The sections below (A, B, C, D and E) all needed to be bolted together and filled with JB Weld. A 10mm expansion gap had to be maintained between each of the sections to allow for expansion and contraction of the roof structure. JB Weld is perfect for this job because it can handle 514kg per cm2 (half a ton on a square cm) of flex.
In total 150 boxes (JB Weld professional) were used. It was not an easy job, when you see the size of the flanges.
