Against the backdrop of an average annual growth rate of more than 20% in global photovoltaic installed capacity, aluminum profiles continue to replace traditional steel and become the mainstream choice for solar brackets with their comprehensive performance advantages.
Aluminum profile VS steel/stainless steel performance comparison
| Comparison items | Aluminum profile (6063-T6) | Galvanized steel (Q235) | Stainless steel (316L) |
| Density | 2.7g/cm³ (40% lighter) | 7.85g/cm³ | 8.0g/cm³ |
| Corrosion resistance | Salt spray resistance 3000h after anodizing | Galvanized layer is prone to rust after damage (lifespan 10-15 years) | High cost, still prone to pitting in chloride ion environment |
| Recycling value | Residual value rate exceeds 80% | ≤50% | 60%-70% |
Three major technological breakthroughs in aluminum brackets
Lightweight structure: The density of aluminium sections is only 1/3 of that of steel, reducing the weight of the bracket system by 40% and the cost of pile foundation by 25%; Intelligent connection design: snap-on/pre-installed node solution, installation efficiency increased by 50%; Low-carbon cycle: 100% recyclable, reducing CO₂ emissions by 6 tons/10,000 tons compared to steel manufacturing.
GNEE photovoltaic aluminum solution
GNEE's independently developed "weather-resistant anodized aluminum bracket" has passed TUV 2000-hour salt spray certification and has been supplied to global projects such as Brazil's 2.1GW photovoltaic power station. The patented quick-install structure can shorten the construction period by 30%. The company has 28 fully automatic solar panel aluminium extrusion production lines with an annual production capacity of 120,000 tons, and has simultaneously passed UL, CE and ISO 14064 carbon footprint certification.
