HelCor
Versatile solutions for culverts and underground passages
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 metres and withstand rough conditions for decades. Comparing to its concrete alternatives, HelCor® is lighter, eco-friendlier and more economical.
Hydraulic efficiency
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.
Long service life
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.
Fast and simple installation
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.
Suitable for extreme temperatures
The installation is possible in various weather conditions, both cold and hot. The pipes will tolerate the range from -50°C to +50°C.
Durability in aggressive environments
The high-strength steel, corrosion protection, and a simple construction, all ensure the longevity of the HelCor® pipes system.
Eco-friendly
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.
Applications:
- Roads and railway culverts
- Underground passages
