Our story

We create future-proof steel structures
with a demonstrably low environmental impact

Circular construction requires more than simply applying sustainable materials. It demands an integrated approach in which detachability, reuse, material reduction, and CO2 impact are already considered at the design stage. Circulairstaal® brings these aspects together in one coherent steel solution. Through smart structural design choices and efficient use of materials, we deliver steel structures with a low MKI (0.055), a minimal CO2 footprint, and a high residual value.

ANIEK AVERESCH
 

We are Circulairstaal®. One of the most progressive steel construction companies in the Netherlands. We specialize in the design, fabrication, and assembly of circular steel structures with a low MKI and CO2 footprint. We support clients, architects, and developers in building demonstrably circular and Paris Proof projects, fully prepared for the requirements of 2030 and 2050—without compromising on quality, flexibility, or lifespan.

Market leader in circular, demountable, and Paris Proof steel structures

As specialists in circular steel construction, we make circularity tangible and demonstrable. Our steel structures are designed for multiple life cycles and are suitable for disassembly, reuse, and adaptation. Through efficient steel use and slender structural designs, we minimize environmental impact without compromising on quality, safety, or flexibility. In doing so, we help clients stay ahead of developments such as Paris Proof construction, stricter MPG requirements, and future reporting obligations.

Circulairstaal® focuses entirely on circular and sustainable steel solutions. We design steel structures that not only meet today’s sustainability ambitions but are also future-proof. We achieve this by applying circular steel with a low MKI and CO2 emissions, integrating demountable connections, and designing structures suitable for reuse. In addition, we support projects in delivering Paris Proof steel structures, actively contributing to climate targets.

Our approach starts at the design stage. Through modular dimensions and demountable detailing, we ensure that steel structures are easy to disassemble and adapt. In material selection, we focus on efficiency, minimal environmental impact, and maximum residual value. During production and assembly, we use prefabrication with connectors (dry connections), reducing waste. Finally, we make circularity transparent by substantiating (CO2) performance with MKI scores, LCA certificates, and BCI reports—fully aligned with current and future legislation.

In practice, circular steel construction demonstrates that sustainability and buildability go hand in hand. Our projects show that it is possible to realize steel structures with a lower environmental impact without compromising functionality or economic feasibility. By designing and building circularly, the result is not only a sustainable building, but also a structure with long-term value.

A steel structure by Circulairstaal® enables emission-free construction: during transport and assembly, we can choose to maximize the reduction of CO2 or nitrogen oxides (NOx). This makes the solution particularly suitable for nitrogen-sensitive projects and future-proof construction challenges.

Strong people. Strong constructions. At Circulairstaal® we see no boundaries, only opportunities. Our connectors make welding unnecessary. So, everyone can join in building! We believe in ownership, entrepreneurship, and enjoying work. Motivated people? That's who we build with.

Great question. At Circulairstaal®, everything we deliver is fully traceable, from origin to future destination. With recognised certifications, LCAs, and material passports, you can see in black and white the impact you avoid.

Because circular construction is the way to build future-proof, offering lower environmental impact, greater design freedom, and higher material value retention. Traditional building kicks problems down the road. With circular building you keep control over the value and flexibility of your project, and you can often benefit from subsidies and tax incentives. We can help with that.

Not if you approach it smartly. Our solutions meet the highest aesthetic and technical standards. Reused materials are finished so well they’re often indistinguishable from “new.” Thanks to lower waste costs, higher residual value, and flexible buildings, the total cost of ownership is often even lower.

All materials are rigorously inspected and certified wherever possible. You get the same warranties as with new materials. Plus, circular components are easy to replace or reuse, without demolition and without risks.

That’s exactly a major advantage of circular construction. Our steel structures are designed to be demountable and adaptable, so you can respond flexibly to future needs without major renovations.
