Wagener & Simon WASI

Wagener & Simon WASI (commonly known as WASI) is a German company specializing in stainless steel fasteners and connection elements. Founded in 1961 by Emil Wagener and Werner Simon in Wuppertal, the company has grown into a leading wholesale supplier of corrosion-resistant connection technology. Since 1978, WASI has been part of the Würth Group, a global market leader in assembly and fastening materials. The company is headquartered in Wuppertal-Ronsdorf and operates internationally with locations in Denmark, Spain, Belgium, and other countries. WASI offers a comprehensive range of over 21,000 products, including screws, nuts, washers, pins, securing elements, rivet and dowel technology, height adjustment elements, and custom special parts. The company serves both trade and industrial customers through two business units: WASI Handel (Trade) and WASI Industrie (Industry). Its products are made from stainless steels A1 to A5 and other special materials, conforming to DIN, EN, ISO, and WASI house standards. WASI also provides custom-designed and drawing-specific parts, often non-standardized, to meet individual customer requirements. In addition to its core fastener business, WASI has expanded into specialized segments such as Maritim (marine) in 1997 and SOLAR in 2007, offering mounting systems for photovoltaic roof constructions. The company emphasizes quality and service, maintaining an ISO 9001-certified management system and offering a mobile app for easy product access and ordering. With a team of 180 experts speaking 15 languages, WASI supports customers worldwide, ensuring reliable supply and logistics solutions. WASI's history reflects steady growth and internationalization. Starting as a local supplier, it established sales divisions and subsidiaries across Europe and beyond, including Spain (1998), Austria (2000), Denmark, Sweden, Croatia, and China (2002), Serbia (2003), Romania (2004), Bulgaria (2005), and Poland (2006). In 2017, the company consolidated its Wuppertal operations into a single site in Ronsdorf with an expanded logistics center and new administration building. Today, WASI continues to be a trusted partner for stainless steel connection technology, combining tradition with innovation.

Wagener & Simon WASI was founded in 1961 by Emil Wagener and Werner Simon in Wuppertal, Germany, as a company for stainless steel connection elements, initially marketing products under the names 'WASI A2' and 'WASI A4'. The location in Wuppertal proved optimal due to its proximity to the small ironware and metal processing industries and wire drawing mills, which were decisive during the founding era. In 1978, the company became part of the Würth Group, a global leader in fastening and assembly materials. In 1992, WASI established its Special Sales Division, focusing on mounting technology and height adjustment elements. The product range expanded in 1997 with the addition of the Maritim division, offering special stainless steel fasteners for water sports, boating, and shipping. International expansion began in 1998 with WASI Spain, followed by WASI Austria in 2000. In 2001, an automated high-bay warehouse was commissioned at the Wuppertal-Heckinghausen site. The following years saw the creation of new companies in Denmark, Sweden, Croatia, and China (2002), Serbia (2003), Romania (2004), Bulgaria (2005), and Poland (2006). In 2007, WASI added the SOLAR division, providing mounting solutions made of stainless steel and aluminum for photovoltaic roof constructions. Logistics were further expanded in 2009 with the opening of a second site in Wuppertal-Ronsdorf. In 2014, the business units WASI Industrie and WASI Handel were established to better serve industrial and trade customers. In 2017, the company was renamed WASI GmbH and consolidated its operations into a single location in Ronsdorf by expanding the logistics center and adding an administration building. This move also integrated direct connections to external locations in Spain, Denmark, and Belgium. Today, WASI continues to operate as a family-owned business within the Würth Group, employing around 180 experts. It maintains a comprehensive inventory of over 21,000 products and emphasizes quality, service, and sustainability. The company's history reflects a consistent strategy of growth, internationalization, and adaptation to market needs, solidifying its position as a leading supplier of stainless steel connection technology.
