Electrical enclosure manufacturing is not a one-size-fits-all process and requires more than basic sheet metal fabrication services. Each component for custom enclosures must meet exacting dimensions with additional hole patterns, ventilation requirements, unique geometries, weld specifications, and finish requirements to meet customer design specifications.
Precision Steel Services provides build-to-print electrical enclosure fabrication services for industrial OEMs, equipment manufacturers, control system integrators, and other businesses that require finished metal sub-assemblies with custom specifications.
Our capabilities at our facility in Farrell, PA, include advanced laser cutting, water jet cutting, CNC machining, punching, press brake forming, welding, powder coating, and mechanical sub-assembly. With all of these services available through one fabricator, OEMs that partner with Precision Steel Services for custom electrical enclosure fabrication projects maintain greater consistency across project volumes with more competitive costs and expedited turnaround times.

Custom electrical enclosures have a broad range of definitions and specifications, but generally these are fabricated metal housings manufactured to customer-supplied dimensions, material specs, cutout patterns, ventilation requirements, and assembly details. Unlike stock off-the-shelf cabinets used for general-purpose applications, custom enclosures are built to accommodate application-specific electrical controls, equipment layouts, mounting points, environmental requirements, and production processes.
Precision Steel Services manufactures electrical enclosures from customer-supplied drawings, CAD files, and other production documentation. While our team can provide some support on manufacturing processes and material choice, we do not provide enclosure design or electrical engineering services. Instead, our role is to convert your approved designs into highly repeatable fabrications with quality finishes and reliable performance.
A typical enclosure project may require additional coordination and planning between different operations to keep production optimized for expected volume. Our team will manage the following procedures and communication between each station, keeping logistics simple and streamlined for customers.
By managing all processes through a singular service provider like Precision Steel, customers can keep costs low while maintaining greater control over scheduling, part flow, fit-up, and final assembly quality of their custom electrical enclosures.
Precision Steel recently completed work on a custom electrical enclosure project that involved fabricated mild steel panels, formed components, welded construction, powder coat finishing, and some unique application-specific louvers that required new tooling.

We have continuously expanded our facility to include new fabrication equipment that allows us to take on larger, more advanced, and technical manufacturing jobs. All of the services required to fabricate the primary enclosure happen within our contained production workflow. This includes individual panels, structural components, welded assemblies, and finished sub- assemblies while maintaining consistent oversight on tolerances, part compatibility, and consistency.

This project was an excellent example of the full capabilities of Precision Steel. From utilizing a full array of modern equipment to scaling production from initial units into final volumes that kept all fabrication work under one roof.
Custom enclosure projects frequently start with individual units or low-volume production releases before transitioning into full-scale fabrication. Once the customer confirms the custom enclosure meets or exceeds its requirements, our facility is optimized to transition the design into scheduled or higher-volume production quickly.
We have the capacity to support:
If you’re seeking a fabrication partner capable of offering start-to-finish manufacturing services for your custom electrical enclosures, consider Precision Steel Services. With complete control over all required manufacturing processes, our facility makes it easy to start with small runs and quickly scale production to meet demand. Contact us today for more information or to receive a detailed quote on your project.
What information should I provide to get a detailed quote for my enclosure design?
To get started, our team needs approved drawings or CAD files of the enclosure, material specifications, required dimensions, cutout and ventilation details, welding requirements, finish specifications, order quantity, and desired delivery schedules. Additional information regarding expected annual volume or anticipated repeat orders can help but is not required.
What materials and thicknesses can Precision Steel use for custom enclosures?
With a vast array of advanced fabrication equipment, there are very few material restrictions when it comes to manufacturing electrical enclosures. We can use any desired material without difficulty.
Can you add custom louvers, holes, or proprietary ventilation patterns?
Yes. We use CNC punching, laser cutting, water jet cutting, and other subtractive CNC machining centers to produce custom features like louvers, slots, holes, and ventilation patterns. When standard tooling does not meet design requirements, we can develop custom tooling for more advanced requests.
Does Precision Steel provide any design or engineering services?
We are primarily a build-to-print manufacturer of electrical enclosures. Customers should provide all approved designs, CAD files, and production documentation during the intake phase for our team to accurately quote and produce the intended design.
Can you support high-volume projects?
Yes, we have the capacity to provide the same level of quality fabrication work on small batch runs as we do for high-volume production runs. Our in-house manufacturing capabilities allow us to keep costs competitive and lead times aggressive.
