2022 Guide to Fabricated Metal Enclosures: Boxes, Bins, Cages, Containers, Panels and Cabinets

Guide Updated August 25th, 2022

There are many different types of commercial and industrial enclosures that can be fabricated and manufactured from metals such as stainless steel, carbon steel, and aluminum. These include boxes, bins, cages, containers, panels, and cabinets. Even mobile carts like the ones used to store tools in a garage are considered a type of enclosure.

Fabricated Metal Enclosure

What they have in common is that they are all designed to hold or protect other items or equipment, and they all require the expertise of a precision sheet metal fabricator to be manufactured correctly. This is especially true for enclosures intended for use in highly-regulated industries, such as medical, energy, food service, military, or aerospace.

Depending on the project, it can also be extremely important to choose a metal fabricator with the certifications and experience needed for the specific enclosure type that will be manufactured. For example, when a NEMA-rated or UL-certified type 1 508A enclosure must be engineered and produced, EVS is a good choice due to our UL type 1 508A certification status.

Below is a guide to each of these enclosures along with examples to help differentiate between the various types and increase understanding of what they are used for. 

Industrial Metal Box Enclosures

The term “fabricated metal box” is often used interchangeably to describe other, similar items, including the generic “enclosure” but also cabinets and panels, to name a few. They are a common enclosure type with many uses, particularly for electrical utility products. They can be manufactured using stainless steel and aluminum in a wide range of sizes. Box enclosures are fairly straightforward, but there can be any number of variations that can be fabricated, such as galvanized steel boxes, hinged boxes, pull boxes, toolboxes, powder-coated boxes, screw cover boxes, and latch boxes. 

Fabricated Metal Cages & Chassis

Some of the most common types of fabricated metal cages are card cages, sub-rack card cages, and chassis. These are types of electrical enclosures that are commonly found in computer data centers and are used to hold various types of related equipment, including computer servers, printed circuit board cards, and fan assemblies. They are also referred to as equipment racks, rack units, and server cabinets.

Industrial Metal Containers

Most often, when metal containers are mentioned, it is dry shipping containers that are being referred to. These are the large containers that are used to transport products on cargo ships and trains. Other types of large fabricated metal containers include moving and storage “pods” and industrial, modular containers that are often used as alternatives to traditional construction, such as those on building sites. There are also smaller metal containers, such as those that provide stackable storage in industrial settings such as warehouses. 

Fabricated Metal Panels

This term can be a bit confusing, as “metal panels” can refer to multiple products that are completely unrelated. For instance, there are architectural metal panels, which are decorative and often used for aesthetic reasons when designing the facades of large commercial buildings. But the term “metal panel” can also be used to describe smaller enclosures, such as electrical panels. An example of these can be found in every home, often in the garage, and houses all of the various electrical circuits. It is also referred to as a fuse box.

Industrial Metal Bins

This is another term that can have more than one meaning. For instance, there are types of extremely large metal bins fabricated out of steel that have some similarities to metal shipping containers in terms of their size. These are generally rated for both indoor and outdoor applications and can be used for bulk material and product storage, waste containment, and disposal, transportation of materials when outfitted with wheels, and even to secure very large/expensive equipment, such as those used on construction sites, when industrial-grade locks are added. However, there are smaller types of metal bins, generally meant for indoor use, that are essentially interchangeable with metal containers. These are used in commercial and industrial settings, in particular warehouses, and are often stackable to make the best use of space.

Industrial Metal Cabinets

Metal cabinets are essentially a type of metal box with doors. They generally come equipped with inner shelves, racks, drawers, or even some combination of the three. When wheels are added, they are sometimes referred to as metal carts, such as those used in hospitals to transport medicine or surgical equipment. There are metal cabinets that are manufactured for the purpose of securing expensive or valuable items, in which case they may have locking mechanisms on the doors. They are often used as file storage, bookcases, or lockers, like those found in schools and gyms.
