The Djambi class was a class of steam corvettes of the Royal Netherlands Navy. The class comprised Djambi, Zoutman, Willem, Leeuwarden, Metalen Kruis and Curaçao. Later two ships of a supposedly 'slightly revised' type were built, the Zilveren Kruis-class corvettes.

Van Vlissingen en Dudok van Heel was a famous nineteenth-century Dutch machine factory. It built steam engines and machinery for the sugar industry and for maritime purposes, as well ships, rolling stock and large metal structures like the Moerdijk bridge and a floating dock. In 1871 it was reorganized to become the public company Koninklijke Fabriek van Stoom- en andere Werktuigen. In a second reorganization in 1890, parts of it were saved and continued under the name Koninklijke Nederlandsche Fabriek van Werktuigen en Spoorwegmaterieel, renamed to Werkspoor in 1927.
