Your partner for steel and metalworking
tradition, innovation and sustainability
Welcome to INTERSTAHL! For over 30 years, we have stood for innovative and sustainable partnerships with our customers and suppliers in the steel and metalworking sector.
Starting from our established steel service with sheets, coils and slit strip, our group of companies has successfully established itself in the field of mechanical processing and today serves an international customer base. We offer customised solutions, from coils, strips and sheets to precise plasma cuts and ready-to-install components, manufactured by milling, turning, drilling and grinding.
Our service philosophy combines in-house warehousing, flexible trading and efficient production. With generous storage capacities of over 6,000 square meters (heated halls and outdoor areas) and strategic forwarding warehouses, we guarantee comprehensive availability of our steel products.
Independence, innovation and customer proximity
INTERSTAHL Service GmbH & Co. KG and INTERSTAHL SÜD GmbH operate independently, but develop their product portfolios and services in close coordination in order to optimally utilise synergies and offer our customers added value. Our innovative strength is reflected in continuous investment in our machinery, hardware and software, as well as in the ongoing training of our team, so that we can always provide you with expert advice on all aspects of steel.
Use our contact form to enquire about your requirements or to get an overview of our wide range of steel products. Even if not everything is in stock, you can benefit from our excellent manufacturer contacts, which enable us to procure rare materials, material combinations and special dimensions.
Innovation Is Our Motor
Both companies are constantly working on finding further ways to create synergies in order to increase performance and attractiveness for our customers. In addition to a constant expansion of performance in the machine park and in hardware and software, continuous further training of our technical knowledge is a prerequisite. You will find competent contact persons in our staff for all aspects of steel. Every day they work to deliver innovative and sustainable products of the highest quality to our customers in various industries. Our interactive delivery programmme gives all interested visitors a good overview of our delivery possibilities. We do not have all of this in stock, but we do have the manufacturer contacts and can help with the procurement of rare materials, material combinations and dimensions.
Sustainability as an integral part of our corporate philosophy
The careful use of resources is a matter of course for us, both out of economic and ecological responsibility. We create healthy and attractive workplaces, because satisfied employees are the basis of our success. In our production, for example, we rely on state-of-the-art extraction technology with heat recovery for an optimal working environment. In addition, we actively support our customers in the marketing of surplus steel stock and thus make a contribution to sustainability.
