Production and dimensions of the column beam
Like other I-beams with parallel flanges, the welded column beam (marked K) has a transverse profile in the form of the letter H. With thicker flanges and walls, the column beam can withstand significant longitudinal loads.

The weight of the column beam is greater than that of other types of welded I-beams — from 41 to 291 kg/m. The ratio of flanges to walls is 1:1.

Dimensions of the column beam: height 2 m; width of the wall and flanges — up to 0.8 m; thickness of the wall and flanges — up to 4 cm; maximum length — 20 m.

For the production of welded column beams, hot-rolled sheet steel is used, cut into strips of equal width. It is allowed to manufacture a welded column from different types of steel. Walls or flanges can be perforated.

In the table of beam sizes K you can choose welded beams from 20K1 to 40K5. The first digit indicates the nominal height of the I-beam in centimeters, the letter is the profile type, the second digit is the number in the group of standard sizes.
