Wooden paths and wooden walkways are typical in coastal areas. They lead through often rough terrain or through sand dunes. If you look at the necessary wooden construction, you could say that wooden walkways are basically very long and very narrow wooden terraces, because they also consist of a load-bearing substructure and planks bolted to it made of weatherproof wood. Both are often installed in larger dimensions on bridges, so that the wooden planks can have thicknesses of 40-45 mm.
What are the challenges for fastening?
As with a wooden terrace, the fastening screws primarily secure the connection of planks and substructure against moving and lifting. In the case of woods of larger dimensions, the forces occurring as a result of the work of the wood are also greater. The screws used must therefore be more massive and longer. And finally, there is not only a particularly humid climate near the coast, the screws are often also exposed to splashing water from the sea and very salty air. This poses very special challenges for the corrosion protection of the fasteners.
