Solar fasteners suffer long-term exposure to harsh outdoor climate. Professional anti-corrosion treatment and standard installation improve service life and safety performance of photovoltaic power stations.
| Treatment Technology | Corrosion Resistance | Applicable Scene | Service Life |
| Hot Dip Galvanizing | High anti-corrosion | Large ground solar station | Over 20 years steady use |
| Dacromet Coating | Super salt spray resistance | Coastal corrosive PV project | Long protection in harsh condition |
| Stainless Steel Passivation | General anti-rust | Residential rooftop solar system | Stable daily outdoor operation |
Regular inspection on fastener surface, replace damaged parts timely. Recheck connection points after extreme weather to eliminate safety risks.
