The very first significant structure made of profile metal, which was assembled according to the structural principle, was the famous Eiffel Tower in Paris. Its elements were collected on the ground and superimposed one on top of the other. Today, technologies for the construction of metal structures include dozens of different methods, and for the purposes of:
- Saving metal.
- Strengthening the structure.
- Increasing the service life.
They use such a type of rolled metal as a profile pipe. The most varied format of its cross-section (square, rectangle, trapezoid), the manufacturing method (for example, hot or cold rolled) and the grade of steel (alloy) used for the manufacture provide developers (architects) with ample opportunities to bring their projects to life. At the same time you can buy a profile pipe of any size and shape of a profile in online format with using the website of its supplier to the domestic as well as international market.
The most popular types of shaped pipes in construction
The choice of the shape of a profile pipe for construction depends on the type of structure under construction, its purpose and the magnitude of the maximum load that will affect it during operation. For example, quite often used in construction metal trusses made of square or rectangular profiles (the most common and demanded type) are considered one of the most rational due to:
- Saving metal thanks to the rational shape of the profile and the precise connection of all elements of the grille.
- Equal stability of trusses in two planes and excellent wind flow.
- Convenience and ease of use.
Having an insignificant mass, such trusses are capable of withstanding very significant loads, and the term of their permissible operation is calculated for several decades.
You can select the required profile for the construction of a certain type of metal structure using the supplier's online catalog. The profile rolled metal presented in it has a detailed technical description and marking in accordance with the current GOST parameters.
