Production of metal structures of columns.

The metal structures of the columns are supporting elements in the structural scheme of the object being built, and are usually made of wide I-beams or various rolled profiles. There are also such types of metal structures of columns, which are made from pipes of different diameters or from metal corners. Usually, such metal constructions of columns are used by low loads.

The metal structures of the columns differ by cross-section type:

• Rectangular.The profile of this type of metal structures of the columns is made in the form of a geometric contour - a quadrilateral. The most common variant of this type of section is a square.
• Round.These metal structures of the columns have a section in the form of a circle. Most often, they are made of steel pipes.
• Double-breasted. The cross section of these metal structures of the columns is also called I-beams, as it resembles the letter "H" in shape. Metal structures of columns with a two-beam profile can be both of the same length and width of the section, and differ from each other.

The metal structures of the columns are also different by production technologies and methods:

Welded metal structures of the columns are made using automatic welding. The raw material in production is metal sheets, which are first stretched and rolled into the desired shape (usually in the form of a double-beam or rectangular profile). To carry out this operation, a special welding machine is required.

Rolled metal constructions of columns (round section) are made using the methods of hot seamless rolling from metal sheets. First, the metal parts are heated, then they are stitched. For the production of rolled metal structures of the columns, a special machine is used, on which the blanks are rolled.

Metal constructions of columns are produced with constant and variable cross-section. There are still metal constructions of columns with a stepped section. In construction of metal structures of columns can be combined constructive forms to give the columns sophistication and exclusivity. And only one type of metal structures of the columns can be used, depending on the terms of the project technical specifications and the client's personal wishes. Note that the process of designing the metal structures of the columns is considered from the point of view of reducing the metal density. Therefore, sometimes it is necessary to change the cross-sections, which leads to a decrease in the consumption of metal, necessary for the production of metal structures of the columns.
