Custom Electrical Enclosure Manufacturing Services
We manufacture custom sheet metal electrical enclosures for industrial equipment, automation systems, and control applications. From prototype to mass production, our team supports custom sizes, materials, cutouts, mounting structures, and surface finishes to meet different project requirements.With laser cutting, CNC bending, welding, and powder coating capabilities, we deliver durable enclosure solutions with consistent quality and reliable performance.
Key Advantages of Our Electrical Enclosures
Our lockable electrical enclosures protect wiring, switches, and control hardware. NEMA Type 2 through Type 7 and IP65/IP66 options are available for indoor and outdoor applications. Durable steel construction and keyed locks help protect internal components, while authorized personnel retain convenient access for maintenance. Standard and custom configurations are available with accessories such as DIN rails, mounting panels, and pole-mount brackets.
Custom Electrical Enclosure Solutions
Outdoor Electrical Enclosures
Constructed of corrosion-resistant 304 stainless steel, rated NEMA 3R & NEMA 4X. Weather-resistant cabinets designed for external equipment protection.
Industrial PLC Automation Cabinet
Designed for manufacturing, chemical, water treatment and pharmaceutical production lines. Rigid steel housing shields PLC hardware from dust and temperature fluctuation, organizing wiring to meet industrial safety codes.
Double-Door Service Control Cabinet
Heavy-duty sheet metal construction with two lockable swing doors for easy internal equipment access. Pre-cut cutouts fit touchscreens and wiring hardware; scratch-proof powder coating delivers long-term factory corrosion resistance.
Multi-Size Low-Voltage Distribution Cabinet
Multiple standard frame sizes accommodate diverse power load demands. Bottom ventilation slots cool internal components; single lockable door protects wiring from physical damage in factory environments.
Wall Mount Electrical Enclosures
Compact enclosures for control panels, junction boxes, and electrical components.
Freestanding Full-Size Control Cabinet
Self-supporting floor frame built for complete integrated control systems. Modular internal mounting panels support flexible layout of switches, drives and monitoring hardware.
