Solar Hanger Bolt for Steel

The Hanger Bolt for Steel Purlins is a specialized fastener designed for securely connecting commercial/industrial rooftop photovoltaic (PV) mounting rail to steel structures like C‑purlins, Z‑purlins, and square tubes etc. Manufactured from carbon steel to achieve high-strength grades such as Grade 8.8, ensuring excellent tensile and yield strength to meet demanding mechanical requirements. Surface‑finished with high‑performance coatings like Zinc‑Nickel Alloy Plating, providing far superior corrosion protection.

Key Advantages

1, Rapid Installation, Cost Savings:

Installation requires only standard hand or power tools which significantly reducing installation time, labor costs, and safety risks

2, Reliable & Secure Connection:

Forms a robust metal‑to‑metal joint with the steel structure, offering excellent pull‑out and shear resistance to withstand extreme weather conditions (e.g., high winds, heavy snow).

3, Exceptional Durability & Low Maintenance:

High‑strength carbon steel base material ensures long‑term mechanical stability.

Zinc‑nickel alloy coating provides extended corrosion protection, dramatically reducing maintenance or replacement needs due to fastener corrosion, thereby lowering the total lifecycle O&M costs of the solar plant.
