Helical corrugated steel pipes are continuously formed circular tubes made by rolling galvanized steel strips into a specific wave pattern, bending them into a spiral shape, and allowing the edges to interlock. Invented in the United States in 1896, they have been in use for over a century and serve as an ideal substitute for concrete pipes and reinforced concrete structures.

Helical corrugated steel pipe features

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

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

Construction Fast: Pipe sections (adjustable from 1 to 12 meters), Clamp fast connection

Long lifespan: twice that of concrete pipes, up to 60-100 years

Helix-ribbed steel pipe applications

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

Passage Options: Highway-Rail Animal-Passenger Channels, Vehicle Passages, Small Open Tunnels, Sheltered Passages

Protection: Underground communication cables, gas pipeline protection tubes, urban common utility tunnels

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

Agriculture: farm well casing, canal irrigation, siphon pipe, grain storage facility
