====OVERVIEW====
The Snap Lock II 675 Panel is an on-site continuous panel metal roofing machine. Panel profiles vary from 300 mm (12") to 500 mm (20") wide with a seam height of 44 mm (1-3/4"). 

On-site roll forming provides for the elimination of end laps with continuous panel forming capabilities in lengths up to nominal 46 m (150&#8217;).

====SYSTEM DESCRIPTION====
#'''General''': The SS675 44 mm (1-3/4") Snap-Lock profile is a snap lock concealed fastener roofing panel. The panel can be formed in any width between 300 mm (12") and 450 mm (18"). Stiffening ribs, striations and / or clip relief can be added depending on the application. The male leg locks along the entire length of the panel and does not rely upon clips to provide additional locking. The SS675 utilizes 153 mm (6-1/8") of metal in forming the panel legs providing greater structural integrity, which can carry greater loads.
#'''Range of application''': on wood or metal sloped roofs; in commercial, institutional, industrial and residential construction; for re-roofing or new construction.
