Company RDT has manufactured hooks since 1997. Before that time the hooks were produced by company SMW- Stolberg's metal factory. Also hooks and eyes for the corsetry industry were made there.
In 1997 Mr. Dr. Engineer Michael Rittich established his company RDT - Dr. Ing. Michael Rittich Draht Technik - and bought this department from SMW. He reestablished the shrunken customer base, so that 2001 the enterprise could move to its own place of production in Alsdorf.
Due to the turbulences in the metal industry during the first decade of the 21st century the firm has specialised on the production of hooks in stainless steel, zinc coated steel and brass.
Hooks and eyes for the corsetry manufacture are only available, respectively produced on a small scale.
