High-Efficiency Empowerment · Rock-Solid Reliability — Qierjie Photovoltaic Mounting System: The Perfect Fusion of Quality, Diversity, and Easy Installation I.Ultimate Quality: Defining Industry Standards with Safety and Durability 1. Material and Process Assurance · Utilises high-strength galvanised steel/aluminium alloy materials, passing mechanical tests with tensile strength ≥345MPa and yield strength ≥235MPa, ensuring 30 years of exceptional weather resistance and protection against atmospheric corrosion and salt spray erosion. · Critical connection components undergo hot-dip galvanising (zinc layer ≥80μm) and pass the ISO 9227 salt spray test, eliminating the risk of rust. 2. Extreme Environment Adaptability · Structural design validated through wind tunnel testing and computer simulation, capable of withstanding Typhoon Category 14 (≥45 m/s) and 1.5-metre snow load, unaffected by heavy snow, strong winds, and other harsh weather conditions. · Integrated lightning protection grounding system and cable tray tracks ensure electrical isolation, eliminating the risk of leakage. 3. Full Lifecycle Quality Control · From raw materials to finished products, 10 full inspection procedures are conducted, compliant with national standard GB/T 31985-2015 and international UL2703 certification, with a 25-year structural warranty provided. II. Diverse Scenario Coverage: Customised Mounting Solutions Mounting System Type Application Scenario Core Advantages Roof-mounted distributed mounting system Residential/commercial rooftops Lightweight design (≤12 kg/㎡), compatible with colour-coated steel sheets/tiles/flat roofs, equipped with waterproof clamps 24 Ground-mounted fixed mounting system Agricultural-photovoltaic integration/large-scale ground-mounted power plants Wide span design (5–8 metres), clearance ≥3 metres, ensuring normal agricultural/fishing operations 3 Flexible Tracking Mounting System Complex mountainous terrain/tidal flats Steel cables adapt to terrain, slope adjustment ±30°, reducing land levelling costs 13 Floating System Lakes/reservoirs High buoyancy design + food-grade HDPE floats, UV-resistant, integrated maintenance access 2 III. Minimal Installation: Complete System Deployment in 3 Steps 1.Pre-assembled modular design · Components use snap-fit connections, with 75% of parts pre-assembled in the factory, reducing on-site welding/drilling and improving installation efficiency by 50%45. 2.Smart Adaptive System · Provides a roof scanning modelling tool to automatically generate mounting bracket layout plans; standard-equipped universal clamps compatible with 99% of photovoltaic modules4. 3.Enhanced Construction Convenience · Foundation construction options include spiral ground anchors (no concrete curing required) or precast concrete bases, enabling installation of a kilowatt-scale array within 24 hours.
