Building metal manufacturers and suppliers are facing a constantly evolving supply landscape

Currently, as a core component of curtain wall and door/window systems, the supply chain of construction metals is undergoing profound adjustments. Affected by macroeconomic and policy environments, manufacturers, processors, and suppliers of construction metals face new challenges in material supply, procurement strategies, and product development. The industry is adapting to the dynamic market landscape through diversified adjustments.

In 2025, the U.S. will reinstate and significantly raise the steel and aluminum tariffs under Section 232 to 50%, while Chinese-related products will face additional tariffs under Section 301. Other categories will also encounter corresponding trade restrictions. The high tariffs will intensify fluctuations in raw material costs and increase delivery uncertainties, prompting customers to lock in prices early and frequently update quotations. On one hand, companies will optimize their import structures and diversify their product portfolios; on the other, they will enhance collaborative planning with customers. However, tariffs also have negative effects, potentially forcing aluminum-exporting countries to shift to other markets. Moreover, the ad valorem taxation model may drive up the costs of high-value-added products when demand recovers.

Meanwhile, the Buy American Act and its upgraded version, the Build America Buy America (BABA) policy, continue to tighten regulations, requiring that aluminum ingots used in federally funded infrastructure projects must be smelted and produced domestically. The compliance thresholds for government-related projects have significantly increased. Companies need to accurately interpret the differences in provisions, but some alloy categories still face challenges in achieving fully domestic supply.

The long-term reliance on Canadian aluminum sources is shifting. The U.S. domestic primary aluminum production capacity has significantly declined, with over 60% of imports coming from Canada. Driven by Section 232 tariffs, Century Aluminum will restart idle facilities and build the first primary aluminum smelter in the U.S. in 45 years, while Emirates Global Aluminium also plans to establish a plant in the U.S. The industry is simultaneously calling for improved recycling systems to leverage aluminum's recyclability and enhance supply chain autonomy and control.

Additionally, performance upgrades, labor shortages, and sustainable development collectively drive product innovation. High thermal performance and hurricane resistance have become standard requirements, while prefabrication and modular construction accelerate adoption in cities with high labor costs. The demand for green and low-carbon solutions continues to strengthen, with low-carbon materials, recycled components, and Environmental Product Declarations (EPDs) emerging as mainstream market demands. Supporting materials like coatings are also evolving toward lower VOC and reduced carbon waste, leading the industry toward a transformation focused on high performance, transparency, and sustainability.
