Profile Code and Reinforcement: The document outlines the profile code JF18041 and its reinforcement specifications. It includes dimensions in millimeters for different profiles and their respective maximum spans.

Dimensions: The profiles are specified with dimensions such as 40 x 20 x 2 mm and 30 x 30 x 2 mm. Another variant, JF18041-165x30, is detailed with dimensions of 165 x 30 x 2 mm.

Maximum Spans: The document provides maximum horizontal and vertical spans for each profile. For example, the 40 x 20 x 2 mm profile has a maximum horizontal span of 1700 mm and a vertical span of 1800 mm. The JF18041-165x30 profile can reach spans of 3000 mm both horizontally and vertically.

Considerations for Span Calculations: The maximum spans are calculated considering a maximum permanent deformation due to own weight of 2.5 mm and a maximum non-permanent deformation of 30 mm under a standard wind load of 150 kg/m². The standard aluminum reinforcement thickness is 2 mm, but greater thicknesses can allow for greater spans.
