The event also served as a centralized showcase for the industry's latest technological achievements and exemplary applications.

I. Policy-Driven: The Industry Enters a New Phase of High-Quality Development

During the opening ceremony, a representative from the Ministry of Housing and Urban-Rural Development delivered an address highlighting that steel structure construction—as a quintessential example of green building—possesses distinct advantages such as a high degree of industrialization, superior seismic resistance, and recyclability. It serves as a crucial lever for driving the transformation and upgrading of the construction industry and for achieving the national goals of peaking carbon emissions and attaining carbon neutrality. In recent years, the government has successively issued a series of policies—including the *Opinions on Promoting Green Development in Urban and Rural Construction* and the *14th Five-Year Plan for the Development of the Construction Industry*—explicitly calling for the vigorous development of prefabricated steel structure buildings. Notably, the adoption rate of steel structures is steadily rising across various sectors, particularly in schools, hospitals, affordable housing projects, and urban renewal initiatives.

In his keynote report, Luo Tiejun, Vice President of the China Iron and Steel Association, stated that in 2023, my country's steel structure processing volume surpassed 120 million tons for the first time—marking an 8.5% year-on-year increase and maintaining a trajectory of rapid growth for five consecutive years. Driven by the research, development, and application of high-performance steels—including weather-resistant and high-strength varieties—the scope of steel structure application is expanding beyond traditional industrial plants and super-high-rise buildings to encompass broader fields such as bridges, residential housing, offshore engineering, and urban infrastructure.

II. Focusing on "New Quality Productive Forces": Intelligent Manufacturing and Digitalization Take Center Stage

The forum featured a series of parallel sessions, among which the specialized track titled "Intelligent Manufacturing and Digital Transformation of Steel Structures" proved to be immensely popular. Numerous industry experts pointed out that traditional steel structure production is currently undergoing a profound transformation—shifting from manual welding and cutting operations to collaborative systems powered by clusters of robotic automation. Industry leaders such as Hangxiao Steel Structure, Jinggong Steel Structure, and Honglu Steel Structure showcased their latest smart factory solutions. From BIM (Building Information Modeling)-based platforms for full lifecycle management to "dark factories" featuring unmanned cutting, automated welding, and intelligent warehousing, digital technologies are fundamentally reshaping the production logic of the steel structure industry. Attendees visited a demonstration line for a "Future Steel Structure Factory" located in the Yangtze River Delta region; powered by a dedicated 5G network, this facility directly translates design data into machine instructions, boosting production efficiency by 40% and reducing energy consumption by 15%, thereby realizing the industrialized vision of "building houses just like manufacturing cars."

III. Technological Innovation Solves Pain Points; High-Performance Materials Drive Low-Carbon Transition

In the technological innovation exhibition zone, various high-performance steel materials took center stage. Baowu Steel Group showcased its "high-performance weathering steel," which resists atmospheric corrosion without the need for painting—significantly reducing lifecycle maintenance costs—and has already been deployed in several landmark bridges and outdoor structures. Furthermore, addressing the challenges associated with integrating the "three panels" (floor slabs, wall panels, and roof panels) in residential construction, numerous companies presented ALC (Autoclaved Lightweight Concrete) panels—highly compatible with steel structure systems—alongside novel composite enclosure systems and integrated interior finishing solutions. These innovations effectively resolve common consumer pain points associated with traditional steel-structure housing, such as issues regarding sound insulation, water leakage, and overall comfort.

In his keynote speech titled "Frontier Technologies in Steel-Concrete Composite Structures," Nie Jianguo—a professor in the Department of Civil Engineering at Tsinghua University and an Academician of the Chinese Academy of Engineering—emphasized that the future development of steel structures must not solely pursue increased steel consumption; rather, it should prioritize the optimization of structural systems and the full utilization of material performance. Through composite structure technologies, it is possible to achieve smaller and lighter structural cross-sections, thereby enhancing structural safety redundancy while simultaneously further reducing embodied carbon emissions.

IV. Going Global and Integration: Exploring New Blue Oceans for the Industry

As the "Belt and Road Initiative" continues to advance, China's steel structure enterprises are accelerating their "going global" strategies. During the roundtable discussion on "Internationalization Strategies for Steel Structure Enterprises," representatives from companies such as China Construction Steel Structure (CCSS) and the China Metallurgical Construction Research Institute (MCC CERI) shared their experiences in undertaking major landmark projects in regions including Saudi Arabia's futuristic NEOM city, Southeast Asia, and the Middle East. Academician Yue Qingrui, President of the China Association of Steel Construction, pointed out that China’s steel structure manufacturing capabilities and construction technologies have already reached an advanced international level. The next step, he noted, should focus on promoting the "going global" of Chinese standards, strengthening alignment with internationally accepted building codes, and enhancing China's influence within the global industrial chain.

Meanwhile, the trend of cross-sectoral integration is becoming increasingly evident. The combination of Building-Integrated Photovoltaics (BIPV) and steel structures emerged as a major highlight of the exhibition. Numerous companies showcased integrated products that seamlessly embed photovoltaic modules directly into steel structure roofs and walls. This innovation transforms buildings from mere "energy consumers" into "energy producers," offering a viable pathway toward carbon-neutral operations for industrial facilities, commercial complexes, and public buildings.

V. Looking Ahead: Building a Green, Safe, and Intelligent Steel Structure Ecosystem

During the closing ceremony, the conference released the *Shanghai Initiative for the High-Quality Development of the Steel Structure Industry*. This initiative calls upon the entire industry to: First, remain driven by innovation and overcome bottlenecks in key core technologies; second, deepen green manufacturing practices and establish a robust accounting system for the carbon footprint of steel structure products; third, strengthen talent pipeline development and cultivate a new generation of "modern craftsmen" adapted to the era of intelligent construction; and fourth, refine the standards system to facilitate the large-scale application of steel structures within the residential housing market.

According to industry forecasts, by 2030, my country's annual steel consumption for steel structure applications is expected to exceed 200 million tons, with its penetration rate in new construction projects rising from the current level of approximately 10% to over 30%. The steel structure industry is currently undergoing a critical transition—a leap from "rapid growth" to "high-quality development." As intelligent construction technologies provide deeper empowerment and green, low-carbon concepts are fully implemented, steel structures will serve as a steadfast pillar in the creation of safer, more livable, and sustainable urban environments.
