Metal structures of various types are an integral part of modern construction. It doesn’t matter whether it is concrete reinforcement or the frame of a building, even supporting supports are most often made of metal.

The technologies for manufacturing such structures vary, but each consists of three main stages: procurement of the necessary elements, assembly, welding of nodes. Now metal structures use assembly materials, that is, those that were originally made for specific purposes. Of course, each design has its own technical standards, in accordance with which the necessary materials are selected. For example, if the design provides for a beam weight of two tons, then five cannot be used.
To assemble the structure, a place is selected near the construction site where the work will take place. Either material or assembled small elements are brought there. But the structure itself is not allowed to be transported over long distances. When designing, the architect must calculate the weight on each of the beams, as well as the points where reinforcement needs to be made.
With a wrong calculation, everything can fail. Welding is also an important element. Naturally, this should be done by professionals, and a special engineer should follow the whole process, since strength depends on welding, as well as on correct pressure calculations. Steel is usually used, but now cheaper but stronger alloys have begun to come into fashion.
