CLAMSHELL STRUCTURES, INC

Clamshell Structures, Inc. specializes in the design, manufacture, and supply of precision metal and polymer components for modular, deployable shelter systems used in military and federal infrastructure applications. The company’s core expertise lies in fabricated structural metal components, prefabricated metal building systems, and engineered plastic piping solutions tailored for high-deployment environments. Their technical proficiency includes producing anti-rotator plates, wire rope assemblies, replacement panels, and structural fittings that meet stringent military specifications for durability, rapid assembly, and environmental resilience. A distinguishing capability is their deep familiarity with Clamshell-style temporary shelter architectures, enabling them to deliver mission-critical replacement parts and subsystems with exacting dimensional and material compliance, often under tight operational timelines. The company maintains a consistent and primary relationship with the Department of Defense, supplying components for expeditionary and fixed-site shelter systems across multiple U.S. and overseas installations, including Hill Air Force Base and Ali Al Salem. Their work supports logistics, housing, and operational readiness missions through direct part replacement and system sustainment. The General Services Administration engagement reflects their inclusion in federal supply channels, indicating formalized procurement pathways for standardized government inventory. Clamshell Structures primarily operates within NAICS 332311 (prefabricated metal building manufacturing), 332312 (fabricated structural metal manufacturing), and 326122 (plastics pipe and fitting manufacturing), positioning them as a niche supplier in defense infrastructure support. Their market focus is on modular, field-deployable systems requiring precision metal fabrication and polymer-based fluid or structural components, serving the tactical shelter and temporary infrastructure vertical. As a small business structured as a 2L entity based in Ventura, California, Clamshell Structures operates without federal certifications but maintains a focused, defense-oriented supply chain presence. Their geographic location supports efficient logistics to West Coast military hubs and expeditionary deployment points, reinforcing their role as a specialized, responsive vendor in the federal tactical infrastructure ecosystem.
