What material should a gas box be made of?

A gas box is one of the mandatory components of a gas installation. It is very important to match it in terms of functionality. This mainly means its good condition for a long time, which also has a positive effect on the valves and other elements inside. It is therefore crucial that the box is made of solid material, resistant to mechanical damage and other negative factors.

Gas box KEN System G056/P BAARD B-056-2 Gas boxes are made primarily of stainless steel and galvanized steel. The first of these are well protected against corrosion, they look nice, so we have an ideal combination of aesthetics and functionality. We can say the same about a galvanized box. It is also not afraid of rust, but it does not look as good as a stainless gas cabinet. For this reason, it is powder coated. This improves its aesthetics and additionally strengthens its protection.

It is also worth knowing that a gas cabinet can also be purchased from other materials, such as polypropylene. When installing such a box, remember that the valves must have specific dimensions, approximately 25x30x17 cm. It is very easy to install, durable, lightweight and available in many different colors. Its low price is also worth noting. An interesting option is also a gas box made of laminate, very competitively priced compared to other types of boxes. Easy to install and transport.

What dimensions should a gas box have?

One of the most important parameters regarding gas boxes is their size. Its size depends, among other things, on what is to be inside it. In most cases, two standard sizes are chosen. One of them is a gas box in the size of 30x30x20 cm, in which there is only room for a gas valve. The second one is larger - 60x60x25 cm, so you can place a gas meter and a gas pressure reducer in it. Both solutions, both the 60x60 and 30x30 gas boxes are - as we mentioned - standard solutions, but there are no obstacles to choosing a gas box of other dimensions, which is tailored to our individual needs.

Where should I place the gas box?

The gas box can be placed in different places, depending on the one you choose. You can choose a freestanding gas box , a wall-mounted gas box and a concealed gas box.

These are models with their own supporting structure and have a rear wall (back). They can be mounted on a stand or pedestal, as well as in a fence.

Another one - a wall-mounted gas box, as the name suggests, is mounted on the wall of the building. It can be placed on the surface of the facade or partially embedded in the facade. Another option is to make it flush with the wall surface.

Sometimes the best solution for hiding the gas connection is to place it in a flush-mounted gas box. This type of cabinet can also be mounted in a recess in the building wall, inside the building's facade.

Regardless of the type of gas box , the gas box key is also very important, as it allows us to effectively close the door, protecting the connection against access by unauthorized persons.
