McClarin Plastics, LLC is a leading provider of premium quality fiberglass reinforced plastic molding and fabrication services.


Fiberglass Reinforced PlasticWith a reputation built on a solid foundation of 60+ years experience, we deliver solutions that meet your volume, performance, and cost objectives.

We have expertise in engineering design & materials science to deliver structures and components with several notable advantages. Fiberglass reinforced plastics (FRP) are known for their natural corrosion resistance and offer outstanding performance for various service environments. Additionally, components fabricated with FRP have higher strength-to-weight ratios, superior durability, and much lower costs compared to other materials.

By leveraging either open, cold, or closed molding options, we are able to create large-scale and complex forms with exceptional attention to detail and tight dimensional tolerances for fiberglass reinforced polymers. The versatility of FRP allows us to mold virtually any shape or configuration for your applications that require flexible materials, such as ductwork, interior and exterior lining, and others.

Production advantages of FRP include low start-up costs, inexpensive and adaptable tooling, and fast prototyping. These lightweight components are easier to install (with glue or fasteners) and require less equipment and manpower—lowering your costs even more.  We also offer flexible production volumes and quick turnarounds.

Additional processes offered by McClarin such as dual laminates for fiberglass reinforced plastic components in the rail industry are also available when high strength is needed.

Our integrated approach recognizes the interaction between all manufacturing processes, enabling us to increase the effectiveness of our production, test, and inspection systems to continually improve the quality of our products. Our facility is ISO 9001:2008 certified, meaning all the products we manufacture comply with many industry standards.
