Everest Solar Systems for trapezoidal sheet roofs without fixing the substructure are fixed with self-tapping sheet metal screws in the high beading.
Our XPressRail system is the classic choice, which is suitable for nearly all trapezoidal metal roofs at a minimum of 26 gauge.
The newest system MiniRail XPRess system is our first short-rail (railless) system for trapezoidal metal roofs. The self-taping screws are the same from our original XPressRail system and can attach to metal roofs at a minimum of 26 gauge. Special order screws are available to reach a minimum of 29 gauge metal roofs.
