You could say that electrical enclosures are NJ Sullivan’s bread and butter. We have been manufacturing professional grade electrical enclosures since our inception in 1958. Originally, NJS started fabricating sheet metal and machining for the Federal Government and private industry. In the early 1970’s N.J.S. began to specialize in products for the electrical construction industry, manufacturing junction boxes, troughs, enclosures, cabinets and bus bars.
We still do!

NJS is a full service custom metal fabrication company. We build fully customizable electrical enclosures for any need and out of most metal products. We have a large fully staffed finishing department that include 4 large powder coating ovens and 4 large spray booths. Our fully staffed 52000 square foot metal fabrication plant includes a large capacity CNC Precision Machining department.

NJ Sullivan is capable of handling all your metal needs, big or small. Contact us today and find out what we can build for you.
