Focusing on the Chinese market, the architectural stainless steel market size is expected to reach 130.58 billion RMB in 2025, demonstrating strong market vitality. A brief analysis from the perspectives of product trends, market size, and competitive landscape follows:

I. Product Trends: Parallel Development of High-End and Functionalization

• Material Upgrades: Rise of Duplex Steel and Nickel-Saving Stainless Steels
  In 2025, the product structure of architectural stainless steel is accelerating its transition towards high performance. The application share of duplex stainless steels (e.g., S32205) in scenarios like modular construction and cross-sea bridges is expected to exceed 25%, with their high strength (yield strength ≥450MPa) and corrosion resistance (Pitting Resistance Equivalent Number PREN≥32) offering significant advantages over traditional 304 stainless steel. Nickel-saving stainless steels (e.g., QN series), due to cost reductions of 18%-20%, are seeing their penetration rate in commercial building structural components increase from 12% in 2023 to 18% in 2025, effectively mitigating the impact of nickel price fluctuations on the industry chain. Furthermore, copper-containing antibacterial stainless steel (Cu≥3.8%) has achieved a penetration rate of 34% in sanitary ware systems for public buildings like hospitals and schools, becoming a new growth point in niche markets.

• Process Innovation: Integration of Lightweighting and Intelligence
  Laser-welded stainless steel composite panel technology reduces material costs for curtain wall systems by 28%, driving its application proportion in super high-rise buildings from 22% in 2023 to 35% in 2025. The maturity index of 3D printed stainless steel components increased from 62 in 2023 to 89, with the adoption rate of special-shaped structural components in infrastructure projects reaching 35%. For instance, the Ganzhou "Stainless Steel Banyan Tree" landmark project achieved millimeter-level precision installation of 460 tons of special-shaped stainless steel structure through parametric modeling and BIM collaborative technology. Breakthroughs in surface treatment technologies (e.g., antique copper, wood grain nickel finishes) have increased the application share of decorative stainless steel sheets in commercial complexes to 45%, an 8 percentage point increase from 2023.

• Green Attributes: Strengthening Low-Carbon and Recyclability
  The application rate of hydrogen-based direct reduced iron (DRI) technology in medium and heavy plate production surpassed 10%, reducing unit energy consumption by 18%-20% compared to traditional processes, driving the market share of low-carbon stainless steel products from 25% in 2023 to 35% in 2025. The target for scrap stainless steel recycling and reuse rate is set to reach 95% by 2030, with the proportion of recycled stainless steel used in construction expected to reach 35% in 2025. Due to stricter green building certification requirements, the proportion of recycled stainless steel in the EU market reaches 52%.

II. Market Size and Growth: Structural Divergence and Regional Expansion

• Global Market: Steady Growth and Regional Gradients
  The global architectural stainless steel market size from 2025 to 2030 is projected to expand at a compound annual growth rate (CAGR) of 6.8%, exceeding $85 billion by 2030. The Asia-Pacific region leads the growth, with demand from China, India, and Southeast Asian emerging economies exceeding 18 million tons in 2025, accounting for 42% of the global total. In China, the penetration rate of stainless steel in super high-rise building curtain walls and prefabricated steel structure residences is expected to increase from 18% in 2023 to 29% by 2030. Driven by green building regulations in European and American markets, the demand for duplex stainless steel shows an average annual growth of 9.3%, with the proportion of recycled stainless steel reaching 52%.

• Chinese Market: High-End Trends and Policy Drivers
  China's architectural stainless steel market size is expected to reach 320 billion RMB in 2025, with the decoration sector accounting for 55%, high-end residences 30%, and commercial complexes 15%. Demand in the public building sector is growing the fastest, as the "Carbon Peaking Implementation Plan for Urban and Rural Construction" requires the use proportion of stainless steel in new public buildings to be no less than 35% by 2025, directly driving an annual incremental demand of 400,000 tons. The penetration rate of prefabricated buildings is expected to increase from 32% in 2023 to 55% by 2030, driving an average annual increase of 12% in stainless steel consumption for prefabricated component connectors.

• Regional Patterns: Core Economic Circles and Emerging Markets
  The Yangtze River Delta, Pearl River Delta, and Bohai Rim economic circles account for 68% of China's architectural stainless steel market share. Among them, East China's consumption reaches 4.2 million tons, accounting for 37% of the national total, focusing on high-end curtain walls, prefabricated buildings, etc. The central and western markets are catching up, with the Chengdu-Chongqing dual-city economic circle showing a infrastructure investment CAGR of 9.8%. Stainless steel demand there is expected to increase from 950,000 tons to 2.1 million tons in 2025, but products are mainly mid-to-low end 201/430 series (72% share). Benefiting from the RCEP trade agreement, the Southeast Asian market has a stainless steel demand growth rate of 9.2%, preferring cost-effective 410S ferritic stainless steel (63% of China's exports).

III. Competitive Landscape: Consolidation at the Top and Breakthrough through Differentiation

• Leading Enterprises: Vertical Integration and Technological Barriers
  Leading Chinese enterprises like Tisco and Baowu plan to build five million-ton level stainless steel production bases dedicated to construction by 2026. Tisco's developed QN series stainless steel holds an 18% share in the commercial building market. POSCO focuses on smart building solutions, developing building stainless steel facade systems integrated with photovoltaic power generation, holding a 22% market share in South Korea and Southeast Asia. Tsingshan Holding Group, through its nickel pig iron production capacity layout in Indonesia, reduces raw material costs, and its 304 stainless steel holds a 15% market share domestically.

• SMEs: Niche Markets and Customized Services
  Small and medium-sized enterprises (SMEs) have formed complete product matrices in areas like electromagnetic shielding stainless steel plates for data center racks and ultra-thin precision strips (0.02mm) for smart building sensors, maintaining profit margins above 25%. For example, Qinbiao Stainless Steel improved shipping efficiency by 30% through intelligent warehousing systems, achieving a 50% year-on-year sales growth in the stainless steel shelving sector.

• Regional Strategies: Evading Trade Barriers and Localized Production
  Leading enterprises are establishing regional processing centers in Southeast Asia. For instance, Baowu is building a 500,000-ton annual stainless steel deep-processing base in Malaysia to circumvent the pressure of a $120 per ton cost increase potentially brought by the EU's Carbon Border Adjustment Mechanism (CBAM). Tisco has deployed vacuum coating energy-saving stainless steel production lines in Central and Eastern Europe to meet the upgrading needs of local building energy efficiency regulations, achieving a 35% year-on-year increase in export volume in 2024.
