Orenco Composites offers multiple enclosure models and sizes, from mid-sized cabinets to our larger, dual-door valve enclosures. These corrosion-free enclosures provide the ultimate protection for your equipment.

Our DuraFiberTM fiber-reinforced polymer (FRP) enclosures are vacuum-infused to form a single-piece structure; they're not manufactured using spray-up or constructed of bolted-up individual panels. No wood is used in these structures, and they have insulating values up to R-24.

Project Profile:
Backup Power Supply

The client needed to protect back-up power supply equipment for a major sporting event. The extra capacity accommodated power needs for audio and video equipment.


The fiberglass-reinforced DuraFiber enclosures had to fit the equipment and fit into the site. Because of the variety of molds we have, we were able to meet the client's needs on both counts.

  • 72" wide x 82.5" high x 96" long
  • 2 doors, each a custom size
  • 3-point door latches
  • Skid-mountable

The walls and roof were integrally molded using a vacuum-infusion process, which adds to the strength of the enclosure.
