Custom Metal Enclosures

Different Types of Custom Metal Enclosures for Electrical Equipment

Any company who needs custom electrical enclosures for their equipment can be provided by any enclosure manufacturing company. They just have to be specific to the design that they want to achieve. This also includes the type of steel material they would like to have, such as – aluminum, stainless and carbon steel. Lead times may also vary so a good communication about what is needed to be achieved is important.

Also, there is an option for an enclosure to be customized – via silkscreen or engraving. In addition to this, a clear understanding of the NEMA or IP rating needed for the specific enclosure will be helpful in communicating to a certain manufacturing company of the enclosures needed to be designed.

Enclosure types

There are several types of customization a company can choose from wall mount, free-standing, floor mount, JIC and through. It is important to note that the size of these enclosures is not limited, they can be built according to the needed size for the electrical equipment. One of the most common ones is the free-standing portable enclosures.

Additional assembly

In regards to the parts of the electrical enclosure, a company can request for an adjustable swing door assembly. This provides an extra space for the inside and the outside for the enclosure for the specific electrical equipment. This will allow the company to easily assemble the electrical equipment inside the enclosure. Doors can be made of solid metal, a feature window, and cutouts or mounting holes. Different applications call for different customization needs. There are also clamps, latches, turn handles, and lock options if you would like an added security for your electrical enclosure. For other seal options, there are strips, die-cut, and bulb extrusion. This enables the enclosure to protect your electrical equipment inside. Communication is the key, let your manufacturer know of what other types of features that you would need.

Other Features

The other feature that you can add is studs and nuts. It can be placed on the back panel of the enclosure of wherever you need them for an efficient installation. There will be no need to drill or tap mounting holes and this will also save your company resources and time. Additionally, there can also be gland plates that can be placed through custom cuts and holes. This can be placed on either side or top/bottom part of the electrical enclosure.

Different customizations for different applications are needed. Some of the companies manufacture electrical enclosure for different industries, such as fire protection, food and beverage, water treatment, power generation, communication/telecom companies, transportation, chemical, wastewater management, petrochemical, and oil and gas. One should note however that there are companies that only specialize for specific types of industries. Message the manufacturing companies to know more.


Lastly, do not forget to be specific about the different protection you need for your electrical enclosures. Most of the common protections enclosures can have are corrosion-resistant, water and dust ingress, hose-water resistance. There are also submersible enclosures for marine offshore companies.


Stainless steel mobile wheel for NEMA enclosures

Additional NEMA 6 Information

Stainless steel mobile wheels for NEMA enclosures

Stainless steel mobile wheels for NEMA enclosures

NEMA 6 enclosures are available in carbon steel, 304 & 316 stainless steel and available with continuous hinges, mounting feet, stainless caster wheels and special fittings for any type of applications. NEMA 6 enclosures have a variety of sizes ranging from small wall mounts to single-door medium size floor mount styles. We are also offering a stainless steel passivation for companies who would like to have the extra feature.

Materials for NEMA 6P Submersible Enclosures


NEMA 6P enclosures are manufactured from 204/316 stainless steel for any use in industrial applications – in specific occasions, these enclosures are manufactured from plastic made for inexpensive electronics. Our submersible NEMA 6P enclosures are used for any type of application where there is a need for water submersion. If there is a need for any use of corrosive materials (salt water) and caustic where the application indicates the necessity the use of those, then the NEMA 6P stainless steel submersible enclosures would be a good fit for you. Majority of the industrial applications creates the need to use 304 and 316 stainless steels. For 316 stainless steel, these are commonly used in offshore platforms and naval applications. In addition to this, the customer should decide the specifications for certain applications (for temperature, seal resistance, depth submersion).

We offer customizable NEMA 6P enclosures that will suit your needs. We are offering NEMA 6P enclosures of different sizes from small wall mounts to two-door floor mount models. Also, like in NEMA 6, we also offer passivation for more corrosion protection and this is available by request.

Additional accessory: Stainless Steel Casters

In addition to the more specifications that are requested for NEMA 6 AND 6P enclosures, provider also offers stainless steel casters to enclosures for any applications that would need transportation of enclosures. Stainless steel casters are non-corrosive material so it is safe to use for NEMA 6 and 6P enclosures.

Our 4″ & 5″ stainless caster wheels can hold weight up to 300 pounds per caster (1,200 pounds for 4 wheels) and these wheels can withstand any application that requires the exposure to corrosive materials and liquids. Despite its weight capacity, these casters are also ideal for the lightest duty applications where the enclosure should be totally immobile when the caster brake is applied.


Stainless Steel Casters: Unique Brake Feature


This stainless steel caster wheel has a unique brake feature that locks both wheel and the swivel bearing simultaneously. Our “Total-Lock” feature for our stainless caster wheels ensures that when the wheel is totally locked, the swivel caster is totally immobile and will not move. This fantastic combination of wheel brake and swivel lock is important for the safety of some specific applications. This accessory is only made by special request of the customer.

Stainless caster wheel features:

  • Swivel Construction – Stamped steel.
  • Swivel has a double ball bearing.
  • Gray Non-marking Soft Rubber
  • Gray Polyurethane, Black/Gray Polyurethane
  • Blue/Gray, Red/Gray and Orange/Gray Polyurethane Wheels have precision sealed ball bearings shielded by full thread guards.
  • Polyolefin wheels do not have ball bearings in the wheel.

Mobile NEMA 6, 6P Enclosures

Mobile NEMA 6 and NEMA 6P Enclosures for Mining with Non-Corrosive Stainless Steel Wheel Casters

There evident continuous business opportunities in the mining industry today, several manufacturers – especially companies who produces NEMA enclosures – are engineering & launching products that are designed specifically for use in mines. But because of severe, harsh environments for electronic products, there is an ongoing demand for well-designed, & quality enclosures.

Submersible NEMA 6P Enclosures Defined

A typical example of a submersible NEMA 6P enclosure would be a stainless steel box used for electronic controls in a power plant or an offshore facility. Also, Submersible NEMA 6P I used for any indoor/outdoor security systems that need more water resistance and protection. NEMA 6P Enclosures are typically are more expensive due to the stainless steel material cost and require skill craftsman for manufacturing.

  • Custom Electrical Conduit Hubs & Pipe Flanges available
  • Heavy Duty, Corrosion Resistant Stainless Steel (grades 304 & 316)
  • Powder coated, Light Weight & Strong Aluminum Alloys (5052, etc)
  • Tough Marine Epoxy Coatings available for specialty applications

NEMA 6 Application

NEMA 6 enclosures are generally manufactured using the following materials: aluminum, stainless steel, plastic, fiberglass (FRP) and other non-corrosive, water-resistant raw materials. An exception to this, all NEMA 6 enclosures made from carbon steel requires an extra protective coating to avoid steel corrosion (rust.) This means that NEMA 6 carbon steel enclosures are used for temporary water rain and other liquids that don’t cause corrosion.

These enclosures are generally used in applications that needed to protect equipment for temporary submersion in water with the exception of salt water, high-acid fluids, any oils or flammable liquid material. One example of its use is any work that requires any heavy wash down for cleaning or any temporary exposure to rainwater.
