At Koskisen, the wood’s journey from the forest to high-quality sawn timber is in the hands of the company’s experts from start to finish. The softwood we use is procured from sustainably managed forests. Koskisen’s sawn goods offer a broad range of sizes with superior dimensional stability. Further processed sawn goods are used extensively in the construction of buildings.

Sawmill industry
The Sawmill segment produces both standard sawn timber and dimensioned and strength-graded sawn timber from spruce and pine. About 40 per cent of sawn timber is further processed by planing and, to a lesser extent, painting. Koskisen also sells significant sawn timber and processed products to markets outside Finland, especially Japan.
Genuine Koskisen timber sports the KKN stamp
Koskisen’s shipping mark, KKN, is known far and wide as a sign of high-quality spruce and pine timber made to exacting standards. We manufacture our KKN stamped sawn goods from high-quality Finnish timber precisely and without compromising on quality. Sawing, drying and grading are carried out according to certified quality management systems. Koskisen’s strength graded timber also fulfils the requirements for CE marking.

Nordic J Products
Intorducing Nordic J, an exciting new choice in dimensional lumber, used extensively in 2×4 residental construction. Nordic J comes from Koskisen, a leading Finnish timber spplier with a reputation for quality products, that has recently been granted JAS certification.
