Enclosures & Cabinets
NEMA-rated electrical enclosures, control cabinets, and equipment housings fabricated from sheet metal.
Fabricated enclosures and cabinets protect electrical, electronic, and mechanical equipment from environmental hazards, unauthorized access, and electromagnetic interference. From simple junction boxes to large walk-in electrical rooms, enclosure fabrication combines sheet metal skills with precision assembly. NEMA ratings define the environmental protection level: NEMA 1 (indoor general), NEMA 3R (outdoor rainproof), NEMA 4 (watertight), NEMA 4X (watertight and corrosion-resistant), and NEMA 12 (industrial dust-tight). Material selection follows the rating, with carbon steel for NEMA 1/3R/12, stainless steel for NEMA 4X, and aluminum for lightweight or non-corrosive applications. When specifying custom enclosures, provide detailed requirements for NEMA rating, material, finish, internal mounting provisions, cutouts for connectors and ventilation, and any thermal management needs. Experienced enclosure fabricators can assist with design optimization for manufacturability and suggest standard components that reduce cost.
