Whether for architecture, industry or metalworking, we enhance the finish of your components in the following colours:
(Our colour sample sheets based on EURAS colours are the basis for this):
C0 colourless | C2 light gold | C3 middle gold |
C4 dark gold | C31 light bronze | C32 bright bronze |
C33 middle bronze | C34 dark bronze | C35 black
We can also create intermediate colours on request.
Whether C2–C4 or C31–C35 AGRU always helps you to implement your special ideas and the architect's requests in an excellent way. Even in the 21st century, it is still not technically possible to reproduce an anodised hue with 100% accuracy in every batch. Thanks to our large load carrier inserts of up to 100 m² (depending on the geometry of the parts), we achieve outstanding colour uniformity despite this. Please note that threshold samples apply on an object-specific basis. These samples define the tolerances between maximum lightness and maximum darkness. As surface technology specialists, we always adhere to these limits.
Our employees at the anodising plant are highly trained and their eyes are trained to make demanding visual assessments. You can experience our top quality for yourself by checking out our references. Maybe we will soon be able to add your project to our reference list. We are happy to advise you personally and are always available to answer any questions you may have about colour and surface treatment for anodising.
Different pre-treatments, whether mechanical or chemical, allow us to finish the surface of the aluminium in various decorative or functional looks. We follow the specifications of ÖNORM C2531 and/or DIN 17611 here:
Without chemical or mechanical pre-treatment. Is used for technical applications to affect (or to only minimally affect) the dimensions of fittings and threads, for example. Sample inspection is essential for very high-precision parts, as there are only rough rules of thumb for this!
The parts are ground and anodised. The result is an attractive, metallic-looking surface with visible grinding strokes. If lightly dyed in bronze, this results in the well-known and popular “Stainless steel look”. Material defects are removed for the greater part.
The parts are brushed and anodised. This achieves a light glossy look with brush strokes. Here too, an attractive “Stainless steel look” can be achieved with a slight bronze tint. However, there are restrictions to the material defects which are removed.
The surface is polished and anodised. This results in a glossy finish. However, the material defects remain visible.
If there are defects in the material, such as scratches, scuff marks or corrosion, etc., a perfect finish can be achieved using this treatment by grinding first. The finish itself is identical to E2 Brushed. The surface is slightly glossy and with visible brush strokes.
Probably the most sophisticated and also the most expensive surface finish. The finish is glossy with brush marks visible in part. Material defects are removed for the greater part.
E1 - C3 light gold
E1 - C32 bright bronze
E4 stainless light silver
The most popular pre-treatment. Specific flattening additives in the alkaline pickling solution create a homogeneous, matt anodised surface which is typical and well-known. This is attractive and conceals minor material defects.
Strict monitoring and documentation of chemical parameters, skilled workers, highly trained laboratory technicians and independent, unannounced inspections by various institutions guarantee the highest quality and traceability for you. When anodising aluminium in various colours and surface finishes, we set great store by customer satisfaction and are your ideal partner for outstanding projects with strict requirements. If so desired, we are happy to accompany you on your journey to the perfect surface finish and to advise you on your technical options.
