About Klaus Flender e.K.
Klaus Flender e.K. is a third-generation family business based in Schwelm, specialising in custom-made products in apparatus and vessel construction as well as metal and sheet metal work. The product range includes industrially required apparatus, vessels and made-to-measure items made of stainless steel, aluminium and St-grade steels, as well as railing and balcony installations for private customers. Since the 1970s, a key focus has been the processing of acid- and heat-resistant stainless steel. Manufacturing includes welding (manual metal arc, TIG, MIG, MAG, oxy-acetylene, spot welding), cutting, bending, rolling, sawing and profile rolling; a core business area is sheet metal and pipe processing in the 0.5 to 10 mm range. Customers include the automotive industry, paper industry, sewage treatment plant construction and the chemical industry.
