Wind load and permissible panel sizes

ALUCOBOND^® plus 4 mm

The graphs for 4 mm thick ALUCOBOND^® plus indicate the maximum permissible panel length (σ = 53 N/mm²) (without having to add a stiffener) based in applicable design wind load and panel width. Values apply to 4-side supported panels. Values for other systems on request.
