In 1929, Karl Martinson bought a mobile sawmill which his son, Sigurd Martinson, then travelled with around the countryside surrounding Bygdsiljum.

In 1941, Sigurd Martinson built a permanent sawmill in Bygdsiljum on the same site on which the factory stands today.

In 1954, a limited company was established in which all of the Martinson children became part-owners. Sales at that time were approximately SEK 500,000.

In 1963, Sigurd's sons Nils and Åke Martinson took over control of the business.

1965 marked the beginning of glulam production.

1970 saw the establishment of the first specialised glulam factory.

In 1975, a sawmill was erected at Bygdsiljum, which at the time was Europe's most modern, being computerised and using advanced electronics.

1984 saw the fourth generation of Martinsons take over management of the company. Production of Martinsons' unique Comwood poles - developed in-house - also began in the same year.

In 1986, the second glulam factory was established in Bygdsiljum. Production here is mainly intended for the German market. Comwood poles are also manufactured here.

In 1989, Martinsons built its first wooden bridge at Klintforsån in Skellefteå.

In 1992, Martinsons began sales of glulam to Japan. These sales have since grown so as to make Japan the company's largest export market for glulam.

Hällnäs Såg AB was incorporated into the Martinsons Group in 1996.

In 2003, Martinsons began production of CLT Wood and developed its own framework system based on the new product. In the same year, Martinsons purchased  Wallmarks Såg AB in Kroksjön - a sawmill company which had been in operation since 1925. At the same time, Martinsons also became the sole owner of   Svenska Träbroar AB, of which it had been a 50 per cent owner since 1998. Svenska Träbroar was established in 1993.

In 2005, a new sawmill was built for SEK 225 million in Bygdsiljum, making it Europe's most modern once again. The group's structure was also simplified and the Martinsons trademark updated.

In 2007, Martinsons' sales surpassed the SEK 1 billion-mark for the first time. SEK 65 million was invested in the mill at Kroksjön.

In 2008, investment has countinued with the sawmill at Hällnäs.
