Helical corrugated steel pipes are continuously circular tube-shaped bodies formed by rolling galvanized steel strips into a specific wave pattern, bending them into a spiral shape, and causing 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 to 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 concrete pipe

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

Helical corrugated steel pipe applications

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

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

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

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

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