Hanger Bolt Solar Mount

Stainless Steel Solar Hanger Bolt M10/M12 for Metal Roof Mounting

Durable Solar Hanger Bolt Solutions for Tin and Metal Roofs Our Solar Hanger Bolts (also known as dual-thread bolts) are engineered to provide a secure and efficient mounting solution for PV systems on corrugated or trapezoidal metal roofs. Whether you are installing on wood rafters or steel purlins, our M10 and M12 hanger bolts ensure maximum structural integrity and long-term weather resistance.

Product Overview

The Hanger Bolt Solar Mount is a penetrating mounting solution designed for photovoltaic installations on trapezoidal and corrugated metal roofs.
It provides a strong mechanical connection to roof purlins while ensuring waterproof performance through reliable sealing components.

Super Solar’s hanger bolt solar mounting systems are widely used in commercial and industrial metal roof PV projects, metal roof solar mounting system, especially where standing seam clamps are not applicable.

When to Use a Hanger Bolt Solar Mount

Hanger bolt systems are recommended when:

• The metal roof profile does not support seam clamping

• Direct fixing to steel or wooden purlins is required

•  Higher load capacity is needed

•  Long-term structural reliability is a priority

They are commonly applied to steel sheet roofs with trapezoidal or corrugated profiles.

Compatible Roof Structures

Our hanger bolt solar mounts are suitable for:

• Trapezoidal metal roofs

• Corrugated metal roofs

• Steel or aluminum sheet roofs

• Roofs with steel or wooden purlins

Roof solar mounting system and layout confirmation are supported by our engineering team.
