Design Information
All testing and design of Spacedek have been performed in accordance with the relevant Australian Standards. This includes testing for both concentrated loads and wind forces.
Maximum allowable deck overhang 900mm with stiffened edge.
Spans of 4.4 metres are achievable when using Spacedek in a carport, verandah or awning situation for Region A - Category 3 (densely populated, residential) locations.
