How to Specify PV Fastener Materials by Site Environment
The most common cause of premature hardware failure on solar sites is not undersized bolts — it is a material mismatch with the corrosion environment. Based on our experience supplying projects in varied climates, this quick reference helps you shortlist materials before requesting a proposal.
Corrosion categories follow the widely used ISO 9223 classification (C1 very low to C5 very high). Final selection should always be confirmed by your structural engineer.
Galvanic corrosion tip: when stainless steel bolts clamp aluminum rails, use isolating washers (EPDM or nylon) to limit contact between dissimilar metals in wet environments.
| Site Environment | Typical Category | Commonly Specified Hardware |
|---|---|---|
| Inland rural / desert | C2 – C3 | Hot-dip galvanized carbon steel or 304 (A2) stainless; anodized aluminum rails |
| Urban & commercial rooftop | C3 | 304 (A2) stainless bolts, nuts and washers with aluminum rail systems |
| Industrial zones | C4 | 316 (A4) stainless or heavy-coating galvanized steel; sealed connections |
| Coastal & offshore | C5 | 316 (A4) stainless fasteners; isolating washers at all aluminum interfaces |
| Concrete foundations | Varies | Stainless expansion bolts or anchor bolt sets sized to design pull-out loads |

What products does Youlong manufacture?
We manufacture photovoltaic mounting components — aluminum guide rails, water channels, angle brackets and connectors — plus precision fasteners including anchor bolts, carriage bolts, expansion bolts, flat washers and wing nuts for solar, wind power and construction projects.
Can you produce custom PV brackets and fasteners to my drawings?
Yes. Our automated stamping, forging and CNC machining lines support OEM and custom production. Send drawings or samples with material, finish and quantity requirements, and our engineers will confirm feasibility, tolerances and a written proposal.
How do you control quality for outdoor solar projects?
We run random inspections from raw material intake to final dispatch and test against industry standards, including salt spray corrosion testing and tensile strength testing, so hardware performs reliably under long-term outdoor exposure.
Which material should I choose for coastal or high-humidity sites?
For coastal, offshore or industrial sites, 316 (A4) stainless fasteners are generally recommended. For inland sites, 304 (A2) stainless or hot-dip galvanized carbon steel is commonly specified. Isolating washers help prevent galvanic corrosion between aluminum rails and steel hardware.
Where are you located and do you export worldwide?
We are located in Yongnian District, Handan City, Hebei Province — China's Fastener Capital. We have served more than 100 clients worldwide, with cumulative shipments exceeding 300,000 tonnes.
