Over the past decade, China's metal profile industry has undergone a fundamental transformation from 'scale expansion' to 'quality and efficiency leap' through technological innovation. The core path focuses on three dimensions: intelligent manufacturing, green low-carbon, and material upgrading. In terms of intelligent manufacturing, represented by leading enterprises such as Baowu and Chinalco, AI quality inspection, 3D digital twins, and industrial internet platforms have been comprehensively deployed. The defect detection rate of cold-rolled silicon steel exceeds 95%, the research and development cycle is shortened by 35%, and unmanned cranes and intelligent scrap grading systems have achieved normalized operation in 'black light factories'. In terms of green manufacturing, the industry is accelerating the promotion of energy-saving extrusion, waste heat recovery, and recycling technologies. By 2025, the output of metal profiles is expected to reach 180 million tons, with a decrease of over 20% in unit energy consumption compared to 2015. In terms of material innovation, high-strength aluminum alloys, lightweight profiles, and integrated die-casting structural components have become core supplies for new energy vehicles and rail transit. Enterprises such as Gansu Hongda have completed the strategic transition from building profiles to industrial aluminum profiles, with product added value increased by more than three times. The national 'Work Plan for Digital Transformation of the Raw Material Industry' has established a standard system, promoting 'equipment networking rate exceeding 90% and numerical control rate exceeding 85%' as the new threshold for the industry. China's metal profile industry is transforming from a 'global supplier' to a 'technology definer'.
