Martinsons have always based its success on different ways of refining the forests from northern Sweden. The slow-growing spruce and pine forests in the region of Västerbotten provides sawn timber with well-known high-quality and good construction characteristics. The long winters create dense annual rings which make the timber hard, form stable and resistant. Martinsons only take wood from the north Swedish sustainable forestry and the slow-grown timber underlies for the quality that Martinsons is known for.
