    At our beam design uses flange stiffeners for maximum beam strength. The batten bar attachment slot does not attempt to pre-form threads for screws that attach the batten bar to the beam, since a 6mm bolt thread pattern requires tolerances in excess of what can be extruded in aluminium. Instead this slot is sized for a thread rolling fastener that can be removed and installed multiple times in the same slot. The batten bar is designed as a leaf spring to compress the low memory set silicone gasket between the panel and the batten bar. The panel edge bend is designed such that when the batten is tightened, the panel is pushed into the gasket. This is the only batten system with three redundant features to ensure a leak free design. The batten legs are also designed to prevent twisting when personnel access the dome roof.


    The attempt to form threads in the beam at the extrusion mill is not practical due to normal extrusion process tolerance. A screw will strip out the threads in the slot after one or two installations and will not develop maximum strength. No flange stiffeners are allowed due to manufacturing limitations. The gasket compression is the sole device for sealing the joint
