Steel pipe 50x50: where to apply and how to choose

Such material as the 50x50 square tube is very much in demand today when carrying out various construction and repair works. And this is quite understandable, since its qualities allow solving various problems, where traditional materials simply lose in terms of technical and other parameters.

Special features

The popularity of products is influenced by many factors:

1. Reasonably reasonable price of such products. For example, when constructing supports or pillars, it is often more advantageous to use this type of metal than to cast a concrete column.
2. Metal pipe 50 to 50 is very easy to install. In particular, it can be either bolted or welded to anything.
3. Due to its square shape, the product has an increased level of rigidity - that is, it is rather hard to bend.

It turns out that the material is so popular mainly because it has unique technical qualities and an affordable price. In addition, it is able to replace the most diverse elements of the profile reinforcement and, accordingly, significantly reduce the cost of the project (without loss of quality).

The square tube 50 50 is made according to a very simple principle - a standard round shape is made, which undergoes a process of cold or hot deformation. That is, a round billet (also called a “strip”) is inserted into a special press, which gives it a square shape and a predetermined section.

At the same time, the production instruction also includes such a step as quality control of the weld in accordance with GOST and even such an action as heat treatment. Heat treatment is used to relieve mechanical stresses inside the metal.

As for the material of manufacture, we will consider this issue in the table below.

In principle, if we talk about which pipe 50 50 5 is better, then, of course, we must proceed from the operating conditions. If the product will be operated inside a dry and warm room, then carbon steel billet is quite suitable.

And if you plan to lay the structure on the street or in the ground, where aggressive external factors will constantly influence it, then it is better to stop at the second option.

Note! Low-alloy steel with the addition of many third-party elements such as copper or aluminum, although it becomes more stable in the physical plane, but it loses a little in strength. So if you need a pipe 50 50 2 just from such steel that will perform the bearing functions, then we advise you to choose a product with a greater thickness of metal.

That is, for example, a pipe of 50x50x5 millimeters is quite suitable for such operation (the last value is just the thickness of the steel).

Well, if you simplify the information as much as possible, then we can say that this product is most often used as an analogue of a bar.

You can use a square profile for these purposes:

1. As a framework for pipe fences. It is good that such structures do not require very high load-bearing abilities, which means that not a pipe 50 50 4 mm, but 2 is quite suitable.

1. As props for canopies, canopies and ceilings. The only point to consider for such structures is that steel square products do not look very nice.
2. For the device of lags in overlappings and a roof. Here you only need to correctly calculate the maximum allowable length of the product - so that there are no deflections. In order to avoid deformations for floors, it is necessary to use the most thick metal with a large cross section.

Tip! If you are laying metal beams, then it is very important to focus on the weight of 1 meter of pipe 50x50x2 - it is possible that due to the heavy load on the walls, you will have to use not wood as lags, but wood. After all, it turns out that the greater the thickness of the steel, the greater the weight of the lags. Simply put, walls can not withstand such a load.

Details of the ratio of the weight and thickness of the metal walls are given in the table below.

That is, as you can see, the weight of a 50x50x4 pipe, for example, is significantly different from products with a different metal thickness. Consider this when planning a project. Moreover, the cost of the entire work directly depends on this.

Let's take a look at how to “complete the picture”, how such materials are used in real private construction. As an example, the easiest way to take a fence under the flooring.

Mounting a square pipe fence

To work we need a minimum of inventory.

In addition to the square profile itself, stock up on this:

1. A shovel (it is best to buy an "American" - it is easier for her to dig).
2. Peskobeton.

1. Ruberoid
2. Tape measure, construction thread and level.
3. Grinder for cutting pipes.

Well, among other things, at a certain stage, you will need to invite a welder. In principle, you can do without it, but then you will have to fasten the steel together with the help of bolts, and this is inconvenient and time consuming. It's easier and cheaper to invite a welder for a couple of hours.

Layout and preparatory work

So, let's start building a fence with our own hands.

You need to act approximately in this order:

1. We mark two extreme points along the line of the future fence.
2. We drive in these places pegs.
3. Between pegs pull the thread.
4. We mark the points where the intermediate columns will be located (usually the distance between them is 1.5 - 2 meters) and install pegs in these places.

1. In all necessary points we dig holes, the width of which should be 20 centimeters.

After that, a 50x50x4 square tube is taken (2 mm will not be enough for a really solid construction) and columns of the required height will be cut from it. Next we go to the finishing stage.

Frame assembly

Now you need to dissolve the sand concrete with water, wrap the part of the columns that “go” in the ground, roofing material, and then insert the extreme pillars into the pits. Then you need to align them relative to the vertical with a level and fill the free space of the hole with concrete.

When the concrete dries, a thread is stretched between the outermost columns and all intermediate columns are installed relative to it and are also filled with cement mixture.

After the mixture in all pits hardens and the pillars stop moving under pressure, you can start welding. In fact, on this you just need to weld two parallel horizontal lines at the top and bottom of the fence.

When this is done, you can safely fasten decking - because the fence frame of square pipes is ready!

This concludes our review and now we can summarize the article.

Conclusion

We have dealt with in detail what are square 50 by 50 mm square pipes. We considered the scope of application, recommendations for choice, and also got acquainted with a specific example of how a fence is made of such products.

I want to think that the information you need in practice. If the information did not seem to be enough, then we recommend that you also view the additional thematic video in this article.
