Solar Rooftop Mounting Rail
Alument Industries manufactures high-strength aluminium mounting rails specifically designed for rooftop solar panel installations. Our rails are extruded from 6063-T5 aluminium alloy with an anodized surface finish, providing a robust and corrosion-resistant foundation for residential, commercial, and industrial rooftop PV systems. Each rail features an integrated T-slot channel that accepts standard mid clamps, end clamps, and splice connectors for rapid, tool-friendly installation. Our rooftop mounting rails are available in both horizontal and vertical configurations to suit portrait and landscape panel orientations. The optimized cross-section design delivers a high moment of inertia relative to weight, enabling longer span distances between roof attachments while maintaining structural integrity under wind uplift and snow loads as per IS 875 (Part 3) requirements. Every rail undergoes rigorous quality testing including dimensional tolerance checks, anodization thickness measurement, and mechanical property verification. Our rails are compatible with all major solar clamp brands and can be supplied pre-cut to project-specific lengths, reducing on-site waste and installation time for EPC contractors.
