Your specialist for fall protection


Stahlbau W+Z Handelsges.mbH was founded on April 6, 1984 by Karl-Heinz Wagener, design engineer, and Reinhold Zander, master locksmith, as Stahlbau W+Z GmbH. The company was based in Gelsenkirchen. Our patent “Descent protection” was manufactured and distributed in our workshop in Gelsenkirchen. After Reinhold Zander left the company in 1993, it was renamed Stahlbau W+Z Handelsges.mbH. At the same time, the company headquarters were relocated from Gelsenkirchen to Wuppertal. Since 1984, our company has been selling the product “fall protection” with great success. Our customers include almost the entire chemical industry, suppliers to these as well as some car manufacturers. On April 6, 2004, the company celebrated its 20th anniversary. From 10.06.2011 the company operates under the name STAHLBAU W+Z Handelsges.mbH & Co.KG.
