The history of DEJONG goes back to 1859. In that year the copper smith was established that forms the foundation of the current company. DEJONG supplied pots, pans and jugs for farmers in the Gorredijk region. After the rise of the dairy and cheese factories at the end of the nineteenth century, DEJONG developed into the leading supplier of milk churns in the Netherlands.

The decreasing demand for those churns after 1960 was compensated with an increasing demand for beer vessels and soft drink containers. Those were supplied all over Europe. Already since 1934 DEJONG has been processing stainless steel, initially for the dairy industry. This material turned out to be an excellent alternative for tinned steel and aluminum. Since 1970 DEJONG has also been manufacturing hot water tanks in stainless steel. These hot water tanks are now the main product.
