From tailored advice to the delivery of ready-to-build-in curved components, Kersten offers a complete solution.

Our team of professional staff works in clean, non-ferrous factories equipped with modern aluminium bending and processing machines. Quality is closely monitored throughout the entire process.


Machining operations

Kersten performs various machining operations, such as double mitre sawing, drilling, and milling of curved profiles.

We use modern 5-axis CNC machining centres which are specially designed for curved products.


Our team of experienced and certified welders carries out welding processes according to different industry standards:

  • TIG/GTAW (141)
  • MIG-MAG/GMAW-FCAW (131-135-136-138)


This is done according to the following qualifications:

  • CL1-certificate to DIN-EN 15085-2
  • DIN-EN 1090-3 EXC 1
  • EN-ISO 3834-2


Surface treatments

Depending on the application, the product is provided with technical or aesthetic surface treatments. Applying the correct coating can strongly improve material properties such as corrosion resistance, wear resistance, friction coefficient, and non-stick. For decorative properties, we offer the following processes, among others:

  • Anodising
  • Painting
  • Powder coating


Heat treatments

We carry out thermal treatments of aluminium products in our own ovens. These treatments include soft annealing and artificial aging (from T4 to T6).
