The combination of hanger bolts and rails in solar mounting systems is a crucial component used to install solar panels on rooftops. They provide secure connections and support, ensuring the safety and stability of solar panels under various environmental conditions.
1. Hanger Bolt:
A hanger bolt is a fastener with a double-thread design: one end has wood threads, and the other end has machine threads. Typically, the wood-threaded end is inserted into the wooden structure of the roof, while the machine-threaded end is used to connect the mounting rails or other fastening components.
Wood-threaded end: This part is embedded into wood or wooden structures, providing strong grip and stability.
Machine-threaded end: This part is used to secure the rail or mounting components with nuts or other fasteners.
2. Rail:
The rail is the primary support component of the mounting system, used to secure the solar panels. Rails are usually made of lightweight, corrosion-resistant materials such as aluminum alloy. They can be adjusted in length as needed and are fixed to the solar panels and other mounting components using pre-drilled holes.
Connection: The hanger bolt’s machine-threaded end connects with the rail, ensuring a secure attachment between the rail and the roof structure.
Support: The rail provides horizontal support for the solar panels, while the hanger bolt helps to secure the connection between the rail and the roof.
Corrosion resistance: Both the hanger bolts and rails are typically made from corrosion-resistant materials (e.g., galvanized steel or aluminum alloy), effectively withstanding harsh weather conditions and extending the system's lifespan.
Applications:
This combination is widely used in solar rooftop mounting systems, particularly in residential and commercial solar photovoltaic systems. It ensures the solar panels are firmly installed and can withstand external pressures like wind and snow loads.
