Fiberglass Enclosures

Fiberglass enclosures are made of a thermoset polyester reinforced with glass fibers. Fiberglass can be installed in environments that are constantly wet and is a low-cost alternative for corrosive environments. Fiberglass is impact resistant, chemical resistant and can handle a wide temperature range of -31 degrees Fahrenheit to 300 degrees Fahrenheit.
Allied Moulded fiberglass enclosures are molded with ULTRAGUARD fiberglass reinforced with polyester material. They are designed to insulate and protect electronic components in both indoor and outdoor applications.
Hoffman ULTRX fiberglass enclosures are high-impact resistant and have temperature and chemical resistant qualities. Fiberglass is easily drilled, punched, sawed and the exterior surface can be painted to enhance UV protection.
Fiberglass vs Polycarbonate Fiberglass enclosures have a high corrosion and chemical resistance. They can be used with cleaning solvents, toluene and carbon tetrachloride, as well as mild acids, such as boric acid and aluminum chloride. Direct UV exposure for long periods of time can warp fiberglass and cause it to lose strength. Polycarbonate enclosures have a smooth, more clean looking appearance than fiberglass. They are rated for use in facilities that handle food production, however they do not have as much chemical resistance as fiberglass enclosures.
The Hoffman fiberglass enclosure catalog includes wall-mount, enclosures that range from 6” x 4” x 5” to 60” x 36” x 16”, as well as free-standing fiberglass enclosures as large as 72” x 49” x 24”. Many of the wall-mount instrument housings are available with solid or window doors or covers, and various quick-release latches, quarter-turn latches, handles or screws to secure the door or cover.
