The panel joint rail options shown are based on a maximum panel length of 6m (longer panel lengths are available). The details provided are for guidance only and are intended to demonstrate the main principles which should be adopted.
For simplicity, panels and column centres should be compatible as shown.
Attention must be given to the maximum permissible horizontal span of the composite panel to be used without additional vertical supports being required.
A red arrow indicates to cleat bolts nearest to column face
A blue arrow indicates to cleat bolts nearest to sheeting face
