Frequently Asked Questions
Find technical insights, compliance details, and supply chain answers about Ziyuan Solar mounting systems.
What materials are used in Ziyuan Solar mounting systems?
We primarily utilize high-strength Aluminum Alloy AL6005-T5 for our structural rails and clamps, Stainless Steel SUS304 for all fasteners, and Hot-Dip Galvanized Carbon Steel Q235B (zinc coating thickness ≥ 85μm) for ground screw piles. This material matrix ensures an optimal balance of structural lightweighting and lifetime durability.
Are your mounting structures certified by independent third parties?
Yes, all core Ziyuan products are fully tested and certified by SGS. Our bankable technical documentation includes official SGS test reports for Ground Screw Torsional Tests, Ground Screw Pull Tests, Aluminum Profile Neutral Salt Spray Tests (96H/500H), and Roof Clamp Mechanical Pull Tests. These reports are available for direct download in our Resource Center.
Which international engineering standards do you follow for wind and snow loads?
Our structural engineering team strictly adheres to international baselines to guarantee project safety. We compute wind and snow loads based on JIS C8955:2017 (Japan), AS/NZS 1170 (Australia/New Zealand), Eurocode 1 (Europe), and IBC/ASCE 7 (USA). Systems can be custom-engineered to withstand extreme wind speeds up to 60 m/s.
Do you provide customized structural calculation reports and layout designs?
Absolutely. For every specific project, our internal engineering department provides comprehensive technical support at zero cost. This includes full 2D/3D AutoCAD layout drawings, ballast/penetration engineering maps, and project-specific Structural Calculation Reports. These PE-stamped documents are fully prepared for local utility grid-connection and lender financing audits.
What is the typical manufacturing and shipping lead time from Xiamen Port?
Strategically located in Xiamen—the global hub for solar racking logistics—we offer exceptional supply chain efficiency. Standard component and racking orders are manufactured and dispatched to Xiamen Port within 7 to 14 days. For large-scale utility megawatts requiring custom aluminum extrusions, the lead time ranges from 20 to 25 days.
Can Ziyuan Solar provide OEM/ODM customization for specialized metal roofs?
Yes. Customization is one of our core competencies. Whether your project involves unique trapezoidal corrugated sheets, standing seam roof structures, or specific sandwich panels, we can rapidly engineer and CNC-prototype customized adjustable metal roof clamps and bracket adapters tailored exactly to your roof profiles.
What warranty and lifespan do you guarantee for your mounting systems?
We provide a 10-year product warranty paired with a 25-year structural service life. This long-term reliability is backed by our specialized 11-step anodizing process, which maintains a uniform protective oxide film thickness of 15 to 20 microns (μm), securely mitigating pitting and galvanic corrosion in highly corrosive C4 and C5 marine environments.
