Ramnäs has a fine history
Iron-manufacture in Ramnäs celebrated its four-hundredth anniversary in the year 1990. Ramnäs started as a Crown enterprise 1590 making wrought iron from pig iron. The first forging-hammer was built by assistants to the Queen dowager Catarina Stenbock, to whom the whole district belonged as fief.

Swedish wrought-iron played an important role in Swedish export the following three-hundred years. During the second half of the nineteenth century the wrought-iron manufacture in Ramnäs was completed with a rolling mill, thus creating a fully integrated manufacture of steel bars from pig iron. With good access to bar-material, chain production started 1876. Modern fabrication of anchor chain was initiated in Ramnäs 1943.

Ramnäs Bruk has through the years been a pioneer in the development of chain and connector design as well as in the introduction of new manufacturing, inspection and testing routines. New connector designs, Ramfor and Ramfor slim, were introduced in 1990 and a new stud chain design, with an asymmetric stud in combination with controlled stud expansion, was introduced in 1991.

The greatest step seriously affecting the development of anchor chain came during the 1960-th when the offshore industry started to utilise ships-chain for mooring of drill-ships and semi-submersible platforms. This kind of use diverged radically from the normal use of ships-chain. Offshore chain is continuously subject to load, whereas the chain on most ships is in rather infrequent use. Thus the offshore chain has to withstand considerably more severe conditions than ships-chain, particularly as regards resistance against fatigue.
