I-beam ikakhulu yahlulwe eqhelekileyo I-beam, ukukhanya I-beam kunye flange ububanzi I-beam.Ngokomlinganiselo wobude be-flange kwiwebhu, yahlulwe ibe yi-I-beams ebanzi, ephakathi kunye nemxinwa ye-flange.Iimpawu ezimbini zokuqala ziyi-10-60, oko kukuthi, ukuphakama okuhambelanayo ngu-10 cm-60 cm.Ekuphakameni okufanayo, ukukhanya kwe-I-beam kune-flange encinci, iwebhu encinci kunye nobunzima obulula.I-wide flange I-beam, eyaziwa ngokuba yi-H-beam, ibonakala ngemilenze emibini ehambelanayo kwaye akukho tyekelo kwicala langaphakathi lemilenze.Iyinxalenye yentsimbi yecandelo loqoqosho kwaye iqengqeleke kwimill emine ephezulu yendalo yonke, ngoko ikwabizwa ngokuba yi "universal I-beam".I-I-beam eqhelekileyo kunye ne-I-beam yokukhanya yenze imigangatho kazwelonke.
