Buildings and Shelters

At Orenco Composites, we’re experts in building design. We manufacture buildings and shelters for many different industries, including water and wastewater, telecommunications, power utilities, and transportation.

Pocket in DuraFiber Buildings and Shelters

We build the highest-quality fiberglass reinforced buildings and shelters in the world. Our DuraFiber™  FRP buildings are corrosion-resistant, UV-resistant, and impact-resistant. Orenco Composites buildings and shelters will never rot because no wood is used in the construction of our buildings or doors. All of our buildings are closed-molded with high-strength fiberglass fabrics, not the manually chopped glass that most fiberglass building manufacturers use. In addition, our buildings and shelters are molded as a single-piece, guaranteeing a seamless, leak-proof structure. Our standard, 3-inch (76 mm) foam-core fiberglass walls and roof provide unsurpassed structural integrity, while keeping the interior warm with R-18 insulation. The exterior surface is protected with a high-performance polyaspartic urethane paint, far superior to standard gelcoats. Orenco Composites buildings and shelters are extremely rugged — they can withstand 160+ mph winds and support a 100-lb/ft2 live load. If you want a building built to last — and one that will stand up to extreme weather conditions — choose a high-quality DuraFiber building or shelter.

Fiberglass Treatment Operations Room, Fiberglass buildings and shelters

Did you know that FRP composite buildings are more cost-effective than concrete block or steel buildings? Orenco Composites prefabricated buildings and shelters can be manufactured and delivered quickly as a complete, turn-key solution for your job site. That means your project can be operational in just hours after setting the prefab building in place — hours, not weeks!

Need a load center, lighting, transformers, HVAC, system controls, HMI displays, metering equipment, UPS, explosion-proof components, filters, pumps, or other electronic equipment installed in the building?

Give one of our technical sales reps a call today. We’ll work closely with you and your team from start to finish. We design the product to meet your specific application needs, and we deliver on time, so you can finish your project on time.
