Who we are

We are a world market leader operating on integrated global markets. When it comes to customer services for our three business units, Building Technology, Casting Technology and Rolled Products, the company headquarters and central production site in Olpe is supported by six German and nine foreign sales offices. As well as Germany, our sites are located in the Netherlands, Switzerland, Austria, Czech Republic, Denmark, the United Kingdom, the United States, China and Singapore.

Our core business is enhanced by our affiliated subsidiaries. In the Rolled Products business unit, this is Profiltech Stufenbandprofile GmbH in Keltern, which manufactures high-precision profiled strip. The design competency in Building Technology is complemented by Dendrit Haustechnik-Software GmbH in Dülmen.

Kemper cast products - non-machined and machined

Casting Technology - gunmetal parts - non-machined and machined

Our products place us among the world's leading suppliers. A major contributor to this is our vast experience in casting copper alloys. We are a specialist when it comes to particularly demanding and durable products. Expertise and experience are the basis of our exceptional quality. At the same time, we are our own single biggest customer because the renowned KEMPER branded valves for drinking water installations are produced at the foundry. The gunmetal used is not only corrosion-resistant, it also meets the strict requirements of the German Drinking Water Regulation - and is even lead-free, now and in the future.

Rolled Products - copper and copper alloy strips

Our rolled products place us amongst the world leaders in the production of copper and alloy strips for the automotive and electronics industries. The high quality of our strips, which only a few companies worldwide are able to produce to this standard, is crucial when it comes to miniaturising electronic components.

The growing pace of electrification, networking, smart technology and sensor technology will also ensure continued progress in this area for the future. And we offer the right solutions for all these sectors thanks to our classic bronze and high-performance alloys. The company’s subsidiary, Profiltech Stufenbandprofile GmbH, finishes rolled strips by profiling them to customer specifications.
