Because safety is such a concern today, we build our enclosures primarily out of our own Alumiflex® material, with safety margins being that of products being lifted overhead and exceeding seismic ratings under, ASME B30.20, B30.9, and BTH 1, as well as Telcordia GR 63.  DDB has led the industry by backing its claims with certified data points from 3rd party engineering in order to stay ahead of the competition. We blow the competition away with our enclosures taking more wind than the competition, tested to meet or exceed ASCE 7-10 with optional 200mph options available. Take a look at our WIND STUDY. Whether on the coast of Florida or the mountains of Colorado or even on the San Andreas, we have you covered.

This does reduce the protection against windblown dust, but this protection can be enhanced by using screens and/or air filters placed in the louvered openings. NEMA 3R enclosures offer superior protection in both indoor and outdoor environments. Outdoor: water elements, rain, snow, formation of ice, falling dirt, blowing dirt/dust. Indoor: protects from all the same elements and indoor issues such as water / moisture drops from above.
