The diagram demonstrates the permissible lengths of 3mm *ALUCODUAL®* for a range of panel widths under varying wind loads. This data applies to panels supported on all four sides with fixed corners. The chart outlines lengths from under 2000mm to over 6000mm, adjusting for wind loads from 0.5 kN/m² up to 4.5 kN/m². The colours represent different widths, with specific trends for 500mm, 750mm, 1000mm, 1250mm and 1500mm, indicating a decrease in permissible length as wind load increases. _Information on dimensions for other systems is available upon request._
