Connections made of Steel.

WASI is more than just a screw dealer.


For more than 60 years, we have stood for high-quality stainless steel connections. From the very beginning, we have lived the service concept and have also been offering our customers individual special and drawing parts since 1961. The Wuppertal location has proven to be ideal for WASI right from the start: The proximity to the small iron and metal processing industry as well as to the wire drawing factories was decisive for the location in the early days. Today, WASI maintains excellent relations with leading stainless steel manufacturers all over the world.
