It doesn’t matter whether it’s for outdoor or indoor applications.

If you’ve been keen enough, you’ll realize that most of the enclosures you see outside here in different places are made of stainless steel.

But that’s a topic will handle later on in this guide.

For now, let’s look at some of the key reasons why you would necessarily require stainless steel enclosures.

Why You Need Stainless Steel Enclosure

Listen, the truth is that once you’ve figured out the type of project you want to pursue then definitely you’ll need to find the right enclosure.

Of course, the hustle that comes with selecting the ideal one is never a walk in the park.

But that notwithstanding, it’s vital first of all to know some of the major reasons why acquiring this type of unit would be necessary.

And for that reason, let’s get straight to the point and find out some of these reasons;

· To improve safety and workplace

You see, whether you have an electrical connection in the office or factory, your safety and that of other people around must be a priority.

When you let the cables with live electricity and switches to hang around the workplace area, then you expose people to danger.

Therefore, the best way of preventing incidences such as electrocution from happening is by locking such components inside the enclosure.

Ordinarily, these components tend emitting heat.

And when you fail to regulate the heat, it’s obvious that they will explode, sooner or later.

But then, the design of this equipment is in a manner that allows it to control the temperatures of such components to the necessary level.

And that’s the reason you’ll hardly find one which has exploded due to the rise in temperature.

· To enhance efficiency and performance

Incidentally, it would be pointless to have a high-quality assortment of electrical components if they don’t offer efficiency.

You see you can have all the glowing arrangement, but at the end of the day, you’ll keep delaying to fix a number of them.

But once you have a stainless steel enclosure, the work becomes, easy, convenient and faster.

And for that reason, you’ll be able to increase the performance of all your equipment and operations.

· Prevents vandalism of the electrical components

Let me tell you, the cost of purchasing some of the electrical components that are used in various equipment operation can be expensive.

And so the only way of making sure that unauthorized people cannot access or vandalize them is by housing them inside the enclosure.

The good thing with this type of cabinet is that it comes with lockable doors.

So it becomes easy to secure all the components inside the enclosure and preventing vandalism to a great extent.

The benefits of having a stainless steel electrical box are quite numerous.

One of the most excellent features of this enclosure design is that it has lockable doors.

Unquestionably, this is essential because it protects the electronic instruments and devices from unapproved entry.

It’s the lock that actually controls the access of the enclosure.

You can find them in various sizes, shapes as well as styles.

Well, the truth is that the stainless steel enclosure designs are quite a several and thus we can’t necessarily discuss all herein.

Nevertheless, these are some of the major and common ones that you can easily find in the market.

And as if that isn’t enough, you can also choose to go for a customized design as I had earlier mentioned.

As long as it suits your particular application needs.

Now, let’s change focus and look at some of the quality standards for stainless steel enclosures in the market.

Quality Standards of Stainless Steel Electrical Enclosure

Quality Standards of Stainless Steel Electrical Enclosure

The most compelling aspects revolving around enclosures include the safety, performance and quality standards.

In fact, you can hardly state that a particular enclosure is safe and efficient if it does not meet the respective quality standards.

And it is for that reason that I want to describe to you some of the major quality standards that any enclosure needs to meet.

What’s more important is to note that the specific quality standards are a bit different depending on various factors.

Incidentally, the different quality standards vary depending on the country, or region for that matter.

So without taking much time let’s get straightaway to these standards;

1. UL

It is one of the critical quality standards that any suitable stainless steel enclosure has to meet.

Primarily, it is an abbreviation for Underwriters Laboratories which is the body responsible for issuing this particular standard.

UL compliant stainless steel electrical enclosure

UL Compliant stainless steel enclosure

The UL quality standard mark particularly indicates that the body has tested all the numerous samples regarding the enclosure.

And so when you find an electrical cabinet with the UL mark, you should have it in mind that it meets all the requirements fully.

Therefore, you’re free to go ahead to purchase and also use it.

2. RoHS

This is also another common type of quality standard measure for electronic items and electrical enclosures as well.

Its execution is fully predominant in the European Union market, and in most cases, it restricts the use of harmful materials.

This particular standard identifies and describes the specific levels of various elements which are apparently under restriction.

And for that reason, you can be sure of obtaining a high-quality enclosure should you get one that meets this standard.

3. CE

This is a mark of quality which expresses the conformity of the enclosure with all the necessary safety, health, and environmental protection elements.

Incidentally, this quality standard is also majorly common in the European Union region.

Primarily, it is a declaration stating that the manufacturer of the particular unit meets all the different EC directives.

This quality also symbolizes the fact that the product, enclosure for that matter is marketable within and beyond the EU region.


Now, this is unquestionably one of the most significant and popular quality standards.

It is a standard which describes the quality of enclosures of various grades but particularly those made for the US market.

The NEMA standards essentially rate the electrical cabinets against different types of environmental susceptibilities.

In many occasions, NEMA conveys the Ingress Progression and making it possible for you to enforce compatibility and suitable performance.

Stainless Steel Enclosure Specification

Now, one of the most important aspects that you must have in mind whenever you’re buying this type of unit is the technical specifications.

They’re quite a number, but in this guide, we’ll only look at a few of them which include the following;

· Door

stainless steel enclosures door

Most of the stainless steel enclosures are designed for outdoor applications hence tend to feature at least a single entry.

But in most cases, they come with two doors apparently for easy access to the components and instruments.

· Size

Ordinarily, the size of the stainless steel enclosure depends on your specific needs.

If your application needs are for large-scale purposes, then obviously you’ll go for a bigger unit and vice versa.

And on many occasions, larger sizes are often designed for outdoor applications whereas smaller sizes for indoor applications.

· Compartments

You should also consider the number of sub-divisions that the enclosure general has.

The compartments are the elements which make it possible for you to mount and organize the various electrical instruments and devices.
