✔ Utility-scale Photovoltaic park
06 Advantages
▶ High-Strength Material Configuration:
Depending on specific site soil conditions and load requirements, we strategically select from Hot-Dip Galvanized Steel or advanced Zn-Al-Mg coated steel (MAC/ZAM). Our structural members employ optimized profiles—C/U steel, round/square tubes—to balance stiffness and weight, ensuring minimal deflection under 60m/s wind loads and 1.4 kN/m² snow loads.
▶ Robust Screw Pile Foundation:
The foundation integrates deep galvanized screw piles, providing superior pull-out resistance and stability in soft ground. This eliminates the need for extensive concrete curing, ensuring immediate load-bearing capacity upon installation, which is critical for rapid project timelines.
▶ Compliance with Global Engineering Codes:
Every component is designed and validated against a suite of international structural standards, including EN1990:2002, ASCE7-05, AS/NZS1170, and GB50017-2017, guaranteeing engineering safety and bankability for global investors.
▶ Multi-Layer Corrosion Resistance:
Leveraging materials like Stainless Steel SUS304 for critical connections and hot-dip galvanized/ZAM-coated main structures, the system offers a robust defense against corrosion in high-humidity or saline environments, backed by a 10-year warranty.
07 Technical verification system
Provide standardized installation videos, operation manuals and on-site technical guidance to ensure zero error in construction.
▶ Extreme environmental testing
• Pass the low-temperature impact at -40℃
• Salt spray corrosion (3,000 + hours)
• Extreme tests such as 60m/s hurricane simulation.
▶ Third-party certification
• We hold wind pressure, snow pressure, seismic resistance and material certification certificates issued by TUV, SGS and other institutions to ensure the compliance of global projects.
