KDM: Your Professional Galvanized Steel Enclosure Manufacturer

Galvanizing is the process where a layer of protective zinc coating is applied onto the steel surface so that the steel will become immune to rust.

Therefore, KDM galvanized steel enclosures are a cost-effective alternative to stainless steel while enjoying the mechanical properties of carbon steel.

KDM has been manufacturing steel enclosures for almost two decades and has begun to provide the galvanized steel option for years.

Over the years KDM has accumulated a good amount of experience in the use of galvanized steel for manufacturing as well as acquiring high-quality galvanized surfaces.

Compared to the powder coating option, galvanized steel is superior in terms of maintenance.

Because for powder coating, if there are scratches on the surface where the coating layer is worn off, then the entire protection layer becomes almost ineffective instantly.

For the galvanized steel option provided by KDM, on the other hand, if the same scratches are on the surface, the galvanized zinc layer will still protect the steel structure since zinc always reacts with oxygen ahead of steel.

Therefore, even though KDM galvanized steel enclosures come at a slightly higher price compared to powder-coated steel enclosures, for environments where physical damages are more frequent galvanized steel enclosures are the more suitable option that requires much less cost on maintenance.

Galvanized Steel Enclosure Designs

Like I’d told you earlier, these types of enclosures come in different designs.

So you’ll find that this variance is essential especially when it comes to selecting a design which suits your needs.

However, the designs for galvanized steel enclosure ordinarily come in two major forms on the basis of a number of doors.

Single-Door Galvanized Steel Enclosure

This simply refers to the type of galvanized electrical enclosure which features one door.

It thus implies that you can only use that one door to access the internal sections of this enclosure.

At the same time, some come with multiple double doors also fitted in different parts of the enclosure for easy accessibility.

Also, you can get customized designs that suit your preferable indoor and outdoor needs.

Quality Standards for Galvanized Steel Enclosure

Well, the definition of how good or bad a product is lies in its quality.

And measuring quality standards is also an equally fundamental task.

The truth is that when it comes to galvanized steel electrical cabinets, quality is an element that you can never compromise.

And in this case, we want to look at some of the key quality standards which outline the suitability and performance levels of these units.


This is the group that is responsible for defining the standards of different galvanized steel electrical boxes.

This standard quite often describes the type of grade of such cabinets, and in most cases, it targets the US market.

NEMA necessarily tends to rate these types of enclosures against the various possible environmental vulnerabilities.

Also, NEMA often conveys the ingress progression for enforcing compatibility safety and performance.

IEC 60529

It refers to a quality standard which you use for assessing the performance levels and measures of this enclosure by various elements.

In the European Union region, it’s mostly known as IEC 60529.

The IEC rating for every IP level gives a measurement for a specific quantity of water that should get inside the enclosure.

IEC quality standard also gives a measure for the cabinet about its ability to protect components from dust and moisture.


It refers to a quality standard for all types of electronic and electrical components mainly in the European Union zone.

It was formerly known as Directive 2002/95/EC, and it restricts the use of all harmful substances available in electronic devices and components.

What it also primarily does is provide a CE-marking directive for the production of these types of products.

Technical Specifications of Galvanized Steel Enclosures

Selecting the best-galvanized steel cabinet requires quite a thorough knowledge and understanding of its various factors.
