◉Uma kukhulunywa ngezinhlelo zokuphatha izintambo,amathreyi ekhebulaziyisici esibalulekile sokuhlela nokusekela izintambo ezindaweni ezahlukahlukene. Izinhlobo ezimbili ezidumile zethreyi yekhebula yileziithreyi yekhebula elishisayo elihlanganisiwekanye nethreyi yekhebula elilinganiselwe umlilo. Nakuba zombili zisetshenziselwa ukuphathwa kwekhebula, kunemehluko ocacile phakathi kwazo zombili.
◉Ithreyi yekhebula elihlanganisiwe elishiswa ngokushisa yenzelwe ukuhlinzeka ngendwangu evikelayo ensimbini, okwenza imelane nokugqwala futhi ifanele ukusetshenziswa ngaphandle nangaphakathi. Inqubo ye-hot-dip galvanizing ihilela ukucwilisa amathreyi ekhebula lensimbi ku-zinc encibilikisiwe, okudala ingubo eqinile nehlala isikhathi eside engamelana nezimo zemvelo ezinzima. Lolu hlobo lwethreyi yekhebula luvame ukusetshenziswa ezisetshenziswayo zezimboni nezentengiselwano lapho ukumelana nokugqwala kuyinto eza kuqala.
Ayishisiamathreyi ekhebulaNgakolunye uhlangothi, zenzelwe ngqo ukumelana namazinga okushisa aphezulu nokuvimbela ukusabalala komlilo uma kwenzeka ikhebula lihluleka. Lawa matreyi ekhebula enziwe ngezinto ezivivinywe futhi eziqinisekisiwe ukuthi ziyahambisana nezindinganiso zokuphepha emlilweni. Amatreyi ekhebula angashisi umlilo avame ukusetshenziswa ezakhiweni lapho ukuvikelwa komlilo kuyinkinga enkulu, njengezibhedlela, izikhungo zedatha kanye nezakhiwo eziphakeme.
◉Umehluko omkhulu phakathi kwethreyi yekhebula elihlanganisiwe elishisayo kanye nethreyi yekhebula elilinganiselwe umlilo ukusetshenziswa kwayo okuhlosiwe kanye nezinto ezisetshenziswa ekwakhiweni kwayo. Amathreyi ekhebula elihlanganisiwe elishisayo agxile ekumelaneni nokugqwala, kuyilapho amathreyi ekhebula angashisi umlilo ebeka phambili ukuvikelwa komlilo. Kubalulekile ukukhetha uhlobo olufanele lwethreyi yekhebula ngokusekelwe ezidingweni ezithile zendawo yokufaka.
Ngamafuphi, amathreyi ekhebula acwebezelayo ashisayo afaneleka kakhulu ezinhlelweni zokusebenza ezidinga ukumelana nokugqwala, kuyilapho amathreyi ekhebula angashisi eklanyelwe ukuhlinzeka ngokuvikelwa komlilo kwengqalasizinda ebalulekile. Ukuqonda umehluko phakathi kwalezi zinhlobo ezimbili zamathreyi ekhebula kubalulekile ekuqinisekiseni ukuphepha nokuthembeka kwezinhlelo zokuphatha ikhebula ezindaweni ezahlukahlukene. Ngokukhetha ithreyi yekhebula efanele umsebenzi, ungaphatha izintambo ngempumelelo ngenkathi ubhekana nezinkinga ezithile zemvelo nokuphepha.
