VI. Market Prospects
PV Installations Continue to Rise: In 2025, China's newly installed PV capacity exceeded 250GW, driving a significant increase in demand for PV bracket cold bending equipment. The demand for solar brackets is experiencing explosive growth.
The Cold Bending Equipment Market is Growing Rapidly: In 2025, the market size of my country's cold bending equipment exceeded 28 billion yuan, with an average annual compound growth rate of around 12%. PV brackets, light steel keels, and metal sheet roll forming equipment are the fastest-growing sub-sectors. The pain points of traditional cold bending equipment—slow changeover, poor precision, and low efficiency—are becoming obstacles to enterprise expansion. Equipment suppliers not only need to provide standardized CNC roll forming machines but also need the ability to develop fully automated roll forming production lines for specific application scenarios (such as PV, warehousing, and construction).
The Trend of Steel Frames Replacing Aluminum Frames is Obvious: Using galvanized aluminum-magnesium alloys to replace traditional aluminum frames in steel frame products reduces costs by approximately 40% while doubling the strength of traditional aluminum frames. Leading companies in the industry, in conjunction with the China Photovoltaic Industry Association and the China Iron and Steel Association, have spearheaded the development of group standards for "Galvanized Aluminum-Magnesium Steel Frames for Photovoltaic Modules" and "Galvanized Aluminum-Magnesium Closed-Type Cold-Formed Steel Frames for Photovoltaic Modules." As steel frame technology matures and standards improve, the penetration rate of steel frames in photovoltaic modules will continue to increase.
Intelligent and Flexible Upgrades: Photovoltaic bracket cold-forming production lines equipped with 9-axis servo punching machines, featuring "high-precision punching + fully automatic form changeover," have become the preferred equipment for photovoltaic companies to reduce costs and increase efficiency. By introducing laser online measurement technology, key parameters of the profiles can be monitored in real time, and the forming molds can be automatically adjusted to ensure product accuracy reaches ±0.2mm.
