Certified Manufacturing
Our purlins are UL 2703 certified and are built to hold solar modules in both Canada and USA applications.
Per UL, "Proper grounding of a photovoltaic (PV) power system is critical to helping ensure electrical safety during its lifetime. PV equipment needs to be properly bonded, in addition to code-compliant grounding, so that the low current flows on metal parts can facilitate the operation of over current and ground-fault protection devices.
UL 2703, the Standard for Mounting Systems, Mounting Devices, Clamping/Retention Devices, and Ground Lugs for Use with Flat-Plate Photovoltaic Modules and Panels covers mounting systems, including mounting devices, clamping devices and ground lugs for use with photovoltaic modules and panels and contains requirements for ground- mounted and roof systems as part of a nonstructural building component."
