Steel has so many amazing properties that we do not hesitate to call it the building material of the future. And the present.

One of the great advantages of using steel in construction is that, compared to other building materials, you get a unique combination of high tensile strength and low weight. It is also much easier to transport steel than, for example, heavy concrete elements.

Steel is also a very flexible choice. This advantage offers great architectural freedom, making steel the preferred choice for many architects. A preference for steel is particularly evident when creative architects have to design distinctive company headquarters and other larger buildings with a bold edge and character.

In terms of economics, steel frequently offers the best business case. Both in the short and long term.

Finally, it should be noted that steel has very high recyclability. In fact, you could reasonably say that the steel in a building is just on loan. After it has served its purpose in the building, it can be returned as scrap and re-used in new applications. Given the continual advances in refinement methods, steel can even be upcycled and resurrected as a new and even better material.

CSK is one of Denmark’s leading suppliers of steel structures. We cover the entire value chain, and can therefore contribute knowhow and expertise at all phases, from design to final installation.

Functional beauty.
Step by step

Over the years, we have delivered many staircases that have provided architectural cohesion and served both a functional and sculptural role in the building.
Staircases offer countless design possibilities. The almost aristocratic signal value of a spiral staircase, the simple strength of the straight staircase and the elegance of an L or U-shaped staircase are all examples of how a staircase can transform a room and add value to it.

CSK has extensive experience with demanding staircases – both internal and external – and with their production, finishing and installation.

A staircase changes the room,
and offers both functional
and aesthetic value


With steel,
anything is possible

You do not have to limit yourself to straight lines and right angles when you build using steel. If you can imagine it and design it – you can also build it.

If you peruse our past projects, you will quickly see that CSK has supplied steel structures to some of the most spectacular building projects in the Nordic region. Many of these have had both an architectural and functional character that have placed huge demands on everything from planning and design to production, surface treatment, transportation, assembly and installation.

It is extremely rare that you will hear CSK say ‘no’. We might scratch our head and need time to think it over. But we always find a solution, and create even the most unusual buildings. Something unique.

  • Quotations with personal service

    Quotations with personal service

    All enquiries to CSK are dealt with in person by our professional sales department. To ensure a proper quotation, the materials and information received from the customer are carefully studied.

    Once a prospective customer has contacted the company and explained their requirements, we submit a non-binding quotation based on the specifications, the written material and the personal contact.

    The quotation will thus form the basis for future design and project clarification.

  • Specialist knowledge and collaboration

    Specialist knowledge and collaboration

    An important factor for any project – large or small – is that it must be the best solution for the customer while giving us the optimum opportunity to supply the best result. Therefore, it is to everyone’s benefit that we participate as early as possible in the projects, and contribute constructive options and solutions during the design process. Here we consider every conceivable and inconceivable challenge at every stage of the project. It is also here that the creative and innovative ideas are reviewed and assessed. We often use specialist consultants to solve special challenges. The design work takes place in close collaboration with the client, lead or main contractor as well as their consultants. Our design departments are staffed by experienced and creative engineers and developers who are always striving to find the optimum solution on behalf of our customers.

  • Highly qualified employees and advanced equipment

    Highly qualified employees and advanced equipment

    CSK is geared for the future in everything it does. Our drawing departments are manned by experienced and well-trained engineers and technical 3D drafters who master the latest 3D design tools. Consequently, we can quickly and efficiently produce drawings for any project. The main task of the drawing department is to transform the project presentation and design results into concrete working drawings which can be used to visualise the project. These drawings will also be used in production and later during installation.

    We use both Tekla and AutoCAD software. Our drawing tools also give the customer the opportunity to see the design in 3D. As a result, the customer is able to obtain a good impression of the finished steel solution at a very early stage. This in turn gives the customer the opportunity to correct and adjust any inexpediencies. Our skilled employees and 3D design tools ensure the highest degree of flexibility.

  • Stringent quality requirements and efficient logistics

    Stringent quality requirements and efficient logistics

    In production we operate with advanced CNC-controlled equipment, which is always being updated to the best and most efficient versions. Our rigorous quality assurance means that nothing is left to chance, and that we continuously run checks according to the highest standards. Our skilled and quality-conscious employees ensure that the quality of our steel structures is second to none.

    We also have a highly efficient logistics function which ensures that raw materials, quality requirements and efficient logistics ??? finished goods, construction site supplies etc. arrive at and leave the factory and construction sites in the most expedient way.
    Consequently, we can offer very precise planning, which ultimately leads to significant savings.
    The CSK factories in Thisted and Tukums have a wide range of modern and efficient machinery at their disposal, with everything from hand-held welding equipment and shot blasting and welding machines to CNC-controlled plasma cutters and CNC-controlled drilling/sawing machines.

    Final finish
    The last stage of the production process involves surface-treating the steel structures. This happens in our own paint shops according to customer specifications. Once the surface is dry, and the structure is ready for installation, it is loaded onto our trailers and driven to the construction site where our installation crew is ready.

  • We are experts – on land and sea and from the air

    We are experts – on land and sea and from the air

    Installation work requires considerable expertise, because often the crews are faced with tasks where no standard solutions exist. The actual installation work is the final stage of the process for any assignment undertaken by CSK. However, extensive planning and coordination work precedes the installation phase. This is because installing the individual elements requires that the right parts are on site at the right time – including cranes and trucks.

    The installation crew are experts who understand advanced welds and who are used to working in difficult conditions. Basically, installing steel structures requires well-trained and creative professionals. At CSK, safety is a key priority, and therefore all our installers complete a safety course. Our installers are equipped with everything they need to tackle the task in hand, and they are all very quality-conscious and capable of working independently. Finally, we do not leave the site before the task is finished – on time of course!

  • Overall evaluation and quality assurance

    Overall evaluation and quality assurance

    In addition to ongoing evaluation during the project phase, each project is concluded with an overall evaluation. Here, the project’s individual phases are reviewed from design to production and installation.

    Our evaluation of course also involves the customer’s experience and assessment. The evaluation is used to ensure that CSK meets both its customers’ and its own expectations at all times.
