The DT Rail Penetrative is a specialized component used in the installation of solar photovoltaic (PV) modules on pitched roofs. It is a type of rail system that is designed to penetrate through the roof surface and provide a secure and stable mounting base for the PV modules.

Key features of the DT Rail Penetrative:

Penetrative design: The rail is designed to penetrate directly through the roof surface, eliminating the need for additional support structures or flashing.
Secure attachment: The rail is typically attached to the roof rafters or joists using a combination of screws, brackets, and flashing to ensure a secure and weather-resistant installation.
Durability: The rail is typically made of a durable material, such as aluminum or stainless steel, to withstand harsh weather conditions and provide long-lasting support.
Compatibility: The DT Rail Penetrative is designed to be compatible with various types of roof coverings, including tiles, shingles, and metal roofing.
Benefits of using the DT Rail Penetrative:

Efficiency: The penetrative design eliminates the need for additional support structures, simplifying the installation process and reducing costs.
Security: The rail is designed to provide a secure and stable mounting base for the PV modules, ensuring their safety and performance.
Weather resistance: The rail is typically treated or coated to resist corrosion and other environmental factors.
Aesthetics: The rail can be designed to blend in with the roof surface, minimizing visual impact.
Applications:

Rooftop solar installations: The DT Rail Penetrative is a popular choice for installing solar panels on pitched roofs, especially in areas with limited roof space or where ground-mounted systems are not feasible.
Residential and commercial buildings: The rail can be used in both residential and commercial solar installations.
