The slats are made of larch wood. They are slightly grooved, which makes smaller scratches due to vandalism less visible. There are three lengths and three types of surface treatment from which to choose. The metal parts are made of hot-galvanised steel. They have a high-quality coating with a slight metallic pattern. Their colour is anthracite, similar to DB 703 metallic or RAL 7024. The individual elements are joined with safety screws. All elements can be replaced individually in case of damage due to vandalism.
