Aluminium finishing in anodising baths has been one of GRONBACH’s core competences for decades. Our anodising plant in Wasserburg enables the anodising (anodisation) of surfaces and individual components made of aluminium for optical purposes without affecting the metallic character of the aluminium. Our anodising process leaves the existing structure of the metal or uses pre-treatment methods (brushing, grinding, blasting, polishing) and refines the surface in various colour designs and gloss spectra. Anodized surfaces are characterized above all by high scratch resistance, excellent protection against weather influences such as corrosion and dirt.
Anodic coating produces an extremely dense and hard oxide layer in an electrochemical process (electrolyte bath), which provides excellent protection against mechanical damage and weathering without impairing the metallic character of the aluminium. This anodised layer is firmly bonded to the aluminium, extremely hard, non-conductive and can be dyed abrasion-resistant using colour anodising. The anodized aluminum is finally compressed by boiling water.
For the various dyeing processes (including adsorptive, electrolytic or electrochemical polishing) a wide range of colours from natural aluminium to bronze to black is available in our plant in Wasserburg. Note: You can also request special colours from us at any time. The extremely scratch-resistant design surfaces can be processed and anodised by us up to a length of three metres.
GRONBACH – Your supplier for anodised surfaces and anodised coatings
As your anodising partner, we pre-treat a large number of manufacturing products individually according to customer requirements and appearance and design them with a wide variety of colour results. In addition to pre-treatment, we also produce various finishes using brushes, grinding, blasting and polishing.
Please feel free to contact us about your project. We will be happy to provide you with corresponding anodised samples.
Additional information on our anodizing processes, metal coatings and processing skills for metals such as stainless steel and aluminium can be found in our brochures, which you can order free of charge. In addition, our employees will be happy to answer any further questions you may have about our production technologies and our company network.
