Solar Rooftop Mounting Structure with Hanger Bo...

The TOPEnergy Hanger Bolt System is the go-to solution for installing solar panels on roofs where standard clamps cannot be used, such as fiber cement (corrugated) roofs, sandwich panels, or older metal roofs requiring deep fixation. By anchoring directly into the roof's substructure (wood rafters or steel purlins), this system guarantees exceptional structural stability.

Each hanger bolt comes equipped with a high-quality EPDM rubber seal and a flange nut. When tightened, the rubber compresses against the roof surface, creating a permanent barrier against rain and moisture.

The kit typically includes the stainless steel hanger bolt (SUS304) and a pre-assembled L-foot. This design allows installers to quickly align the aluminum rails, significantly reducing installation time on difficult roof surfaces. The double-thread design also offers vertical adjustability to compensate for uneven roof decks.
