Industry Summary
The 13,179 metal manufacturers in the US produce structural, ornamental, and architectural metal products, primarily for use in the construction industry. Major product categories include sheet metal work; fabricated structural metal products; ornamental and architectural products; plate work; windows and doors; and prefabricated building and component products. Sheet metal work includes air conditioning ducts and stove pipe; electronic enclosures; roofing and roof drainage equipment; flooring and siding; and culverts, flumes, and irrigation pipe. Fabricated structural metal products include bar joists, concrete reinforcements, and structural metal for bridges.
Seasonal Sales
Sales are seasonal and driven by construction activity, which typically peaks during warmer weather.
Capital-Intensive Operations
Historically, architectural and structural metals manufacturing has been a capital-intensive industry and is becoming more so as the pace of technological change accelerates.
Recent Developments
Dec 18, 2025 - Procuring Low-Carbon Steel
- Producers of architectural and structural metals looking to reduce their carbon footprint have a new resource to help procure low embodied carbon structural steel, Modern Steel Construction reports. The American Institute of Steel Construction’s (AISC) newly-released Specification Strategies for Embodied Carbon Reduction is poised to influence how architectural and structural steel manufacturers compete and operate. The guide encourages firms to require Environmental Product Declarations (EPDs), fabricator sustainability documentation, domestic sourcing, and steel produced by Electric Arc Furnaces (EAF), all of which shift market expectations toward lower‑carbon products. As scrutiny of sustainability practices increases, manufacturers that invest in cleaner production and traceable sustainability practices will likely have a competitive advantage. The new guide is a collaboration between AISC's Sustainability Committee, the Resources Subgroup of the SEI Sustainability Committee, the Specification Working Group of the NCSEA National Sustainable Design Committee, and a consulting architect specializing in specification writing.
- Architectural and structural metals manufacturers are facing increasing cost and engineering pressures due to more stringent local‐ and state‐building codes, Metal Construction News reports. Key drivers include snow loads, wind loads, fire ratings, and aesthetic/finish requirements, all of which frequently necessitate heavier gauges, stronger anchoring systems, additional materials (insulation, fire‐resistant barriers, framing upgrades) and more rigorous engineering. For manufacturers of architectural and structural metals this means upfront costs escalate (more steel, more testing), longer lead times, and the need to supply more complex, code‐compliant systems rather than simple commodity panels. At the same time, the increased stringency is an opportunity for firms that develop pre‐engineered, code‑ready metal systems or high‐performance finishes to win more business. To succeed in the increasingly regulation‑heavy metal building market, manufacturers must prioritize engineering expertise, robust supply chains, and product innovation.
- In September, domestic steel prices fell to their lowest levels since February, giving up earlier tariff-driven gains, OilPrice.com reports. Weak demand from the construction sector, short mill lead times, and volatile durable goods orders are putting downward pressure on prices, including for hot-rolled steel coil, which in early September saw its lowest price since February. The Raw Steels Monthly Metals Index (MMI), which tracks steel prices, fell nearly 1% from August to September. In the first quarter, prices jumped $241 per short ton following tariff announcements by the Trump administration. However, since peaking in March, prices have fallen $109 to $818 per short ton. Prices for cold-rolled coil and hot-dipped galvanized steel are also trending downward. While tariffs have provided support for domestic steel prices, falling demand from the construction and manufacturing sectors is dragging down steel prices.
- Producer prices for architectural and structural metals manufacturers rose 7.6% in September compared to a year ago – a record high for the industry – after rising just 0.5% in the previous September-versus-September annual comparison, according to the latest US Bureau of Labor Statistics data. Import tariffs on aluminum and steel, along with a more recent tariff on raw copper, are raising costs for manufacturers, prompting them to hike prices. Employment by the industry is also at a record-high level, up 3.3% year over year in August, while average wages at architectural and structural metals manufacturers rose 6.5% over the same period to a new high of $27.46 per hour, BLS data show.

Industry Structure
Industry size & Structure
The average architectural and structural metals manufacturer operates out of a single location, employs about 31 workers, and generates $11.4 million annually.
- The architectural and structural metals manufacturing industry consists of about 13,179 companies, employs 413,900 workers, and generates about $150.8 billion annually.
- The industry is highly fragmented; the top 50 firms account for only 29% of industry sales.
- Some large companies are vertically integrated and own and operate raw steel manufacturing facilities, such as mini-mills.
- Large companies include Valmont Industries, Cornerstone Building Brands, OmniMax International (formerly Euramax International), Quanex Building Products, and Gibraltar Industries.
- Commercial construction accounts for the majority of industry sales.
- Structural steel is the most commonly used framing material in the US, and accounts for over half of framing used in non-residential and multi-story (more than four stories) residential construction, according to the American Institute of Steel Construction (AISC).
