Composites USA shelters are designed and manufactured for rugged industrial use where part weight and contact with corrosive chemicals or sea water might be a concern. Although designed for industrial environments, these shelters also receive the same fit, finish and attention to detail that our electronic housings for radar and instruments have. Shown on this page are several views of a typical custom shelter. This shelter is used to vent hazardous gas cylinders to scrubber systems to prepare the cylinders for refilling. This special design includes insulated walls, single and double access doors, internal room partitions, roof skylights, integral vent connections with dampers, reinforcement steel incorporated into the walls to allow wall mounting of shop tools, and many other custom features. The shelter in this case was installed with Composites USA field crews and connected to Composites USA scrubbers. Each shelter design is rigorously checked by our composite structural engineers for wind, snow and operating loads. The laminate begins with a resin rich corrosion barrier, with either gel coat or reinforced with a fiberglass or synthetic veil and several layers of random chopped strand mat. The structural portion of the laminate is constructed with a combination of random chopped strand mat and continuous strand glass, biaxial, unidirectional or otherwise oriented to meet the design considerations. These layers are gradually built up to the final required thickness. Large sections may be cored for additional stiffness and strength. The top exterior layer is usually applied with a resin pigmented to the customer's preferred color choice, for long-term color stability, which will not chip or flake off. In this way, the color is molded in, part thickness and reinforcement uniformity is carefully controlled, and problems with typical trouble spots, such as voids and inside corners, are avoided. With a Composites USA enclosure, you get a shelter designed to the latest codes, and quality audited to MIL-I-45208 and Factory Mutual standards. All resins used are corrosion resistant polyester or vinyl ester, with flame retardant options available.
