From the lead foundry to the distribution of plastic seals
Everything starts in 1929.
DEJOIE company based its production on lead, especially on lead seals. Second World War generated a shortage on raw material which compels the company to develop towards aluminium which supply remains steady. In 1952, DEJOIE won a supply bid for LA POSTE (ex PTT) and becomes the French manufacturer for aluminium mail boxes. At the same time, the company develops its activity on metallic and plastic seals through products adapted to the market, and becomes one of the main leaders on the sector.
