At present, we manufacture and sell impregnated products such as power line poles, sleepers, fence posts and various special products such as jetties, stone caissons and piles. NTR is short for the Nordic Wood Protection Council and is a quality stamp to certify that our impregnated products have the right amount of uptake for the specific quality requirements for the products. NTR is a unique quality system in the wood protection industry and quality is ensured by an independent certification body which inspects our facilities several times a year.
