Unlike stainless steel boxes, fiberglass enclosures are cost-effective, lightweight, and easy to modify by drilling, punching and cutting. This last feature is a huge advantage in the field, where often changes need to be made on the fly. The light weight nature of the material makes shipping and installation easier and less expensive.

Did you know that fiberglass is on par with stainless steel when it comes to corrosion and chemical resistance? And when it comes to carbon or lower grade steels, fiberglass is far superior in those categories. It’s also extremely strong and a fraction of the price you’ll pay for a high quality SS enclosure. Plus, fiberglass is an electrical insulator, while metal enclosures materials are electrical conductors.

Allied Moulded enclosures are designed to withstand extreme temperatures and exposure to UV rays. In fact, Allied enclosures far outperform other non-metallic boxes in its ability to withstand UV exposure without degradation. Their unique formula is made to deter discoloration and fiberbloom.
