Steel I-beam (GOST 19425-74),
the hot-rolled steel I-beams (GOST 8239-89),
I-beams with parallel flange edges (STO aschm 20-93)


Steel I-beam from carbon and low alloy steel. 

GOST 8239. The design and dimensions
GOST 535, GOST 19281. General technical requirements

Steel I-beam steel special.

GOST 19425-74. The design and dimensions
GOST 535-88. General technical requirements


Used in large-panel, industrial and civil construction for overlappings, columns of steel structures, bridges, towers and hanging rails.

Special I-beam GOST 19425-74 available types:

 

 

Двутавры стальные горячекатаные


  • С - for reinforcement of shafts;
  • М -steel I-beam.

Accuracy rolling made:


  • high precision - А
  • ordinary precision - В.

 

In accordance with the order of the beam made of length from 4 to 13 m:


  • lengths;
  • multiple lengths;
  • gauge length with the residue up to 5% of the batch weight;
  • of random length.

 

The rest are profiles of length less than 3 m.

At the request of the customer can be manufactured profiles of limited length within off-gage length of over 13 m.

The first two digits indicate the height for this group profiles, see

The index after the first two figures, the profiles across the width of the shelves:

With a slope faces internal shelves With parallel flange edges
without the letter U - ascobolaceae (less than the width of a normal I-beams);
M - for hanging rails B - normal;
W - wide shelf;
D - mid shelf - additional series flange width between normal and wide shelf beams;
To - column flange width approximately equal to the height of the profile.
The number after the index determines profilemaster in this series (for wall thickness and shelves).
If you have one of profilemaster figure is not specified.
The indices A, b and C indicate the difference in size from STO aschm 20-93:
  • A - dimensions according to ASTM A6;
  • В - dimensions ВS 4;
  • С - sizes JIS G 3192.
The "U" at the end of the designation indicates the performance profile in the enhanced version.
The cross-sectional area and weight of 1 m of length of sections with indexes "A", "B" and "C" are accepted according to standards.

  • I beam STO aschm 20-93.

    Currently, the main manufacturer of I-beams in Russia is the Nizhny Tagil metallurgical combine (NTMK), which makes products as Standards, and its technical condition (STO aschm 20-93), is somewhat different from the standard.
