Iphrofayili yayo emise okwe-I iqukethe ama-flange amabili avundlile axhunywe iwebhu eqondile, eletha ukusebenza okuhle kakhulu komthwalo ngenkathi kugcinwa ukusetshenziswa okusebenzayo kwezinto. Itholakala ngamamaki ensimbi ahlukahlukene, ubukhulu, ukujiya, nobude, ingabuye yenziwe ngezifiso ngokusika, ukubhoboza, ukushisela, ukupenda, noma izinsiza zokugalela. Insimbi ye-I beam isetshenziswa kakhulu ekwakheni amafreyimu, amasistimu aphansi, amabhuloho, izinkundla zemishini, izitshalo zezimboni, izindawo zokugcina izimpahla, kanye nezakhiwo zokusekela imishini.
