Key metrics for the other concrete product manufacturing industry.
Industry Definition & Overview
Other Concrete Product Manufacturing (NAICS 327390) encompasses establishments primarily engaged in manufacturing concrete products other than block, brick, and pipe. This broad classification includes precast concrete panels, prestressed concrete beams and girders, concrete burial vaults and boxes, decorative concrete products, concrete furniture, and various specialty precast items.
These manufacturers serve construction, infrastructure, funeral services, and landscaping markets. Precast structural and architectural concrete represents the largest product segment, with plants producing wall panels, floor slabs, double tees, columns, and stair units for commercial and residential buildings. According to the U.S. Census Bureau[5], this code functions as a residual category capturing all concrete products not specifically assigned to pipe (327332), block and brick (327331), or ready-mix (327320).
Production methods vary widely across the product range. Structural precast operations require large indoor plants with overhead cranes, prestressing beds, and climate-controlled curing areas. Smaller specialty producers may operate open-air yards making garden products, pavers, or septic tanks. The industry includes both custom fabricators producing to architectural specifications and commodity producers running standardized product lines. Quality control programs such as PCI certification govern structural precast operations, while burial vault producers follow different industry standards for waterproofing and load resistance. Product weight and bulk limit economical shipping distances for most items.

Key Insight: The SBA[8] classifies Other Concrete Product Manufacturing under NAICS 327390 with a size standard of 500 employees. This threshold reflects the mix of small custom fabricators and larger standardized producers in the industry. Many precast concrete plants operate with fewer than 100 workers, making most firms eligible for SBA lending programs[9] and federal small business contracting preferences. Capital-intensive equipment needs for cranes, forms, and curing systems make SBA 504 loans particularly relevant for plant investment. The SBA 7(a) loan program[10] also provides general-purpose financing for working capital, equipment, and business acquisitions.

Frequently Asked Questions
Common questions about this industry.
What types of businesses fall under NAICS 327390?
NAICS 327390 includes manufacturers of precast concrete panels, prestressed beams, burial vaults, concrete pavers, septic tanks, railroad ties, and decorative concrete products. These range from large structural precast plants with overhead cranes and prestressing beds to smaller specialty operations producing garden products or utility vaults. According to the U.S. Census Bureau[5], this code captures all concrete products not classified under pipe, block/brick, or ready-mix codes.
How is NAICS 327390 organized in the classification hierarchy?
This code falls within Industry Group 3273 (Cement and Concrete Product Manufacturing), Subsector 327 (Nonmetallic Mineral Product Manufacturing), and Sector 31-33 (Manufacturing). It serves as the residual category under 3273, capturing concrete products that do not fit the more specific codes for cement (327310), ready-mix (327320), or concrete pipe, brick, and block (32733x).
What is the SBA size standard for NAICS 327390?
The SBA[8] sets the size standard at 500 employees for Other Concrete Product Manufacturing. Businesses with fewer than 500 employees qualify as small businesses for federal contracting set-asides and SBA-guaranteed financing programs.
Which NAICS codes are most closely related to 327390?
The closest codes are 327331 (concrete block and brick) and 327332 (concrete pipe), which share raw materials and production techniques but cover specific product types. Code 327320 (ready-mix concrete) is a major material supplier. Per the Census Bureau NAICS manual[11], the distinction between 327390 and its sibling codes rests on the specific product form rather than the manufacturing process.
What industries interact most with other concrete product manufacturers?
Commercial building construction (236220) and highway construction (237310) drive the largest share of demand for precast structural and infrastructure products. Poured concrete contractors (238110) install precast elements on job sites. Sand and gravel mining (212321) supplies aggregates, and cement manufacturing (327310) provides the binding agent for all concrete products.
What activities does NAICS 327390 specifically include?
Activities include manufacturing precast concrete wall panels, prestressed beams, double tees, floor slabs, stair units, burial vaults, septic tanks, pavers, retaining wall blocks, sound barriers, railroad ties, parking garage components, and decorative garden products. Per NAICS reference sources, the common thread is concrete product manufacturing that does not fit the pipe, block, brick, or ready-mix categories.
Are other concrete product manufacturers eligible for SBA loans?
Yes. Manufacturers under NAICS 327390 with fewer than 500 employees can access SBA loan programs[9] including 7(a) loans for equipment and working capital, 504 loans for real estate and heavy machinery, and disaster loans when applicable. These programs help precast plants finance forms, cranes, batch plants, and facility expansions.
Where are other concrete product manufacturers concentrated geographically?
Precast concrete plants cluster near major construction markets because finished products are heavy and costly to ship long distances. States with strong construction activity such as Texas, Florida, California, Pennsylvania, and Ohio support higher concentrations of producers. Burial vault manufacturers distribute more broadly but still tend to locate within regional service areas to manage freight costs.
