DIECKMANN

Erich Dieckmann GmbH (EDI) is a German manufacturer with more than 85 years of experience in the development and production of high-quality door and window hardware. The company’s roots date back to around 1870, while the EDI brand itself was established in 1938 in Iserlohn, Germany — a region historically recognized as one of Europe’s leading centers for metalworking and architectural hardware manufacturing.

EDI specializes in the production of aluminium and stainless steel door handles, window handles, and security hardware for residential, public, and commercial buildings, including standard, profile-frame, emergency exit, and fire-rated doors. The company’s product portfolio combines German engineering precision, long-lasting durability, and contemporary design, delivering solutions that meet modern architectural, safety, and functional requirements.

All product development and the majority of manufacturing are still carried out at the company’s facility in Iserlohn, maintaining strict “Made in Germany” quality standards and ensuring full control over every stage of production. Erich Dieckmann GmbH is a trusted partner for architects, door manufacturers, interior designers, and construction professionals worldwide, offering functional, sustainable, and secure hardware solutions for contemporary building projects.
