What we do, who we do it for
We support a wide variety of panel and enclosure assemblies, including a wide range of UL-certified and NEMA-rated enclosures. Our plant floor is capable of producing welded, adhesive bonded, and riveted enclosures, frames, and cabinets.
We focus on building higher-level assemblies of mechanical parts and specialize in hinge and door mechanisms. Additional services include populating assemblies with passive devices and in-house painting and powder coating. We also offer custom packaging, skidding, and crating right off the assembly line. Our Quality Control department utilizes special equipment to thoroughly review our assembled products and ensure quality before they are shipped to you.
