The main producer of manhole covers in Scandinavia is Ulefos Jernvaerk. It is also one of Europe's oldest businesses and is still a family concern. It was set up by royal decree of King Fredrick III on 8 August, 1657, which allowed the Cappelen family to begin operations. The family was involved in many different businesses over the years, including shipping, producing stoves, and casting manhole covers. Manhole covers now account for 70% of the family’s business.Now known as Ulefos NV AS, it produces gully tops and industrial castings in both Finland (Niemisen Valimo) and Norway (Ulefos Jernværk).
