Corrugated Steel Plates
HelCor® are helically corrugated steel pipes that are a popular solution for culverts and underground passages. They can be buried at the depth of over 30 meters and withstand rough conditions for decades. Comparing to its concrete alternatives, HelCor® is lighter, eco-friendlier and more economical.

In addition to the circular section, it is possible to produce the pipe-arch shape that decreases the pipe rise and increases the pipe span. For the same water level, the pipe-arch shape has 65-100% more water flow capacity than a round pipe with the same rise.
The steel of HelCor® structures is protected against corrosion by hot dip galvanizing. It ensures a lifespan of over 100 years. When properly implemented, these pipes do not need any special care. 99% of maintenance would consist of surface renovation 3-4 times a century.
Installation time of HelCor® is much shorter than for its concrete counterpart. The light pipes are assembled in sections with a team of one trained supervisor and regular workers. One crane or just an excavator and basic tools will be sufficient for successful installation. A culvert of 80×3 m can be assembled in just 1 day.
The installation is possible in various weather conditions, both cold and hot. The pipes will tolerate the range from -50°C to +50°C.
The high-strength steel, corrosion protection, and a simple structure all ensure the longevity of the HelCor® structures. The pipes could be designed either as continuously hot dip galvanized or with an additional 300 μm polymer film (TrenchcoatTM or W-ProtectTM) on one or both sides, in an environment with increased corrosive aggressiveness.
CO2 emissions, energy and water consumptions are significantly lower to produce steel as opposed to concrete. Steel is also environmentally friendly as it is 100% reusable. Finally, the quick installation of the pipes means minimal pollution of the area.
