Application Challenge: Providing long-term reliable connection and foundation anchoring solutions for tracker or fixed-tilt support systems in large-scale ground-mounted solar farms. Fasteners must operate continuously for over 25 years in harsh outdoor environments (exposure to sun, rain, snow, sand, and salt spray), possessing exceptional corrosion resistance, UV aging resistance, and the ability to withstand long-term fatigue stress from dynamic loads like wind and snow.

HaoSheng Solution: Supplied a "PV Mounting-Specific Fastener Kit" consisting of U-bolts, clamp bolts, anchor bolts, and matching lock nuts made from hot-dip galvanized steel (compliant with ISO 1461) or aluminum-magnesium alloy. For coastal or highly corrosive environments, a higher-grade stainless steel option (e.g., A4-70/A4-80) is offered. All products undergo rigorous salt spray testing and mechanical property testing to ensure superior weather resistance and stable clamping force, effectively preventing connection failure due to corrosion or vibration, thereby safeguarding the structural integrity and power generation efficiency of the PV array throughout its entire lifecycle.
