Kuti mupewe kupangika kwa banga lonyowa m'malo osungira, chonde tsatirani malangizo awa:
1. Musamange zinthu zatsopano zomatira pamwamba pa zina, ndipo musazisunge pafupi kwambiri
2. Sungani mkati ngati n'kotheka, kutali ndi pansi komanso pamalo otsetsereka
3. Onetsetsani kuti pali mpweya wokwanira woyenda bwino m'malo osungiramo zinthu
4. Chotsani pulasitiki kapena phukusi lakanthawi kuchokera ku zinthu zopangidwa ndi galvanized zikangonyamulidwa, chifukwa phukusi limatha kusunga kapena kusunga chinyezi mkati.
5. Madontho osungira zinthu zonyowa pamalo opangidwa ndi galvanized akhoza kutsukidwa, komabe, njirayi ndi yosiyana pang'ono kutengera kuopsa kwa banga. Pokhapokha ngati kuyeretsa kukufunika pazifukwa zokongola, madontho osungira zinthu zonyowa pang'ono komanso pang'ono akhoza kuonekera pa mpweya wabwinobwino ndikusiyidwa kuti nyengo isinthe. Izi zithandiza kuti bangalo lisinthe kukhala zinc carbonate patina yoteteza. Ngati malo onyowa atsukidwa, kukula kwa patina kudzayambiranso koma, kudzabwezeretsa kukongola kulikonse koyambirira.
