Value chain
Value chain
Through our deep value chain, we manufacture a wide variety of aluminum products for you. Whether individual components, small welded assemblies, aggregates up to large modules, we develop the best solutions in close cooperation with our customers. Our highly automated production line with in-line measurements guarantees the highest component quality.
Complex further processing
Whether components or assemblies – we refine your profile into ready-to-install components. With precise high-performance saws, state-of-the-art CNC machining centers and welding cells, we cover all the work steps right up to the finished surface. With our facilities for further processing in Austria and Slovakia, and in close cooperation with renowned partners, we can provide you with an economical and efficient offer.
Integrated processing
Sawing, milling, punching, embossing, drilling, turning, bending, welding, surface treatment (anodizing, powder coating, pickling passivation, KTL), engraving, setting fasteners, brush burrs, barrel finishing, and more...
Profiles
The profile is the basic product of our direct extrusion plant in Marktl, Austria. We offer a very wide range of high-precision cross-sections with tight tolerances as well as multifunctional profiles, special applications with special material properties (e.g. bendable, crimpable) and functional applications (e.g. cooling fins for heat dissipation in lighting fixtures).
For our customers in the automotive sector, we offer a wide range of OEM-approved materials:

Products in record time
Products in record time
We manufacture approx. 33,000 tons of aluminum profiles per year with our direct extrusion presses, maintain long-standing customer relationships, and distinguish ourselves by our fast and flexible way of acting. From inquiry to tooling technology and metallurgical testing to the finished product, we manage the product introduction process in record time!
The direct extrusion process
1. Heating
The material is heated to approx. 450 °C (approx. 840 °F).
2. Pressing
With a force of approximately 2,500 t, the aluminum is pressed through the extrusion die.
3. Cooling and cutting to length
The profile is cooled and cut to the desired length after forming saw packs.
4. Heat treatment and testing
In the final step, the material is brought to the desired strength by appropriate heat treatment. If necessary, a laboratory test follows.

Highest quality standards
Simulation of heat treatment processes
By simulating heat treatment processes, we check their effects on the material properties and microstructure of our products.
CNC machines
Testing machines and specimen preparation on modern CNC machines enable us to determine many technologically relevant mechanical characteristic values.
Metallography
Preparation of samples with state-of-the-art equipment for visualization of the microstructure and its characterization, damage analysis by fracture pattern analysis, scanning electron microscopy.
Corrosion tests
These are carried out according to automotive standards.
Spark spectroscopy
Checking and ensuring the chemical composition of the aluminum alloys used.
Locations and Certificates
At our production sites in Austria (Marktl) and Slovakia (Žarnovica), we collaborate with customers to develop solutions that optimally meet their requirements both technologically and economically. We have the expertise, experience, capacity and technical equipment to produce precisely machined and finished aluminum profiles in the desired time and quantity. We are certified according to the following standards: ISO 9001, ISO 14001, ISO 45001, IATF 16949, AEO, EN 15088.
