Solar Fastener for Solar Roof Mounting Bracket System

 

.Overview

Hanger Bolt(solar fasteners) is one kind of fixings with mounting structure used to screw into steel purlins or wooden rafter on corrugated and trapezoidal roofs. This creates a load-bearing connection between the building substructure and the PV mounting system. This mounting variant is particularly advantageous in regions with high wind loads. 

Hanger bolt is frequently used with L feet(L bracket) or stainless steel plate to combine with mounting rail.

The Hanger Bolt for solar panel installation is coming with three flange nuts and one UV resistant EPDM washer(gasket), the EPDM washer will prevent rainy day water leakage .

Mounting the brackets: remove the first nut (or nut + lock washer); set the desired mounting height of the angle with the second nut; position the bracket; screw on the first nut (tightening torque M8: 12–15 Nm, tightening torque M10: 20–25 Nm, tightening torque M12: 25–30 Nm). The maximum distance of the bracket to the roof covering must be observed.

Hangar bolts/solar fasteners can be used for direct connection to the roof substructure for the following roof coverings:

– Trapezoidal and corrugated sheets

– Corrugated fibre cement sheets

– Sandwich elements

– Flat roof coverings with bitumen or shingles
