Pressure-treated structural timber, NTR A

We offer structural timber in various dimensions, ideal for building a robust substructure for a freestanding deck.

When planning to build a freestanding deck, shed or other outdoor structure, choosing the right materials is essential for long-term performance. Pressure-treated timber provides the durability, stability and protection required for demanding outdoor construction projects.

At Norra Timber, we place great emphasis on timber quality because we know it is critical to the success of every build. Manufactured from Northern Swedish spruce, our pressure-treated timber helps create strong, reliable and long-lasting structures that stand up to Nordic weather conditions.

Top environmental assessment rating

The close annual rings in our northern Swedish pine, which contains a high proportion of heartwood, mean that very little preservative solution penetrates our products. Instead, it is primarily the heartwood’s natural resistance to decay that protects Norra Timber products, reducing the amount of preservative required. As a result, we receive the highest ratings in the various environmental assessment systems, and our in-house treatment process has the lowest environmental impact rating according to Byggvarubedömningen.

We can supply green pressure-treated timber in accordance with the Nordic Wood Preservation Council’s requirements in all the most common construction dimensions and product types: decking, exterior cladding, structural timber, posts and handrails.

About wood preservatives

The wood preservatives used in Sweden are carefully controlled and approved by the Swedish Chemicals Agency and regulated under the EU Biocidal Products Regulation to ensure minimal environmental impact.

The solution used for pressure treatment contains copper salts, the same type of substances used in antifouling paints to control algae. Copper is an essential metal for both people and the natural environment, but at excessive concentrations it can be toxic to aquatic organisms. However, the pressure-treatment solution contains less than four grams of copper per linear metre of timber.
