◉Xa kufikwa kwiinkqubo zolawulo lweentambo,iitreyi zekhebulazizinto ezibalulekileyo ekuhleleni nasekuxhaseni iintambo kwiindawo ezahlukeneyo. Iindidi ezimbini ezidumileyo zetreyi yentambo zeziitreyi yekhebula eshushu egalelweyokunye netreyi yekhebula elinganiswa ngumlilo. Nangona zombini zisetyenziselwa ulawulo lwekhebula, kukho umahluko omkhulu phakathi kwezi zimbini.
◉Itreyi yekhebula egqunyiweyo eshushu yenzelwe ukubonelela ngengubo ekhuselayo kwintsimbi, okwenza ukuba ingagqwali kwaye ifaneleke ukusetyenziswa ngaphandle nangaphakathi. Inkqubo ye-hot-dip galvanizing ibandakanya ukuntywila iitreyi zekhebula zentsimbi kwi-zinc enyibilikisiweyo, okwenza ingubo ehlala ixesha elide nehlala ixesha elide enokumelana neemeko ezinzima zokusingqongileyo. Olu hlobo lwetreyi yekhebula lusetyenziswa rhoqo kwizicelo zoshishino kunye nezorhwebo apho ukumelana nokugqwala kuyinto ephambili.
Ayitshisiiitreyi zekhebulaKwelinye icala, zenzelwe ngokukodwa ukumelana namaqondo obushushu aphezulu nokuthintela ukusasazeka komlilo xa kukho ukungasebenzi kakuhle kwentambo. Ezi treyi zentambo zenziwe ngezinto ezivavanyiweyo neziqinisekisiweyo ukuba ziyahambelana nemigangatho yokhuseleko lomlilo. Iitreyi zentambo ezingatshiyo zisetyenziswa rhoqo kwizakhiwo apho ukhuseleko lomlilo luyingxaki enkulu, njengezibhedlele, amaziko edatha kunye nezakhiwo eziphakamileyo.
◉Umahluko ophambili phakathi kwetreyi yekhebula egalelweyo eshushu kunye netreyi yekhebula elinganiswe ngomlilo yindlela esetyenziselwa ngayo kunye nezinto ezisetyenziswa ekwakhiweni kwayo. Iitreyi zekhebula ezigalelweyo ezishushu zigxila ekumelaneni nokugqwala, ngelixa iitreyi zekhebula ezinganyangekiyo ngomlilo zibeka phambili ukhuseleko lomlilo. Kubalulekile ukukhetha uhlobo olufanelekileyo lwetreyi yekhebula ngokusekelwe kwiimfuno ezithile zendawo yokufakela.
Ngamafutshane, iitreyi zekhebula ezifakwe kwi-hot-dip zilungele ukusetyenziswa okufuna ukumelana nokugqwala, ngelixa iitreyi zekhebula ezimelana nomlilo zenzelwe ukubonelela ngokhuseleko lomlilo kwiziseko ezibalulekileyo. Ukuqonda umahluko phakathi kwezi ntlobo zimbini zeetreyi zekhebula kubalulekile ekuqinisekiseni ukhuseleko kunye nokuthembeka kweenkqubo zolawulo lweentambo kwiindawo ezahlukeneyo. Ngokukhetha itreyi yekhebula efanelekileyo kulo msebenzi, unokulawula iintambo ngempumelelo ngelixa ujongana neengxaki ezithile zokusingqongileyo kunye nokhuseleko.
