Steel stacks – design, construction, and production – have been our in-house developed product since our founding in 1983, and we market and sell them throughout Europe. The stacks are manufactured in various sizes and configurations, with a maximum diameter of Ø6500 mm and heights of up to +130 meters.

VL Staal A/S serves as a sparring partner for customers in finding the optimal stack solution – from the initial steps in the design phase, through material selection and surface treatment, to transport, installation, and ongoing inspection and evaluation.

With our total concept – welding – machining – surface treatment – we act as a strategic subcontractor for one of the world’s leading machinery suppliers in separator technology. Each year, 400–500 machine frames are produced using advanced welding robot technology and large CNC-controlled machining centers.

Thanks to our well-developed welding expertise and our capacity to handle very large components, we are also a significant subcontractor of components for the wind turbine industry, tanks, and other steel structures.
