Long Rail (60 mm Height)

The Long Rail is the primary structural backbone of our mounting system. This robust 60 mm profile provides exceptional strength and rigidity, making it ideal for installations requiring longer spans or greater load-bearing capacity. Its substantial height helps the system achieve a total roof clearance of up to 120 mm, ensuring maximum airflow beneath the panels for optimal performance and easily accommodating uneven roof surfaces.

Long Rail (40 mm Height)

Our 40 mm Long Rail offers a strong and reliable foundation for standard solar installations where a lower profile is desired. It provides a sleek, discreet appearance while helping the system achieve a roof clearance of up to 100 mm. This ensures sufficient ventilation for panel efficiency while delivering the structural integrity needed to securely support the solar array for decades.

Unified U Cleat

The Unified U Cleat revolutionizes the installation process with its innovative snap-fit system. This design allows the long rail to be effortlessly snapped into place, eliminating the need for the separate nuts and fasteners required with traditional L-cleats. Furthermore, its unique 'U' shape provides crucial support to both sides of the long rail, offering superior stability and load distribution.

External Rail Nut

Engineered for a perfect fit, the External Rail Nut is a specialized fastener that slides into the channels of our long rails. It provides a secure and adjustable locking point for attaching other components, such as cleats and clamps, ensuring a tight and reliable assembly with exceptional pull-out resistance.

End Clamp

The End Clamp is used at the beginning and end of each row of solar panels. This component is crucial for securely fastening the first and last panels in the array to the mounting rails. Its design ensures a firm, even grip on the panel frame, protecting it from stress while holding it firmly in place against wind and other environmental forces.

Mid Clamp

Positioned between two adjacent solar panels, the Mid Clamp simultaneously secures both panels to the mounting rail. This shared clamp not only creates the proper spacing between modules for a uniform look but also provides a strong, balanced hold that distributes pressure evenly across the panel frames, ensuring the entire array is locked together as a single, solid unit.

M8 Allen Bolt Set for Module Mounting

Crafted from high-grade SS-304 stainless steel, this bolt set is used with our clamps to securely fasten your solar modules to the long rails. The 25 mm length is perfectly sized to provide a tight, reliable grip on the module frame, ensuring a corrosion-resistant and secure installation that lasts for decades.

M8 Allen Bolt Set for Rail Mounting

Engineered from premium SS-304 stainless steel for maximum durability, this heavy-duty bolt set anchors the long rails to the Unified U-Cleats. Its 60 mm length provides the necessary reach to create a powerful, corrosion-resistant clamping force, locking the rail firmly into the system's foundation for maximum stability and strength.

M6 SDS Self-Driven Screw

The M6 SDS Self-Driven Screw is the critical anchor that fastens the entire mounting system to the building's structure. Its powerful self-drilling tip is designed to drive directly into the purlin beneath the roof surface, securely fixing the Unified U Cleat in place. This provides the essential pull-out strength needed to keep the solar array safe and stable.

EPDM Rubber Pad

The EPDM Rubber Pad is a vital sealing component that ensures your roof remains completely waterproof. Placed between the Unified U Cleat and the roof surface, this durable pad creates a long-lasting, weather-tight seal. It effectively prevents any water leakage at the mounting points, protecting your property and giving you total peace of mind.

Frequently Asked Questions (FAQ)

Answers to common questions about the Unified X Long Rail.

1. What type of roof is the Unified X Long Rail system designed for?

The system is specifically designed for installation on a Trapezoidal Metal Roof. This is a critical specification, as the mounting components are engineered to align with the roof's high ridges and lower pans, ensuring a secure and weather-tight attachment directly to the structure.

2. Can I use this system with unframed (frameless) solar modules?

This system is specified for use with a Framed module. Its clamping mechanisms are designed to securely grip the aluminum frame of a standard solar panel; frameless modules require different types of clamps with rubber padding to avoid damaging the glass.

3. What is the maximum wind speed this system can handle?

The Unified X Long Rail is engineered for a designed wind load of Upto 200 km/h. This high rating makes the system a suitable choice for areas with significant wind exposure, though a project-specific engineering review is always necessary to ensure compliance with local codes.

4. What materials are used for the rail and fasteners?

The system is manufactured from Aluminum 6063-T6 with SS-304 Fastners. This combination is an industry best practice; the aluminum offers an excellent strength-to-weight ratio and high corrosion resistance, while the stainless steel fasteners prevent galvanic corrosion, ensuring the long-term durability of the entire assembly.

5. Does the system support different module orientations?

Yes, the system is highly versatile, it is Suitable for both portrait and landscape module orientations, allowing designers to optimize the array layout for any project.

6. What makes the installation process faster than other systems?

The system features a Simplified installation with pre-drilled holes for quick assembly, reducing labor time and costs. This level of preparation minimizes the need for on-site drilling and measurements, streamlining the entire workflow for installation crews.

7. Why is the "no-tilting" feature of the U-Cleat important?

The secure U-Cleat installation ensures perpendicular load distribution to the center of the clamp, effectively eliminating any tilting issues. This is vital because uneven pressure on a module's frame can cause invisible microcracks in the solar cells, which degrades the panel's performance and shortens its operational lifespan.

8. What are the main advantages of using a "long-span" rail system?

This system is described as Ideal for long-span solar installations. A rail with a long-span capability can bridge a greater distance between roof attachment points. This provides two key advantages: it reduces the total number of roof penetrations required, which saves labor and lowers leak risk, and it decreases the overall amount of mounting hardware needed for the project.

9. What is the clearance height and why does it matter?

The system provides a module-to-roof clearance of 100 to 120 mm Height. This specific gap is essential for passive cooling, as it allows air to circulate freely underneath the solar panels to dissipate heat. Maintaining lower operating temperatures is key to achieving higher panel efficiency and greater overall energy production.

10. How is the system anchored to the roof structure?

The specified anchoring methods are Bolting, SDS. This indicates a robust mechanical attachment. "Bolting" refers to securing the mounts directly to the roof's structure (like purlins), while "SDS" suggests compatibility with heavy-duty tools for a strong and reliable foundation.
