Double-beam Alloy Steel Frame Empowers Green and Safe PV — "Safety and Green Technology Seminar" Successfully Concluded!

Guided by the "dual carbon" goals, the PV industry is accelerating into a new phase of high-quality development characterized by "safety + greenness". On June 10th, the "Safety and Green Technology Seminar", hosted by Zhongjian Materials, was successfully held in Shanghai. At the event, the highly anticipated "double-beam alloy steel frame" was unveiled, becoming an innovative solution to address extreme weather conditions and enhance module safety. Representatives from state-owned enterprises, EPC companies, leading module manufacturers, as well as experts and scholars, gathered to discuss the future development path of the PV industry driven by "hard technology".

With the increasing frequency of extreme weather events, the severity of power plant safety incidents is escalating. Amidst the ongoing trends of larger and thinner modules, there is an urgent need for breakthroughs in the mechanical strength of PV systems, and the industry is in dire need of higher safety-level load standards.

Qiu Guohui, Vice President of Jolywood and General Manager of the Application BU, introduced that the "Wind-Resistant Module" featuring a "single-glass + transparent backsheet + double-beam alloy steel frame" design has been successfully applied in 19 provinces across the country, with a total installed capacity of 168 MWp. After enduring multiple rounds of extreme weather conditions, including strong typhoons, hailstorms, and heavy snowfall, only one module suffered external damage, while the rest remained intact, fully demonstrating the high safety and reliability of the "Wind-Resistant Module" and attracting significant attention from power plant investors. Mr. Qiu also pointed out that the dust-prevention design of the double-beam alloy steel frame can enhance the power generation efficiency of the Wind-Resistant Module, further increasing power generation revenue for power plant investors.

At the event, Zhongjian Materials signed strategic cooperation agreements with PowerChina Guiyang Engineering Corporation and PowerChina Sichuan Engineering Corporation, as well as a 500MW steel frame project agreement in Shizuishan, Ningxia, with Saifute New Energy, demonstrating customers' high recognition of Zhongjian's products and technological approach.

Zhang Haichao, Member of the Party Committee and Deputy General Manager of PowerChina Guiyang Engineering Corporation, stated that complex environments such as high altitudes and high wind pressures impose higher safety requirements on structural materials. The technological breakthrough in Zhongjian's double-beam steel frames provides more efficient and reliable structural solutions for the corporation. This strategic cooperation will usher in a new chapter of complementary advantages and synergistic development between the two parties.

At the end of the seminar, Lin Jianwei, the founder of Jolywood Group, delivered a speech. He noted that although the PV industry is in a phase of rapid development, it is experiencing anxiety due to cut-throat competition, with intensified cost-reduction and capacity competition. However, the core of future industry competition will no longer be mere scale expansion but rather a return to product quality, technological innovation, and value creation, ushering in the era of "tough competition."

Taking Zhongjian's steel frames as an example, he recounted the seven-year innovation journey spanning three generations: from project initiation in 2018 to achieving hundred-megawatt-scale applications in 2024, and plans to advance to gigawatt-scale promotion in 2025. Lin Jianwei emphasized that the core innovation of Zhongjian's steel frames lies in the "double-beam" structure. By pioneering the "double-beam" structural design and process optimization, they have successfully addressed pain points such as the easy deformation of aluminum frames, combining high safety with cost advantages. It is expected that within five years, this technology will become a mainstream solution, significantly enhancing module quality and reliability.

He called on the industry to build consensus and, supported by professionalism, technology, and ecological collaboration, jointly construct a safer, greener, and higher-quality PV ecosystem.
