Isakhiwo sensimbi siyisisindo esilula, amandla aphezulu, ukusebenza kahle kokuzamazama komhlaba, ukonga amandla, kungenziwa kabusha isakhiwo sokwakha.Ukwakha imikhiqizo yensimbi ekhethekile, okuhlanganisa izinga eliphezulu lensimbi yesakhiwo eshiselwe, ipuleti lekhwalithi ephezulu yamandla, ipayipi le-thermoformed, insimbi nokunye ukuthengiswa okuphezulu;nwebisa insimbi eyakhiwe ngendlela ebandayo kanye nezinhlobo ze-H-beam ezigingqiwe ezishisayo kanye nezici, kuhlanganise nengxenye enkulu yamapayipi akhiwe ngendlela ebandayo enkulu ye-cross-section H-beam kanye ne-H-beam ekhanyayo, njll;ukukhuthazwa okunengqondo kokusetshenziswa kwensimbi yesimo sezulu, insimbi ye-refractory, i-Z kuya kwensimbi kanye nama-electrode anezintambo nokunye.Inzuzo enkulu yikhono Izakhiwo zesakhiwo sensimbi zidinga ukuthi abantu basebenze, izidingo zezinzwa, kanye nezidingo zomnotho ndawonye ngokuphelele.Isakhiwo sensimbi esisebenza kahle kakhulu eminyakeni yamuva, ukuthuthukiswa kwesicelo esisheshayo, ububanzi bezicelo buhlanganisa cishe zonke izindawo zesakhiwo, kuhlanganise nokwakhiwa kwezindlu, amabhuloho, amadamu, amapulatifomu asogwini nezinye izakhiwo kanye ne-tower mast.

Isakhiwo sensimbi esisetshenziswa njengamanje kuphrojekthi singaba yisimo esiphambene, isakhiwo kanye nezindlela zokukhiqiza zokuhlukanisa.Cindezela-isigaba, isakhiwo sensimbi singahlukaniswa sibe isakhiwo se-tube (CHS), isakhiwo se-tube esinezikwele (rectangular) (RHS) nezinye izigaba zomumo.Ngenxa yokuphakama mayelana nokubukeka nokusebenza komshini, ukusetshenziswa kwesakhiwo sepayipi kanye nesakhiwo se-tube yesikwele esisetshenziswa kakhulu kunazo zonke.Ngokusho kwesakhiwo ngendlela yamaphuzu, isakhiwo sensimbi singahlukaniswa sibe yigridi (igobolondo lenetha), ama-trusses, amafreyimu kanye nesakhiwo sekhonkrithi yepayipi yensimbi yezine.Isakhiwo sensimbi sibhekisela ekusetshenzisweni njengendlela yeshubhu kanye neshubhu yesikwele phakathi kwezingxenye, amapayipi namashubhu axhunywe ngama-weld ahlukanisayo.Ngokusho izindlela zokukhiqiza ukuze amaphuzu, isakhiwo steel ingahlukaniswa hot-iphuma steel isakhiwo, abandayo-roll roll steel tube isakhiwo, ashiselwe steel ipayipi isakhiwo ezintathu.Ipayipi lensimbi eligoqiwe elishisayo liwugqinsi, izindleko zokukhiqiza eziphezulu, ukushuba kwepayipi lensimbi eligoqiwe kubanda kuncane.
