FOURINOX, INC.

FOURINOX, INC. specializes in the precision manufacturing of high-integrity metal components for defense and industrial applications, with demonstrated expertise in fabricating demineralizer tanks from 300-series stainless steel, including 304 CRES. Their technical capabilities center on corrosion-resistant alloy fabrication, precision welding, and adherence to stringent metallurgical specifications required for critical fluid-handling systems in harsh operational environments. The company’s focus on material integrity, dimensional accuracy, and compliance with military-grade material standards positions them as a niche supplier of mission-critical components for demanding government systems. Their production processes likely involve CNC machining, forming, and surface finishing techniques tailored to meet ASME, ASTM, or MIL-SPEC requirements for stainless steel pressure vessels and process equipment. The contractor has delivered specialized machinery components to the Department of Defense, indicating direct engagement with defense logistics and maintenance programs requiring durable, non-corrosive fluid treatment infrastructure. Their work supports naval, environmental, or life-support systems where water purity and material longevity are paramount. This suggests a pattern of responsive, low-volume, high-precision contracting aligned with niche defense procurement needs rather than broad-scale production. FOURINOX operates primarily under NAICS 333310, which encompasses the manufacturing of commercial and service industry machinery—specifically, custom-engineered equipment for water treatment, industrial processing, and environmental control systems. Their market positioning is that of a specialized fabricator serving defense and institutional clients requiring certified, corrosion-resistant components, rather than mass-produced hardware. As a Service-Disabled Veteran-Owned Business headquartered in Green Bay, Wisconsin, FOURINOX leverages its veteran-owned status to meet federal small business set-aside requirements. The company’s 2L entity structure indicates a small, focused operation with agile production capabilities, well-suited for contract-specific, low-volume manufacturing missions within the defense supply chain.
