The 20×20 galvanized junction box is a very robust metal box used for the physical protection of electrical connections and also for providing conditions for electrical branches. The main purpose of using these boxes is to increase the safety of cabling networks and also to create proper management of electrical connections and branches.
The geometric shape of this metal box is a square cube, so its sides have identical dimensions of 20 centimeters. Of course, in addition to this size, numerous other dimensions such as the 10×10 galvanized junction box and the 15×15 galvanized junction box have also been designed and manufactured with exactly the same material and structure.
The various sizings of these boxes depend on the scope of your cabling project. In other words, the greater the number of branches and connection terminals inside the box, the larger the sizes of this product you will be forced to use.
The 20×20 galvanized junction box is among the relatively larger sizes. Of course, this is not a final size, as you can also request a custom galvanized junction box with any dimensions you desire from manufacturing companies. However, the mentioned types are standard dimensions with very wide usage statistics in various industrial projects.
We will discuss below exactly what advantages and benefits these parts have and what their types are. Of course, much more extensive information regarding these same boxes in smaller product sizes has been provided, which you can also study. So, if you intend to purchase these boxes, be sure to pay attention to the continuation of the article.

The most important advantage of the 20×20 galvanized junction box is that it has a fully galvanized coating. The type of galvanization process in these junction boxes is hot-dip. Of course, as you know, the cold galvanizing process is also sometimes used for strengthening metals, but hot-dip galvanizing is the best type of strengthening for metals.
You can easily use the 20×20 galvanized junction box in industrial environments, sheds, workshops, and also environments with high levels of humidity and existing stresses. Consequently, you should not worry about the corrosion and rust of these junction boxes. This unique feature will also be maintained over a long period of time.
۱. High resistance to corrosion
The 20×20 galvanized junction box is resistant to corrosion and rust due to the galvanization process. This feature is especially very important in humid and industrial environments, as it prevents premature damage and the need for frequent repairs.
۲. High durability and long service life
Due to their resistant material, these boxes have a longer lifespan compared to plastic boxes. Resistance to pressure, impact, and harsh environmental conditions increases their durability, so that they perform well even in adverse weather conditions.
۳. High safety for electrical connections
The 20×20 galvanized junction box, due to its strong and insulated structure, guarantees the safety of the electrical connections inside them. This feature is very essential for protecting terminals and connections against potential hazards such as short circuits or physical damage.
۴. Resistance to harsh environmental conditions
This type of junction box is very suitable for industrial environments, open spaces, or areas with extreme temperature changes and varying weather conditions. The ability to resist moisture, dust, and high temperatures makes them ideal for use in these environments.
۵. Ability to route various types of steel conduits
Another advantage of the 20×20 galvanized junction box is that various steel conduits can easily be routed into it. This feature is especially useful in complex installations or projects requiring complex and strong connections.
۶. Maintaining the health of electrical equipment
These boxes can effectively protect electrical equipment from environmental and mechanical damage. Given their strong and insulated design, they are able to prevent dust and water from penetrating into the box, thus maintaining the health of the internal equipment.
۷. Variety in dimensions and design
The 20×20 galvanized junction box is manufactured in various dimensions and designs, so they can be easily selected based on the needs of the project and the environment. This feature allows them to be easily installed in a variety of small and large projects.
Junction boxes are manufactured in various materials such as plastic and galvanized. The main difference between these two models lies in the body resistance and their applications. The 20×20 galvanized junction box, due to its high strength and impact resistance, is considered a better choice for industrial projects and harsh environments, while plastic boxes are lighter and more suitable for low-risk environments.
Providing a completely closed and isolated space for connections and the terminal location inside the electrical junction box is extremely important. Generally, cable connections are vulnerable to the smallest external factors. Consequently, the 20×20 galvanized junction box can provide a completely isolated environment for the cable connections, thereby preserving both the safety of the cabling network and the external environment.
By using these boxes, you cannot have any completely unintentional physical contact with the connection and branch points. These boxes prevent dust, fluids, and any external factor such as various creatures from entering the box. The reason for this is the presence of a completely resistant cover on the box, which is attached to the main body of the box using a number of screws.
If you have paid attention to the body of the 20×20 galvanized junction box and its other sizes, you will see that on each side, there are several cavities or punches. The punches are designed so that you can easily connect the conduits carrying the cables to the intended box. If you want to route the cables from outside the box into it, the cables will practically be damaged due to the creation of a few centimeters of distance between the conduit and the box.
However, when the steel conduit is routed somewhat inside the electrical junction box, then you can carry out the connection and branching operation with the highest level of safety. The size of these punches is determined according to the dimensions of the conduit, some of the most common of which are sizes PG13.5, as well as PG16 and PG21. Of course, some custom junction boxes are without punches. As a result, at the project site, you can use special tools to create any size of punches in the box body so that you can route your intended conduit, which has a specific size, into the junction box.
In addition to the 20×20 galvanized junction box, you can purchase various types of aluminum junction boxes in different sizes as well as polymer types in the market. Each of these electrical boxes has different structural features, and you must select each according to the project situation. Galvanized types are usually also known as industrial electrical boxes.
Of course, in some work environments, using aluminum types is also permissible. However, you must note that an increase in the existing stresses in an environment can have heavier impacts on boxes with a weaker structure. To select the correct type of these junction boxes, it is recommended to definitely consult with an expert in the field of building electrical cabling.
Rafi Industrial Group designs and manufactures a collection of various types of electrical junction boxes with the highest level of quality and standards. The price of these electrical junction boxes, due to being domestically manufactured and maintaining market balance, is very affordable.
