Mapaipi opangidwa ndi galvanized otentha amapangidwa ndi chitoliro chachitsulo cha kaboni komanso ndi zinc. Njirayi imaphatikizapo kutsuka chitoliro chachitsulo kuti achotse dzimbiri kapena okosijeni, kuyeretsa ndi yankho la ammonium chloride, zinc chloride, kapena kuphatikiza zonse ziwiri musanaziike mu bafa losambira lotentha. Chophimbacho chimakhala chofanana, chomatira kwambiri, ndipo chimalimbana kwambiri ndi dzimbiri chifukwa cha zovuta zakuthupi ndi zamankhwala zomwe zimachitika pakati pa chitsulo ndi zinc yosungunuka. Chigawo cha alloy chimalumikizana ndi zinc wosanjikiza woyera ndi chitoliro chachitsulo, zomwe zimapangitsa kuti chisawonongeke kwambiri.
Mapaipi opangidwa ndi ma galvanized otentha amagwiritsidwa ntchito kwambiri m'magawo osiyanasiyana monga m'nyumba zosungiramo zomera, zoteteza moto, zoperekera mpweya, ndi njira zotulutsira madzi.
