Gusya ibyuma bifite ibyiza byo kuzigama ibyuma, kurwanya ruswa, kubaka byihuse, byiza kandi byiza, kutanyerera, guhumeka, nta mwobo, nta kwegeranya amazi, kutagira ivumbi, nta kubungabunga, hamwe nubuzima bwa serivisi bwimyaka irenga 30. Iragenda ikoreshwa cyane ninzego zubaka. Ubuso bwa gritingi yicyuma buravurwa, kandi nyuma yubuvuzi bwihariye bushobora kuramba. Imikoreshereze yimashini yicyuma munganda zinganda usanga zifunguye cyane cyangwa ahantu hamwe na ruswa yangirika. Kubwibyo, kuvura hejuru yicyuma gifite akamaro kanini mubuzima bwa serivisi yo gusya ibyuma. Ibikurikira bitangiza uburyo busanzwe bwo kuvura ibyuma.
. Ubunini bwurwego rwa zinc ntibushobora kuba munsi ya 65um kubisahani bito munsi ya 5mm, kandi ntibiri munsi ya 86um kubisahani. Gutyo, gushikira intumbero yo gukumira ruswa. Ibyiza byubu buryo ni birebire birebire, urwego rwo hejuru rwinganda zinganda, nubwiza buhamye. Kubwibyo, ikoreshwa cyane mubikorwa byo gusya ibyuma byo hanze byangirika cyane nikirere kandi bigoye kubungabunga. Intambwe yambere yo gushyushya-gusya ni ugutoragura no gukuramo ingese, hagakurikiraho gusukura. Kutuzuza izi ntambwe zombi bizasiga akaga kihishe kurinda ruswa. Kubwibyo, bigomba gukemurwa neza.
. Uburyo bwihariye ni ukubanza gutobora umusenyi hejuru yicyuma kugirango ukureho ingese, kugirango ubuso bugaragaze urumuri rwinshi na roughens. Noneho koresha urumuri rwa acetylene-ogisijeni kugirango ushongeshe insinga ya aluminiyumu (zinc) idahwema gutangwa, hanyuma uyitere hejuru yicyuma gisya hamwe numwuka uhumanye kugirango ube ubuki bwa aluminium (zinc) butera (uburebure bwa 80um ~ 100um). Hanyuma, uzuza capillaries hamwe na coatings nka cyclopentane resin cyangwa urethane rubber irangi kugirango ube umwenda. Ibyiza byiyi nzira nuko ifite imiterere ihindagurika cyane yubunini bwicyuma, kandi imiterere nubunini bwa feri yicyuma ntikibujijwe. Iyindi nyungu nuko ingaruka ziterwa nubushyuhe bwiki gikorwa ari izibanze kandi zirakumirwa, ntabwo rero bizatera ihinduka ryubushyuhe. Ugereranije na hot-dip galvanizing yo gusya ibyuma, ubu buryo bufite urwego rwo hasi rwinganda, kandi imbaraga zumurimo wo guturika umucanga na aluminium (zinc) ni nyinshi. Ubwiza nabwo bugira ingaruka byoroshye kumihindagurikire yimikorere.
. Ifite igiciro gito cyigihe kimwe, ariko ikiguzi cyo kubungabunga ni kinini iyo ikoreshejwe hanze. Intambwe yambere yuburyo bwo gutwikira ni ugukuraho ingese. Impuzu zo mu rwego rwo hejuru zishingiye ku gukuraho ingese. Kubwibyo, ibyangombwa bisabwa cyane muri rusange bifashisha umucanga no guturika kugirango ukureho ingese, ugaragaze urumuri rwicyuma, kandi ukureho ingese zose hamwe namavuta. Guhitamo gutwikira bigomba kuzirikana ibidukikije. Imyenda itandukanye ifite kwihanganira ibintu bitandukanye. Ubusanzwe impuzu zigabanijwemo primers (layers) na topcoats (layers). Primers irimo ifu nyinshi nibikoresho bike fatizo. Filime irakomeye, ifatanye cyane nicyuma, kandi ifitanye isano nziza namakoti. Topcoats ifite ibikoresho fatizo byinshi, ifite firime zirabagirana, irashobora kurinda primers kwangirika kwikirere, kandi irashobora kurwanya ikirere. Hano hari ikibazo cyo guhuza hagati yimyenda itandukanye. Mugihe uhisemo imyenda itandukanye mbere na nyuma, witondere guhuza kwabo. Ubwubatsi bwa coating bugomba kugira ubushyuhe bukwiye (hagati ya 5 ~ 38 ℃) nubushuhe (ubushuhe bugereranije ntiburenze 85%). Ibidukikije byubatswe bigomba kuba bituzuye ivumbi kandi ntihakagombye kubaho ubukonje hejuru yikintu. Ntigomba guhura nimvura mugihe cyamasaha 4 nyuma yo gutwikira. Igifuniko gikoreshwa inshuro 4 ~ 5. Ubunini bwuzuye bwa firime yumye yumye ni 150um kumishinga yo hanze na 125um kumishinga yo murugo, hamwe no gutandukana 25um.
