Below is a list of Aluminum Enclosures manufacturers from 8mmerce-city, Colorado. Aluminum enclosures house and protect electronic instruments or equipment from damage or interference. Because these enclosures can be used indoors and outdoors, they must protect their contents from a variety of weather conditions as well as from dust and dirt. If not shielded, electromagnetic interference (EMI) can also disrupt the performance of the circuitry inside the enclosures.
