There are many kinds of preservative wood in the market, such as Finnish wood, Pinus sylvestris, Southern pine, pineapple lattice, etc. There are many varieties of these woods, and there are different specifications of wood under the same kind of wood, for most people who don't know much about wood, how to distinguish between them? Usually what we call Finnish wood actually refers to Nordic pine timber that has been treated with preservatives, mainly from Finland, Russia, Northeast China and other places. Finland is the country with the highest forest cover in Northern Europe, and it was also the first country to introduce preserved pine to China, so it is customary to call it "Finnish wood".
Nordic pine has excellent structural properties, uniform and fine grain, and excellent quality. Scots pine grows slower in cold regions, has a compact wood, low fat content, clear fiber grain, small knots, and has higher strength than most softwood species. As artificially preservative wood, Finnwood is treated with ACQ preservatives under pressure and outdoor preservatives with KDAT (secondary kiln drying). After vacuum degreasing, the water-soluble preservative ACQ is poured into the closed high-pressure chamber, so that the preservative juice fully penetrates into the deep cells of the wood, giving the wood the functions of anti-fungal, anti-rot, anti-termites and other parasites, and at the same time has high density, high strength, good nail grip force, clear texture and decorative effect.
However, there are many products on the market that pass off as Finnish wood. To accurately identify real Finnish wood, you can start from the following aspects:
See whether there is a brand logo, whether the size is sufficient, whether it is imported dry wood, and whether it is treated with anti-corrosion according to national requirements. Genuine Finnish wood imports are accompanied by certificates such as certificates of origin, animal and plant quarantine certificates, import declarations and entry quarantine clearances.
Finnish wood is produced according to European standards, and importers usually provide ISO9001, ISO14001, PEFC and other certifications.
Finnish wood is available in a variety of sizes and lengths from 33 m to 6 m per 03 meters a promotion, and the size is sufficient.
Finnish wood uses environmentally friendly preservatives, the preservative treatment level is Class A, and no CCA preservatives containing chromium and arsenic are used.
These points can help consumers to accurately identify Finnish wood in the market and ensure that they are buying high-quality preservative wood.
