Make your own GEDACOLOR aluminum signs using anodized printing

The GEDACOLOR semi-finished products for the production of aluminum anodized signs, such as machine signs, nameplates or industrial signs, are known and popular worldwide due to their versatility and excellent price-performance ratio. The GEDACOLOR aluminum anodized signs are extremely durable and will therefore give you joy even after years, thanks to the high-quality anodized colors from GEDACOLOR.

The special thing about our system is that the anodizing process is interrupted so that our special colors can penetrate the aluminum pores that have not yet been compacted. You then simply continue anodising (compacting/sealing). This closes the pores and the color is now hermetically sealed in the aluminum oxide layer (anodized layer) and is therefore weather-resistant, solvent-resistant, scratch-resistant, graffiti-proof and temperature-resistant for years.

We offer our customers four options for producing anodized aluminum signs with GEDACOLOR products.

In addition to our standard sizes, we are also happy to produce individual cuts according to your specifications.

This system is particularly suitable for screen printing. Since the open-pored aluminum is sensitive to contamination and fingerprints, the GEDALU panels are equipped with a special protective coating. The material can only be printed with our GEDACOLOR screen printing inks (AS). The solvent-based paint passes through the protective layer so that it can penetrate the open anodized pores.
