The Company

A Modern Steel Service with Tradition

Welcome to our website! For more than 30 years we have been standing for innovative and sustainable cooperation with our customers and suppliers. In addition to the original products of steel service, cut to size, sheet metal, coil and slit strip, a company has been established which in the meantime has opened up a further international customers in the field of mechanical processing. From plasma-fired blanks to milling, turning, drilling and grinding, we supply ready-to-install parts. From the very beginning our service philosophy has been characterized by a combination of our own warehousing, trade and production. Approximately 3,000 square meters of heated halls and an outdoor area that is almost twice as large, as well as various forwarding warehouses enable us to provide generous production and storage facilities.

We Are Independent and Autonomous

Both INTERSTAHL Service GmbH & Co KG and INTERSTAHL SÜD GmbH are independent companies, but develop their product portfolios and services in close coordination. For example, we give our customers financial flexibility by storing for them and delivering on demand.

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.


Careful use of resources is a matter of course for us. This idea has not only a financial background but also a health aspect. Healthy, attractive jobs and satisfied employees are a basic requirement for a successful company. In our production area, for example, we have an extraction system with heat recovery linked to every machine, for an optimal workplace climate. For us, sustainability also means supporting our customers in the marketing of excess stock. You will find a competent partner in us!

INTERSTAHL Service GmbH was founded on 02.01.1990 by its present managing director Thomas Grosch. In the meantime we can look back on 30 years of successful development. The support of our customers has always been and remains our main focus. Today the markets are changing rapidly. This continuous challenge is a constant incentive to find adequate solutions for constantly new requirements. A prerequisite for being a competent partner in all steel-related issues is also the continuous upgrading of our technical expertise, which we take very seriously. Throughout all changes, cooperation with our partners that is characterized by fairness, trust and humanity is an important goal for us. We know what we can do and we do it!
