Beth Yw Galfaneiddio?
Galfaneiddio yw'r broses o orchuddio dur â sinc tawdd i'w amddiffyn rhag cyrydiad. Mae sinc yn adweithio â'r amgylchedd i ffurfio ffilm sinc carbonad trwchus sy'n blocio ocsigen a lleithder, gan ymestyn oes y dur trwy5-10 gwaitho'i gymharu â dur noeth.
Mae cotio Z275 yn sicrhau trwch sinc digonol i wrthsefyll -amlygiad hirdymor i law, halen, cemegau ac ymbelydredd UV.
