I-beam, also known as steel beam (English name Universal Beam), is the cross section of the I-shaped shape of the strip of steel.I-beam is divided into ordinary I-beam and light I-beam.So what are the specifications of I-beam?The following small make up for you to introduce：
I-beam is divided into ordinary I-beam, light I-beam and wide flange I-beam.According to the flange and the web height ratio is divided into wide, medium, narrow width flange I-beam.The former two steel specifications for the production of 10 ~ 60, that the corresponding height of 10cm ~ 60cm.At the same height, light I-beams have narrow flanges, thin webs, and light weight.Wide flange I-beam, also known as H-beam, cross-section is characterized by two parallel legs, and the inside of the leg no slope.It belongs to the economic section steel, is in the four-roll universal rolling mill, it is also known as”universal I-beam."Ordinary I-beam, light I-beam has become a national standard.
I-beam specifications in high×leg thick × waist thick, can also be used to indicate the main size of the number of specifications.Such as the 18th I-Beam, said the height of 18 cm I-beam.If the height of the same I-beam, you can fill in the number behind the angle Code A or b or c to be represented, such as 36a, 36b, 36c and so on.It is divided into ordinary I-beam, light I-beam and wide flange I-beam.According to the flange and the web height ratio is divided into wide, medium, narrow width flange I-beam.The first two specifications for the production of No. 10-60, that the corresponding height of 10cm-60cm.
After reading the introduction of small series, it is not to understand the specifications of the word steel model?For more information, please continue to pay attention to our website!
