Custom Electrical Enclosure Manufacturing Services

Sheet metal dual-door electrical cabinet with viewing window and pre-punched ventilation holes

We manufacture customizable, lockable electrical enclosures for residential, commercial, and industrial applications. Each enclosure is produced using precision laser cutting, CNC bending, and welding, then finished with a scratch-resistant powder coating to help withstand rain, dust, UV exposure, and extreme temperature changes. These enclosures protect electrical hardware used in automation, power distribution, telecommunications, and renewable energy systems. Standard sizes and fully customized builds are available, with optional mounting accessories to suit your equipment layout.

Core Benefits of Our Industrial 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.

FAQ

Which NEMA-rated electrical enclosures do you manufacture?

We fabricate NEMA 1, NEMA 3R, NEMA 4 and NEMA 4X metal electrical cabinets for indoor and outdoor installation.

Can you customize cutouts for PLCs, switches, and wiring ports?

Yes. We can provide custom laser-cut openings based on your electrical component layout.

What surface finishes are available for steel electrical enclosures?

Options include epoxy-polyester powder coating and a brushed finish for 304 stainless steel.

Are your electrical cabinets compliant with UL outdoor construction standards?

Our enclosure structures follow UL 2202 design specs for exterior weatherproof use.

How do you reduce condensation inside electrical enclosures?

Stamped drainage channels and continuous EPDM foam gaskets help manage moisture and reduce condensation inside the enclosure.

What material thicknesses do you use for sheet metal electrical cabinets?

We use 1.2mm–3.0mm cold rolled steel and stainless steel based on project load requirements.

Do you provide small-batch custom electrical enclosure fabrication?

We support both low-volume prototype orders and mass production of custom metal electrical housings.
