Take into account the future stress caused by long term use. Nails, screws and angle irons made of stainless steel must be used to install impregnated timber in bearing structures and in structures that require absolute safety, such as stairs and railing.
In other structures, hot-dip galvanized products are also suitable (minimum thickness of the galvanization 90 μm). Jointing materials used together should be made from the same material. Stainless and hot-dip galvanized products must not come into contact with each other. Weatherproof adhesives are recommended for gluing.
