Conclusion
In summary, regarding PV module frame manufacturers: Yongzhen operates five major production bases (Yingkou, Liaoning; Changzhou, Jiangsu; Chuzhou and Wuhu, Anhui; and Vietnam) with a total annual production capacity of 690,000 tons of PV aluminum frames; its products are lightweight, highly stable, weather-resistant, and corrosion-resistant (Yongzhen). PV frames protect module edges, enhance sealing and overall mechanical strength, facilitate transport and installation, and offer high recyclability (Yongzhen products). Yongzhen is a leading domestic manufacturer of high-quality aluminum alloy PV structural components, with a product line covering frames, mounting systems, and precision parts (Yongzhen official website). According to QYResearch, PV aluminum frames protect solar panel edges and provide mechanical strength, rigidity, and mounting support; they are made from high-strength, corrosion-resistant aluminum alloy extrusions using an anodizing process (QYResearch).
Shengao Aluminum produces PV panel frames and lithium battery casings (Shengao). Overseas B2B strategy: Thoroughly vet materials, certifications, manufacturing processes, and samples—and avoid the pitfall of focusing solely on unit price without verifying the aluminum alloy grade and anodizing thickness (which can lead to frame corrosion and breakage)—to successfully establish a solid partnership with PV module frame manufacturers.
