Heavy construction work with attention to detail
At Boonen NV in Dilsen-Stokkem, we combine years of expertise with high-quality craftsmanship for construction and welding work across a wide range of industries. Whether it involves manufacturing a robust steel structure, welding a stainless steel frame, or assembling complex machine parts: we deliver top-quality work that meets the highest standards.
We specialize in heavy-duty welding, assembling large and complex components into a single functional unit. This work often serves as a critical component of our turnkey projects in mechanical engineering and assembly.



Welding expertise in all metals
Thanks to our in-house quality control and the capability for NDT (non-destructive testing) weld inspections, all our welded structures meet the strictest safety requirements and industry standards. This makes us a reliable partner for both domestic and international projects.
Our welders are certified and familiar with various welding processes, including MIG/MAG, TIG, and shielded metal arc welding techniques. This allows us to work with a wide range of materials, such as:
1. Steel – for sturdy, load-bearing structures
2. Stainless steel – ideal for hygienic or corrosion-resistant applications
3. Duplex – for demanding environments with high chemical or thermal loads
4. Aluminium – lightweight yet strong, perfect for specific industrial applications
5. Copper and brass - wear-resistant and heat-resistant
6. Wear plates - designed for extreme wear conditions and require specific welding techniques and welding wire

OUR ADVANCED PREPARATION MACHINES FOR CONSTRUCTION WORK




For project preparation, we have an extensive machine park for cutting, bending, sawing, flame cutting, rolling, and finishing. This allows us to deliver every project seamlessly to our construction department.
We can handle both small parts and very large structures. Depending on the application, we bend and cut sheet material, saw profiles and solid pieces, and create complex shapes using CNC-controlled oxy-fuel, plasma, and laser cutting. For curved or cylindrical parts, we utilize our rolling mills.
The finishing takes place in a spacious spray booth with controlled drying conditions – think of workpieces the size of an entire truck. We always deliver custom solutions, regardless of size or complexity.


From design to finished welding project
The strength of Boonen NV lies in the comprehensive service we offer. We design, weld, machine, and assemble everyting entirely in-house. This ensures maximum control, a minimal margin for error, and smooth communication. Moreover, we tailor every project to your wishes, schedule, and functional requirements.
