In the 1970s, Golar Metall, based in the Norwegian town of Tvedestrand, developed a watertight door system.
IMS produced the steel for Golar Metall. In the 1980s, IMS bought the patent for the doors, and started manufacturing and supplying complete systems to customers throughout the world. In the late 1980s, IMS opened a production facility in the US.
In 1993, IMS further developed its door systems, becoming a specialist in low-threshold doors for all kinds of applications. This gave us a massive technological edge in the cruise market, where there is a great need to move things through doors.
IMS is now the world’s largest manufacturer of sliding, watertight door systems, making 1 100 doors a year.
