North America

The North America structural steel market size surpassed USD 24.91 billion in 2025 and is predicted to reach around USD 39.81 billion by 2035, registering a CAGR of 4.8% from 2026 to 2035. The market is mainly fueled by government investments in renewing public infrastructure, a rise in reshoring industrial jobs, and the expansion of manufacturing facilities. There is also a growing commercial need for wide-span areas such as data centers, along with a significant shift towards sustainable and recyclable green building materials.

North America Structural Steel Market Statical Scope

The market supports the region's extensive non-residential construction, large infrastructure projects, and advanced industrial manufacturing. It offers the essential load-bearing framework necessary for economic growth, urban development, and energy transition initiatives. Federal and state funding helps in modernizing old bridges, highways, transit systems, and public utility networks. The rapid growth of large data centers, logistics centers, and manufacturing plants requires strong structural components like beams and columns.

Steel's excellent strength-to-weight ratio and its recyclability meet green building standards and corporate sustainability objectives. Innovations in computer-aided manufacturing, laser cutting, and robotic welding enhance the speed, safety, and cost-effectiveness of steel fabrication.

North America Structural Steel Market, By Product, 2025 (%)

• High Sectional Steel - High sectional steel, with a share of 38.00% in 2025, often referred to as heavy or high-performance structural steel sections like wide-flange beams, heavy columns, and specialized shapes, accounts for the largest revenue share in North America's structural steel market. It offers the essential load-bearing capacity and structural integrity needed for large commercial, industrial, and public infrastructure projects.
• Light Sectional Steel - The light sectional steel segment, with a share of 24.00% in 2025, is crucial in the North American structural steel market, as it promotes cost-effective, sustainable, and rapid construction. This segment supports lightweight framing, modular building, and adaptable architectural designs, serving as a replacement for traditional wood and heavy concrete options.
• Rebar - The rebar segment, with a share of 38.00% in 2025, which includes reinforcing bars, is critical to the North American structural steel market as it delivers the necessary tensile strength and load-bearing capacity to reinforce concrete in civil infrastructure, bridges, and high-rise buildings.

North America Structural Steel Market, By Application, 2025 (%)

• Residential - The residential segment, with a share of 31.00% in 2025, is vital in the North American structural steel market, driven by urbanization and high land prices. This shift leads to a preference for mid-rise and high-rise multi-family housing, where steel replaces traditional wood framing for improved strength, speed, and open-space architectural designs.
• Non-Residential - The non-residential segment, with a share of 69.00% in 2025, is the largest and most profitable segment in the North American structural steel market. It fuels ongoing demand due to substantial investments in large commercial complexes, industrial manufacturing plants, public infrastructure, data centers, and institutional buildings that require robust load-bearing frameworks.
