Product Summary

Longze Adjustable Triangle Solar Brackets are high-strength racking systems designed for optimal solar panel positioning on flat roofs and ground installations. Manufactured in

Yongnian, China, our brackets utilize structural-grade AL6005-T5 Aluminum, offering an exceptional strength-to-weight ratio and superior corrosion resistance. Whether for a

residential flat roof or a utility-scale solar farm, Longze triangle brackets provide the adjustable tilt angles (10°–60°) required to maximize solar harvest throughout the year while withstanding extreme wind and snow loads.

• ✔ High-Strength AL6005-T5: Unlike lower-grade alloys, our T5 tempered aluminum ensures structural rigidity and a service life exceeding 25 years in harsh outdoor environments.

•  

• ✔ Telescopic Adjustability: The rear leg features a telescopic design, allowing for precise tilt angle adjustments ($10^\circ$ کو $60^\circ$) to match the specific latitude and seasonal variations of your project site.

•  

• ✔ Rapid Pre-Assembly: Every bracket kit is partially pre-assembled in our factory, significantly reducing onsite labor costs and installation time.

• Standards: AS/NZS 1170, JIS C 8955:2017, Eurocode 3.

•  

• Tilt Angle: Fixed ($10^\circ, 15^\circ, 30^\circ$) or Adjustable ($10^\circ$ - $60^\circ$).

•  

• Wind Load: Up to 60 m/s.

•  

• Snow Load: Up to 1.4 KN/m².

•  

• Material: Anodized Aluminum AL6005-T5 & Stainless Steel 304 Fasteners.

•  

• Anodizing Thickness: Average 12-15 $\mu$m (Standard) or 20+ $\mu$m (Coastal).

Avoid Pitfalls:

• Thin-Walled Failure: Many low-cost brackets use 1.2mm profiles that buckle under high wind. Longze strictly utilizes ≥ 2.0mm or 3.0mm wall thickness based on local wind load requirements to ensure stability.

•  

• Dissimilar Metal Corrosion: We provide Stainless Steel 304 fasteners and EPDM rubber gaskets to prevent "galvanic corrosion" between the aluminum bracket and the roof surface.

•  

• Loose Pivots: The rotating joints of triangle brackets are the most common fail point. Longze uses flanged stainless steel bolts with serrated nuts to ensure the tilt angle remains locked for decades.

•  

Perfect Fit Assembly:

• Universal Compatibility: Our triangle brackets are designed to work seamlessly with Longze Solar Rails, Mid Clamps, and End Clamps, creating a unified structural ecosystem.

•  

• Ballast or Anchor: These brackets can be bolted directly into concrete pads using Longze Expansion Bolts or used with ballast trays for non-penetrative roof installations.

•  

Quality Control & Logistics:

• ISO 9001 Certified: 5-step QC including alloy spectrometer analysis, anodizing thickness measurement, and structural load simulation testing.

•  

• Sea-Worthy Packaging: Brackets are stacked with protective foam layers, bundled in reinforced master cartons, and palletized to prevent scratching during international maritime transit.

• Q: What wind speed can your adjustable brackets handle? A: Our standard design handles 45 m/s. For hurricane-prone areas (like Florida or the Philippines), we can provide reinforced 3.5mm thick profiles rated for 60 m/s.

• Q: Are these brackets suitable for portrait or landscape orientation? A: They work for both. The spacing between triangle sets is adjusted based on the panel orientation and the rail length.
