HelCor

Corrugated  Steel Plates 

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.

Features and Benefits

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.

    More information about corrugated steel pipes

    Corrugated steel pipes – Long-lasting and flexible design

    Corrugated steel pipes, such as HelCor®, provide a robust and adaptable solution for culverts, drainage systems, and underground passages. Engineered to endure harsh environments and extreme temperatures, these plates are ideal for road and railway culverts, ecological crossings, and hydrotechnical structures. Their flexibility simplifies installation, even in challenging conditions, while their long lifespan ensures minimal maintenance needs.

    Hydraulic efficiency and cost-effective performance

    Corrugated steel pipes are designed to optimize hydraulic flow, with pipe-arch shapes available to handle larger volumes of water compared to traditional round pipes. Hot-dip galvanizing provides corrosion protection, offering a lifespan exceeding 100 years, making them both economical and environmentally sustainable.

    Stainless steel pipes – Strength and corrosion resistance

    Stainless steel pipes are valued for their durability, corrosion resistance, and adaptability. Perfect for modern infrastructure, they excel in culverts, drainage systems, and underground passages requiring long-term performance. Their smooth interior enhances hydraulic flow, reducing blockages and improving water movement.

    Reliable and sustainable solutions

    Stainless steel pipes withstand extreme temperatures, chemical exposure, and demanding conditions. Suitable for road construction, ecological crossings, and industrial applications, they deliver strength, sustainability, and longevity, making them an excellent choice for modern infrastructure projects.
