At Composites USA, Inc., we specialize in the design and fabrication of high-performance fiberglass products that meet the rigorous demands of industrial, commercial, and municipal applications. Drawing on decades of experience in fiberglass-reinforced plastic (FRP) manufacturing, we take pride in engineering corrosion-resistant solutions that stand up to harsh environments and aggressive chemicals. Our in-house team handles every stage of the fabrication process—from concept and design through tooling, lay-up, assembly, and finishing—allowing us to maintain full control over quality, consistency, and performance.

We focus on delivering custom fiberglass structures that serve industries such as water and wastewater treatment, chemical processing, pulp and paper, power generation, and defense. Our capabilities include the production of ductwork, tanks, scrubbers, hoods, stacks, and other complex FRP systems designed to handle corrosive gases and liquids. Whether a project requires hand lay-up, filament winding, or vacuum-infused composites, we match the process to the application to ensure optimal durability and efficiency.

As a trusted partner to engineers and project managers, we provide full-service support that includes design consultation, 3D modeling, structural analysis, field measurements, and onsite installation. Our team works closely with clients to meet exact specifications, comply with industry standards, and deliver on time—even for the most challenging projects. Through a combination of technical expertise, responsive service, and an unwavering commitment to quality, we continue to provide fiberglass fabrication solutions that perform reliably for years to come.
