nVent Hoffman Steel Enclosures
Steel enclosures are made with carbon or mild steel for indoor and outdoor enclosures. Carbon steel is a strong and cost-effective material however, it is susceptible to corrosion from exposure to moisture and oxygen. Carbon steel enclosures require a powder coating or paint to provide protection from the elements.
Hoffman has the industry’s most comprehensive protection portfolio that meets global and local standards for a wide range of applications. The portfolio for enclosures that are available with mild steel construction include: Wall mount enclosures, junction boxes and free standing enclosures.
Hoffman wall mount enclosures include their INLINE and CONCEPT enclosures. INLINE enclosures have an outward formed body flange to prevent contaminants from entering the enclosure and are available in three cover styles: hinged solid door, hinged window door and solid screw cover. CONCEPT enclosures are ideal for machine control applications and offer the widest selection of sizes and include: single-door, window-door, two-door, flush-mount, sloped-top and EMC models.
Hoffman junction boxes are available in lift-off cover styles as well as hinged-cover models that feature a continuous hinge with clamps for secure latching. Quick-release and quarter-turn latch options are also available.
Hoffman free-stand enclosures include one, two or multi door designs. Some are available with front and rear access and 3 point latches. The Universal free-stand enclosures can be configured to suit a variety of applications. Floor stands are available to provide floor clearance.

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.
