Product Summary

Longze Photovoltaic Brackets are high-performance mounting structures designed to provide maximum stability and longevity for solar energy systems. Whether for utility-scale ground mounts, industrial flat roofs,

or residential pitched roofs, our Photovoltaic Support Systems are engineered from premium AL 6005-T5 Aluminum et Hot-Dip Galvanized Steel, ensuring 25+ years of structural integrity under extreme wind and

snow loads.

• ✔ Engineering-Grade Materials: Available in high-tensile AL 6005-T5 for rooftop weight savings or Q235B/Q355B Steel for heavy-duty ground-mount cost-efficiency.
  
  

• ✔ Advanced Anti-Corrosion: Features 12μm+ Anodization ou 65μm+ Hot-Dip Galvanizing, providing a superior sacrificial barrier against oxidation in coastal and high-humidity environments.
  
  

• ✔ Modular Fastening Design: Fully optimized for use with DIN 6923 serrated flange nuts, allowing for rapid, tool-free alignment and massive reductions in on-site installation time.

Surface Treatment & Environment Testing

• Ensuring 25-year structural integrity for Solar Support Systems.

• Coating Type	Process	Thickness / Test	Best Application
  Hot-Dip Galv.	Molten Zinc	65μm - 85μm	Utility-Scale Ground Mount
  Clear Anodized	Electrolytic	12μm+ / 1000h Salt	Residential / Commercial Roof
  ZAM Coating	Alloy Coating	1500h Salt Spray	Coastal / High-Ammonia Zones

Avoid Pitfalls:

• Inadequate Zinc Coating: Pour Supports photovoltaïques used in ground mounts, anything less than 65μm HDG will lead to structural rust within 5-10 years. Always verify coating thickness with a magnetic gauge.
  
  

• Mixing Metal Types: Do not mount aluminum rails directly to galvanized steel brackets without an isolation gasket. This prevents galvanic corrosion which can compromise the entire racking system.
  
  

• Under-estimating Wind Load: Rooftop brackets must be calculated for specific wind zones. Using a "standard" bracket in a high-wind coastal area without additional bracing can lead to catastrophic system failure.
  
  

Perfect Fit Assembly:

• Vibration Resistance: Our system uses DIN 6923 Serrated Flange Nuts to ensure that once the bracket is torqued, it stays locked despite the constant micro-vibrations caused by wind.
  
  

• Thermal Expansion: For long rows of Supports photovoltaïques, ensure expansion joints are installed every 12-15 meters to prevent the rails from warping the module frames.
  
  

Quality Control & Logistics:

• ISO 9001 Certified: 5-step QC including Zinc/Anodizing Thickness Verification, Tensile Load Testing, et Component Fitment Verification.
  
  

• Export Hub Logistics: Bundled and kitted for rapid container loading. Strategic shipping from our Yongnian manufacturing base to minimize lead times.

Q: Do you provide structural calculation reports for specific projects? A: Yes, we provide technical data sheets and structural certifications to help engineers verify wind and snow load compliance.

Q: Can you customize the tilt angle for our site? A: Absolutely. We offer both fixed-angle and adjustable Supports photovoltaïques to optimize energy yield based on your latitude.
