Helical corrugated steel pipes are continuously circular tubes formed 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 are an ideal substitute for concrete pipes and reinforced concrete structures.

Helical corrugated steel pipe features

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

Lightweight and easy to transport: 1/5 to 1/10 the weight of standard concrete pipes

Construction Fast: Pipe sections (adjustable from 1~12 meters), quick clamp connections

Helical corrugated steel pipe applications

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

Passageways: Road and rail crossings for people and livestock, vehicle passages, small cut-and-cover tunnels, and sheltered passages

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

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

Agricultural supplies: field well casing pipes, canal irrigation, siphon pipes, grain storage silos
