1. Excellent material performance
High strength and deformation resistance
The aluminum frame improves the overall structural strength through integrated design, with a tensile strength of ≥180 MPa, which can carry large component loads and reduce the risk of impact deformation .
The hardness of 6061/6063 aluminum alloy can reach more than 12HW, which is suitable for high wind pressure and high load scenarios .
Corrosion resistance and long life
Anodizing treatment forms an oxide film of more than 15μm, combined with nano-coating technology, the salt spray corrosion resistance life can reach 30-50 years .
The natural oxide layer of aluminum can resist galvanic corrosion and avoid micro-current corrosion problems caused by contact with steel brackets .
2. Lightweight and cost-effective
Lightweight and efficient
The density of aluminum is only 2.7 g/cm³, which is about 2/3 lighter than stainless steel, reducing transportation and installation costs, while meeting the load-bearing requirements of rooftop photovoltaics .
The thin-wall lightweight technology can reduce the frame wall thickness to 1.2mm and reduce the weight of the component by 18% . Convenient processing and installation
Aluminum profiles can be quickly customized with complex interfaces (such as angle brackets and guide rails) through CNC processing, adapting to different component sizes, and the tolerance can be controlled within ±0.1mm.
The snap-on design supports non-destructive disassembly and assembly, and the installation efficiency is increased by more than 30%.
3. Functional integration and environmental compatibility
Conductive and lightning protection functions
The aluminum frame has excellent conductivity and can be used as a lightning protection device to conduct weak currents and improve the safety of the photovoltaic system.
