In-house surface treatment

To ensure a high-quality surface treatment of our products, our plant contains our own anodizing and powder coating facilities.

In addition to our own products, we also offer surface treatment services to our customers as well.

This enables us to offer our customers a wide variety of colour and surface options on our windows:


Aluminium parts are anodized in sulphuric acid electrolyte.

Anodized coatings are available in natural, black, or on request in bronze colour.

Powder coating

Powder coating is the most up to date environmentally friendly surface treatment for corrosion protection.

It is suitable for all metal surfaces, making it the most sought-after coating.

Powder coating is available in RAL 9011, RAL 7021, RAL 9005, and RAL 9017.

We are Qualicoat Seaside certified since 2019.
