◉Uma kuziwa ezinhlelweni zokuphatha amakhebula,amathreyi ekhebulaziyingxenye ebalulekile yokuhlela nokusekela izintambo ezindaweni ezihlukahlukene. Izinhlobo ezimbili ezidumile zethreyi lekhebula ziyiithreyi yekhebula elishisayo idiphukanye nethreyi lekhebula elilinganiselwe umlilo. Nakuba zombili zisetshenziselwa ukuphathwa kwekhebula, kunomehluko ohlukile phakathi kwakho kokubili.
◉Ithreyi lekhebula elinothayela elishisayo elidiphu elishisayo lidizayinelwe ukuhlinzeka ngenamathela evikelayo ensimbi, iyenze imelane nokugqwala futhi ifaneleke kokubili ukusetshenziswa ngaphandle nasendlini. Inqubo ye-hot-dip galvanizing ihlanganisa ukucwilisa amathreyi ekhebula lensimbi ku-zinc encibilikisiwe, ukudala ukunamathela okuqinile futhi okuhlala isikhathi eside okungamelana nezimo zemvelo ezinzima. Lolu hlobo lwethreyi yekhebula luvame ukusetshenziswa ezinhlelweni zezimboni nezohwebo lapho ukumelana nokugqwala kubaluleke kakhulu.
Ukumelana nomliloamathreyi ekhebula, ngakolunye uhlangothi, zenzelwe ngokukhethekile ukumelana nokushisa okuphezulu nokuvimbela ukusabalala komlilo uma kwenzeka ukuhluleka kwekhebula. Lawa mathreyi ekhebula enziwe ngezinto ezihlolwayo futhi ezigunyazwe ukuthi zihambisane nezindinganiso zokuphepha emlilweni. Amathreyi ekhebula angashi ngokuvamile asetshenziswa ezakhiweni lapho ukuvikela umlilo kuyinkinga enkulu, njengezibhedlela, izikhungo zedatha nezakhiwo eziphakeme.
◉Umehluko omkhulu phakathi kwethreyi lekhebula elinothayela elishisayo elishisayo kanye nethreyi lekhebula elilinganiselwe umlilo ukusetshenziswa kwalo okuhlosiwe kanye nezinto ezisetshenziswa ekwakhiweni kwalo. Amathreyi ekhebula anothayela ashisayo agxila ekuqineni kokugqwala, kuyilapho amathreyi ekhebula angashi abeka phambili ukuvikela umlilo. Kubalulekile ukukhetha uhlobo olufanele lwethreyi yekhebula ngokusekelwe ezidingweni ezithile zendawo yokufaka.
Kafushane, amathreyi ekhebula anamanzi ashisayo afaneleka ezinhlelweni ezidinga ukumelana nokugqwala, kuyilapho amathreyi ekhebula angashi aklanyelwe ukuhlinzeka ngokuvikelwa komlilo kwingqalasizinda ebalulekile. Ukuqonda umehluko phakathi kwalezi zinhlobo ezimbili zamathreyi ekhebula kubalulekile ekuqinisekiseni ukuphepha nokuthembeka kwezinhlelo zokuphatha ikhebula ezindaweni ezihlukahlukene. Ngokukhetha ithreyi lekhebula elifanele lomsebenzi, ungaphatha ngempumelelo izintambo ngenkathi ukhuluma ngezinto ezithile ezithinta imvelo nokuphepha.
