In the 1930’s, times were difficult for the Norwegian engineering industry. Things improved when Norsk Hammerverk started importing steel. In addition, an outlet selling wallpaper and paints and colours was opened. Most of the shares had been bought by the company Gustav Aspelin, one of Norway’s leading suppliers of steel and construction materials. Gustav Aspelin later merged with Stormbull.
The company often moved locations. After the war, negotiations with local authorities in Stavanger led to the company taking over a seaside property in 1948, formerly used by Stavanger Støperi & Dok. This was the first time all the company’s activities were situated at the same location.
In 1967 a Swedish NOHA branch was established with the Hjalmarsson’s as co-owners. In 1974 the name was changed to NOHA Forsaljnings AB, and is today part of Kidde Sweden. The efforts in Sweden were successfull and it was suggested to make new models to meet market demands. It was decided that sales were to go through the HVAC-industry alone and still is today.
In 1973 an agreement was formed were Sandnes Aducerverk was to represent NOHA in Danmark. The company held a sales office outside Copenhagen and represented 7 Norwegian companies selling products to the HVAC-industry. Also Finland became a growing market, but competition from local manufacturers made it more difficult to settle there.
The production at Norsk Hammerverk increased, resulting in the facilities becoming too small and outdated. In 1987 it was decided to build a new factory at Forus. All activities the company was engaged in other than fire fighting equipment, were moved to separate companies. The administrative board approved the plans, and Norsk Hammerverk moved into a brand new factory early in 1988, a factory especially designed to manufacture fire hose reels and cabinets.
In 1999 Norsk Hammerverk sold to the global British company Williams plc (later merged and became Kidde plc). The corporation acquired several fire fighting companies and chose NOHA as center of excellence for fire hose reels. As a result of the merger and internationalization, NOHA Brannteknikk and Norsk Hammerverk merged and changed names to NOHA NORWAY AS from 1. January 2000.Kidde plc was in April 2005 acquired by the American corporation UTC – United Technologies Corporation.
In 2012 The Dutch SK FireSafety Group (SK) has acquired NOHA from UTC Climate, Controls & Security.
