Overview
NORMA Group SE, commonly styled as NORMA, is a German industrial manufacturer specializing in joining, connecting and fluid-management technologies. Its product portfolio includes hose clamps, couplings, quick connectors, pipe and hose connection systems, and related components used to secure, route or join flexible and rigid fluid lines. The company serves industrial applications in which controlled connections are important for safety, durability, leak prevention and efficient assembly. The company traces its origins to Rasmussen GmbH, established in 1949 by Ove Skafte Rasmussen, the son of Danish industrialist Jørgen Skafte Rasmussen. It remained family-owned for several decades. A major ownership and structural transition occurred in 2006, when a management buyout and a merger with ABA, a Swedish manufacturer, were financed by the private-equity firm 3i. The combined business adopted NORMA as its principal corporate and market identity. This transaction created the platform for a more international operating group built around complementary connection technologies and regional manufacturing capabilities. NORMA expanded through acquisitions during the following decade. In 2007 it acquired Breeze Industrial Products in the United States, adding another established name in clamping and connection products. In 2013 it purchased Craig Assembly, a Michigan-based specialist in injection-moulded components. In 2014 it acquired National Diversified Systems in California, whose activities included plastic water-piping products, and Chien Jin Plastic in Malaysia. These transactions broadened the group beyond metal clamps into plastic components, water-management products and application-specific assemblies. The company serves a range of end markets, including automotive, aviation, construction, shipping and industrial manufacturing. Its technologies are also used in cooling systems, emission-control applications, hose and water-pipe networks, and sterile pharmaceutical production. NORMA markets products under several names, including ABA, Breeze, Connectors, Serflex, Serratub, Terry, Torca and NORMA. The multi-brand portfolio reflects the group's history of acquisitions and its effort to retain established specialist brands in different markets and applications. NORMA became a publicly listed company in 2011 under its present name, which had already been used as a brand. Its shares trade on the Frankfurt Stock Exchange under the symbol NOEJ. The company was included in the SDAX by November 2015. Reference material reports approximately 8,900 employees in 2019 and production facilities including two plants in China and one in Brazil, alongside sites in other locations. Its business model combines engineered components, global manufacturing and distribution, and application-specific connection solutions for original-equipment manufacturers, industrial customers and other users of fluid-carrying systems.
History
NORMA Group began in 1949 as Rasmussen GmbH, founded by Ove Skafte Rasmussen. The founder was the son of Danish industrialist Jørgen Skafte Rasmussen, and the business remained under family ownership for much of its early history. Its industrial focus developed around components used to join, clamp and connect hoses, pipes and other fluid-carrying systems. The company's most important early transformation came in 2006. A management buyout, supported by 3i, was combined with a merger with ABA, a Swedish company operating in a related field. The transaction ended the company's longstanding family-owned structure and established a broader platform with multiple product technologies and market positions. NORMA, already used as a brand, became the name associated with the enlarged group. International expansion continued through a series of acquisitions. In 2007 the group acquired Breeze Industrial Products in the United States. In 2013 it bought Craig Assembly, a Michigan company specializing in injection-moulded components. In 2014 it acquired National Diversified Systems in California, which produced plastic water-piping products, and Chien Jin Plastic in Malaysia. These additions extended the business from traditional clamping and coupling products into moulded plastics and water-management applications, while also increasing its geographic reach. The group later operated across a range of industrial markets. Its components were used in automotive and aviation applications, construction and shipping, cooling and emissions systems, hose and water-pipe networks, and sterile pharmaceutical production. NORMA maintained a portfolio of established brands, including ABA, Breeze, Connectors, Serflex, Serratub, Terry, Torca and NORMA. This portfolio reflected both internal product development and the integration of acquired businesses. NORMA Group was listed on the Frankfurt Stock Exchange in 2011 under its current corporate name. By November 2015 it was included in the SDAX index of smaller German listed companies. Reference material identifies Maintal in Hesse, near Frankfurt, as the company's base. It also reports approximately 8,900 employees in 2019 and manufacturing operations that included two plants in China and one in Brazil, in addition to facilities elsewhere. The available reference material does not provide enough information to describe later ownership changes, current management, financial performance or the company's present operating footprint in detail.
