Wind load and permissible panel sizes




The above diagrams indicate the available ranges of panel thickness and permissible range lengths at a given panel width (1250 or 1500 mm), depending on the loads applied.
The diagramms apply to panels supported on four sides (corners fixed). Dimensional values for other systems are available on request.
