NAICS 332311 – Prefabricated Metal Building and Component Manufacturing covers the design, fabrication, and assembly of standardized metal building systems and structural components intended for rapid on-site installation. These include pre-engineered metal buildings (PEMBs), roof and wall panels, framing systems, doors, windows, and associated hardware engineered to meet military, industrial, and federal facility specifications. Products in this sector are widely used in defense infrastructure, logistics hubs, storage facilities, maintenance hangars, and modular support structures, offering cost-effective, durable, and code-compliant solutions for rapid deployment and scalability. This NAICS plays a critical role in the federal government’s capital improvement and contingency construction programs, particularly where speed, resilience, and standardization are paramount. Top contractors in this sector include PVPII - FNSS ACQUISITION, INC, ROCKWELL AMERICAN SERVICES, LTD., ONEIDA BUSINESS ENTERPRISES, INC., H & S COMMERCIAL AND INDUSTRIAL SUPPLIES AND SERVICES LLC, PERFECTED SOLUTIONS LLC, ENFIELD ENTERPRISES LLC, BPM SERVICES INC, and BHPE LLC. The competitive landscape is dominated by small businesses and specialized manufacturers with expertise in military-grade fabrication, ANSI/AISC compliance, and just-in-time delivery systems. Many firms hold small business set-aside certifications, enabling them to compete effectively for targeted procurements. The Department of Defense is the primary buyer, with significant demand driven by base modernization, overseas contingency operations, and readiness infrastructure projects. The Department of Commerce and W074 Endist Wilmington also award contracts for facility upgrades and logistics support structures, often requiring compliance with DoD 4150.2 standards and seismic or corrosion-resistant design criteria. The market is characterized by high opportunity density in modular construction and rapid-response procurement vehicles, with recurring demand for standardized, repeatable building systems. Contractors with certified manufacturing capabilities, ISO 9001 quality systems, and experience in federal supply chain protocols are best positioned to compete. Trends indicate growing emphasis on sustainability, energy-efficient cladding, and integration with smart building systems.

Small Business Size Standard

The SBA threshold that decides who can bid NAICS 332311 work as a small business.

750 employees
Applies to the whole industry code

The SBA cap for this NAICS (13 CFR 121.201). A business at or under it can self-certify as small for work in this code, which is what makes it eligible for a small-business set-aside. The cap is set per NAICS, so the same company can be small in one code and not in another.

13 CFR 121.201, effective January 1, 2026. The SBA revises the table roughly once a year.

Bidder counts reported on past federal awards in this NAICS (USAspending). An open opportunity has no bidders yet, so this is the historical norm for similar work, not a fact about this solicitation. Not all awards report bidder counts, and fewer bidders often means incumbent-held work rather than an easier win. Federal reporting of bidder counts fell from ~96% of awards (FY2016) to ~30% (FY2018 onward); the chart shows shares of reported awards, and washed-out stretches mark years with fewer than 30 of them.
