◉Izitebhisi zekhebula le-aluminiumziyizingxenye ezibalulekile ekufakweni kukagesi, ezihlinzeka ngesixazululo esiqinile kodwa esingasindi sokusekelwa kwekhebula nokuhleleka. Kodwa-ke, ukuze kwandiswe impilo nokusebenza kwezitebhisi zekhebula, kubalulekile ukucabangela ukusebenzisa i-coating efanele kulawa masitebhisi.

◉Esinye sezizathu eziyinhloko zokugqoka iikhebula le-aluminiumisitebhisi esokuthuthukisa ukumelana nokugqwala. Nakuba i-aluminiyamu imelana nokugqwala ngokwemvelo, isengakwazi ukuhlushwa yi-oxidation lapho ibhekene nezimo zemvelo ezinzima. Ngakho-ke, ukusebenzisa i-coating yokuzivikela kungandisa kakhulu impilo yesitebhisi. Izembatho ezivamile zihlanganisa i-anodizing, i-powder coating, ne-epoxy coating.

◉I-Anodizing iyisinqumo esidumile sezitebhisi zekhebula le-aluminium. Le nqubo ye-electrochemical ishubisa ungqimba lwe-oxide yemvelo endaweni ye-aluminium, inikeze ukumelana nokugqwala okuhle kakhulu nokuqina. I-Aluminiyamu ye-anodized nayo inendawo ebukeka kahle, eyinzuzo enkulu kubuhle bokufakwa okubonakalayo.

◉I-powder coating ingenye inketho ephumelelayo. Inqubo ihilela ukusebenzisa impushana eyomile eselapheka emazingeni okushisa aphezulu ukuze yakhe ungqimba oluqinile, oluvikelayo. Ukufakwa kwempuphu akugcini nje ngokuthuthukisa ukumelana nokugqwala kweladi, kodwa futhi kutholakala ngemibala ehlukahlukene kanye nokuqedwa, okuvumela ukwenziwa ngokwezifiso ukuhlangabezana nezidingo ezithile zephrojekthi.

◉Izembatho ze-epoxy nazo zifanelekileizitebhisi zekhebula le-aluminium, ikakhulukazi ezindaweni lapho ukuchayeka kumakhemikhali kuwukukhathazeka. Lezi zimbotshana zinikeza umgoqo oqinile, omelana namakhemikhali ongamelana nezimo ezinzima, uzenze zilungele ukusetshenziswa kwezimboni.

◉Uma ukhetha ukumboza isitebhisi sekhebula le-aluminium, izimo ezithile zemvelo kanye nezidingo zokufakwa kufanele kucatshangelwe. I-anodizing, i-powder coating, kanye ne-epoxy coating yizo zonke izinketho ezisebenzayo ezingathuthukisa ukuqina nokusebenza kwezitebhisi zekhebula le-aluminium, kuqinisekiswe ukuthi zihlala ziyisinqumo esithembekile sokuphathwa kwekhebula ezindaweni ezihlukahlukene.
