protection: Underground communication cables, pipeline protection for gas networks, urban common ducts

Industrial: Coal mine ventilation pipes, coal mine shafts, pile foundation shells, industrial chimneys

Agriculture: Field well casing pipes, canal irrigation, siphon pipes, grain storage facilities
