The wall elements of parkour structures are made of sustainable cross-laminated timber (CLT) to ensure high stability and durability despite constantly changing atmospheric humidity. A four-stage treatment process has been employed to make the wood weatherproof. The top edges of wall elements are covered with rubber coated anti-slip plastic which comes in two colour options: grey or red. Horizontal pipes are made of stainless steel and the vertical posts of hot-dip galvanized and powder coated steel. The structure is meant to be fixed on surface (e.g. 150mm reinforced concrete slab foundation). Ground fixings are made of hot-dip galvanized metal.
