Our production capabilities provide access to a complete range of products not only in terms of a variety of different sorts of products, but also dimensions, moisture content, quality and strength, as well as varying degrees of processing, such as preservative impregnation and painting.
Softwood is our raw material
Our products are made of softwood - spruce and pine. Spruce products feature excellent strength properties and are suitable for construction. Customers in the construction and do-it-yourself sector are the principal buyers of these products. Pine has good properties for carpentry and molding production but also packaging and impregnated products.
We produce wood products primarily for construction and housing-related purposes. We look to customers who demand high quality in terms of both products and delivery services.
We provide products such as studwork timber, battens, planed wood products, strength-graded wood, tongue and groove timber and boards, cladding and impregnated timber.
Approximately 70% of production is intended for high-grade construction materials. Sawn timber is manufactured in a range of lengths and dimensions. They consistently hold a quality that is adapted to customer specifications. Sawn and planed products can also be strength-graded and have various types of quality certifications.
In addition to offering high product quality, we provide a high degree of delivery reliability and short lead times. In recent years, we have developed customised logistics and IT solutions.
Raw material and grades for all needs
In our sawmills, the entire log is taken care of. Approximately half of the log
volume becomes sawn timber. The other half is provided to the paper industry and wood board industry. Bark, wood chips and sawdust are also sold to the
biofuel sector or used as energy in the sawmill. All Södra industries are self-
sufficient in energy by utilizing the waste products.
The fresh wood moisture content varies between 30% and 160%. To be able to be
stored without any quality loss the timber is dried below a 20% moisture level. The wood is dried to usually an average moisture content
The quality of the timber can be specified with a large number of parameters, such as: knots with resin galls, fungus caused twist, discoloration, crookedness, cracking, bark draws, top fracture, fatwood deformation, handling damage, dull edge, pout, wood compression, and size deviation.
The wood is sorted into six categories, where I represents the highest quality.
The varieties I-IV gather, according to industry standards, known as O/S and represents the highest quality. The lowest sorting rate — VII or reject are comparable to D, where all timber defects are allowed without restrictions, however the wood piece must hold together.
Timber for bearing construction is using timber sized by factors of structural strength, mainly knots, but also twist, fungus, plant, cracks and holes, and form. For evaluating the significance concerning the strength, there are clear rules that specify how the knot size should be measured and how they should be assessed:
- size relative to the size of the timber
- placement edge side / flat side
- position in the timber’s longitudinal direction.
The timber is divided into classes according to C35-C14, where C14 is the lowest
strength. We use both mechanical and visual sorting.
