80 to 80 profile pipe: range, technical parameters,

The use of metal structures has now become the norm for the construction of industrial and residential buildings, pavilions, fences and similar structures. And for all this, a metal profile is used, therefore, the weight of 1 meter pipe 80x80x3 mm or with another section is of paramount importance.

We will talk about the manufacture and use of square and rectangular profiles in more detail, because it is also in demand in mechanical engineering, in the oil and gas, ore-dressing and aviation industries, and even in bridge engineering. It should be said that the price of such rolled products depends not only on the section and thickness of the walls, but also on the quality of the steel.

Profile

Assortment

Note. The range of metal products is called a cash or descriptive list of products, for example, a square pipe 80 80, 40 by 40, 20 by 20 and so on. This may include a different configuration and a different section.

• The description of the assortment must be accompanied by the dimensions of the section, as well as the wall thickness, as the mass depends on it, for example, the weight of the pipe 80-80-3 is determined based on one running meter, however, as for the rest of the profile. But these are general parameters - basically the formation is carried out according to certain criteria and for this, all products are divided into three groups.
• The first category includes simple rolling, to which a sheet, strip, hexagon, rectangle, circle or square can be attributed.. The second type, it is shaped products, such as rail, beam, tavr, channel and the like. The third class is the most difficult - it is reinforcing steel, wheels, and so on.

• But besides this, there is pipe rolling, by which are meant all sections of such a profile - a circle, a rectangle and a square (square pipe 80 80 is from this section). In the case of a circular cross section, the documents have a D - outer and a DU - inner diameter (the following figures are in millimeters). But for another profile section, numbers are simply used, for example, a pipe 80-80-3, where 80 is the width in millimeters, and 3 is the wall thickness in millimeters, in addition, their length is dimensional and non-dimensional.
• In the first case (standard or measured length), the same square pipe of 80x80 mm will cost more than in the second, as the cost of production increases (more waste). In addition, seamless or seamless pipes will cost more than electric, as the strength of the latter is much less. When purchasing such material, you definitely need to clarify all these parameters so that the profile corresponds exactly to the operational purpose.

• But the cost of the material may increase due to additional processing, for example, a 80x80 mm pipe can be galvanized, as in the photo above or polished - it is quite natural that an additional charge is taken for such services.. The pricing here is also influenced by the steel grade from which the products are made, so you will have to clarify a lot of positions when purchasing.

Note. Currently, there are many organizations involved in the sale of metal, but there is one caveat - material is sold by both reputable companies and second-hand dealers. In a solid institution, the operator can immediately give you all the parameters, for example, what is the weight of 1 meter pipe 80x80x5, whether it is seamless or welded, and so on - it always has all the data. But dealers usually ask you for a phone number and call back after a while - they simply specify such positions from the supplier.

Technical specifications

Calculation of square profile according to GOST 8639-82

Note. From the upper table you can determine the technical parameters of the profile, for example, a pipe weight of 80x80x3 mm per linear meter is 7.5 kg, and here in the same segment the weight of a pipe 80x80x5 mm will already be 11.44 kg.

Application

Currently, metal pipes with a square section in some cases it is simply impossible to replace with any other materials - instructions in various state standard specifications, building codes and projects based on them simply oblige to use such a profile in certain cases.

Different building frames are usually invisible to the passerby, as they are hidden under the facing materials, but, for example, advertising products allow everyone to see well the metal profiles, of which the same billboards are welded or vertical racks to support them.

The use of such materials is very beneficial both technologically and economically, as the frame structures of pipes are not only durable and light, but they are much cheaper than similar structures made of brick, blocks or concrete.

It is noteworthy that such material has found application in low-rise construction - these are frames for shops, pavilions and offices. But it was quickly adopted in the private sector - now various utility outbuildings are being built from the profile, moreover, a pipe of 8080 mm or 100100 mm is excellent for a pile foundation of a helical pile foundation.

Pay attention to the design that you see in the top photo. The vertical posts, which are the basis of the entire structure, are made of a 80m80 mm profile, for the trellis a rectangular section of 6030 mm is used, but the roof system for the roofing material is welded from a 4040 mm pipe.

In architectural terms, such an arbor fits perfectly into the exterior of the site, moreover, it can stand for more than a dozen years if the metal is cleaned of rust and is regularly painted.

A special place pipe profile takes in the field of fencing country sites, car parks, construction sites and production facilities for different purposes. The advantage of metal here is that such a fence can be made very quickly, by welding or bolting, but it will last for a very long time, moreover, the mechanical strength of steel is several orders of magnitude higher than that of wood or even concrete.

Conclusion

As you can see, the field of application of metal profiles is quite large and very reputable companies and factories are engaged in its production, which, thanks to the flow, makes such materials much cheaper. In addition, when using this pipe at home, many people assemble structures from it with their own hands, which makes significant adjustments to the speed and quality of construction of objects.
