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

Helical corrugated steel pipe features

High compressive strength: 1.5~5 times that of the same diameter concrete 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 as long as cement pipes, up to 60-100 years

Helicoidal corrugated steel pipe applications

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

Passageways: Highway and railway animal crossings, vehicle passages, small cut-and-cover tunnels, and sheltered passages

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

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

Agriculture: Field well casing, irrigation channels, siphon pipes, grain storage silos
