Two locations, one strong surface expertise
Rieger Metallveredlung GmbH & Co KG has stood for high-quality galvanic surface solutions and reliable industrial processes for more than 70 years. With the RIXAL® brand, the company is bundling its expertise in the field of aluminium finishing and thus strengthening its position as a specialized partner for demanding applications.
The range of services extends from functional coatings for the electrical industry to decorative and highly corrosion-resistant surfaces for a wide variety of industrial applications.
Steinheim am Albuch – Technology meets versatility
The main site in Steinheim am Albuch is the technological center of the company. Here, Rieger offers an exceptionally broad portfolio of surface technology processes – far beyond classic electroplating processes.
The offer includes, among other things:
- Tin plating for electrical applications
- Electrolytic and chemical nickel plating
- Anodizing aluminium
- Decorative chrome plating on a trivalent basis
- Silver plating for optimum electrical conductivity
- Copper plating
- Passivation and pre-anodization
- Electroless nickel (NiP systems) for complex geometries
- Special aluminum coatings such as NICAL, RICAL, RICHEMAL, GALVANOX, CHEMALOX and DUOXAL
The process portfolio is supplemented by extensive mechanical pre- and post-processing such as grinding, polishing, sandblasting as well as cleaning and degreasing processes. This enables Rieger to offer complete process chains from a single source – from pre-treatment to the finished functional surface.
Technologically, the company combines highly automated systems with manual flexibility. Fully automated anodizing lines with integrated testing enable efficient series production, while manual electroplating offers individual solutions for complex components.
A particular focus is on the finishing of aluminum. Above all in the area of anodizing and galvanic coatings on aluminium, expertise is being systematically developed under the RIXAL® brand.
Mühlhausen location – growth and scalability
With the Mühlhausen site, Rieger is expanding its capacities in a targeted manner and creating the basis for further growth.
The focus is on:
- the expansion of series capacities
- Increasing delivery capability and deadline reliability
- the establishment of strategic redundancies for critical processes
The close cooperation between the two sites creates an integrated production system that combines high flexibility with industrial scalability. Customers benefit from stable processes, high supply security and reliable delivery performance.
Holistic surface solutions
The particular strength of Rieger Metallveredlung lies in the combination of:
- a broad process portfolio
- Comprehensive aluminum expertise
- integrated process chains
- two efficient locations
The result is not just individual coatings, but technically coordinated and integrated surface solutions for a wide range of requirements.
