Steel enclosures have become an essential part of many industries due to their durability, versatility, and ability to provide excellent protection for electrical components. With the use of steel, these enclosures ensure a robust barrier against various environmental challenges, safeguarding the items housed within.

One of the standout features of steel enclosures is the variety of steel types employed based on the specific application. Carbon steel, known for its strength and resilience, is often the go-to choice for many industrial applications. Its rugged nature ensures that the equipment within the enclosure remains protected against physical impacts.

Stainless steel, on the other hand, offers corrosion resistance, making it a preferred material for environments exposed to moisture or chemicals. Its sleek appearance combined with its strength makes it an excellent choice for both functional and aesthetic purposes.

Galvanized steel enclosures are treated with a protective zinc layer, further enhancing their resistance to rust and corrosion. This makes them ideal for outdoor installations where they might be subjected to rain or other elements.

For those seeking a more budget-friendly yet robust option, mild steel enclosures offer an excellent balance between strength and cost. They can be found in various applications, ensuring the safety of electrical components while being economical.

More Information about Steel Enclosures and Junction Boxes

Steel junction boxes, designed to house and protect electrical connections, benefit immensely from the strength and durability steel offers. The depth of these boxes can vary, accommodating different types and amounts of wiring or components. Features such as knockouts further enhance their versatility, allowing for easy modifications based on the wiring needs.

A crucial aspect to consider when selecting steel enclosures or junction boxes is the NEMA rating. This rating provides information on the level of protection an enclosure offers against elements like dust, water, and impact. By understanding the NEMA rating suitable for a particular application, one can ensure that the chosen enclosure provides the necessary protection.

FAQs

What are the benefits of painted steel enclosures?

Painted steel enclosures offer enhanced corrosion resistance, protecting the underlying steel from environmental factors and potential rust. The paint provides a clean, professional appearance, making them suitable for both industrial and commercial applications. Additionally, the painted surface can facilitate easier cleaning and maintenance, ensuring longevity and aesthetic appeal over time.

Mounting Electrical Enclosures

Before mounting to any surface, it is important to understand how the hardware will interface with the enclosure. In many cases, the enclosures will have holes at the corners that can be used to attach any mounting hardware. It is common to see a mounting strut, commonly referring to as a Unistrut, being used with these electrical enclosures. The Unistrut can attach to the enclosure and provide a very strong connection point to either a wall, concrete or pole mount.
 

When mounting to a concrete wall, there are several things that should be considered to ensure it is done correctly. Industrial concrete anchors provide a very strong and reliable connection that can last a very long time. Make sure that the concrete is thick and strong enough for these types of anchors. Once the anchors have been installed, attach them to the mounting strut that is attached to the enclosure using hardware that is designed for that particular type of mounting strut. 

When installing an electrical enclosure on a pole or mass, it is important to make sure that the pole can handle the weight of the enclosure. It is recommended that the pole is made of a very strong rigid material. At least two inch rigid galvanized conduit is recommended. Once the pole has been secured into the ground, strut clamps designed for the size of conduit will attach the enclosure.
