u'amea ipu uamea o se uʻamea ipu uamea ma vevela-dip po o le electro galvanized coating i luga o le fogaeleele, lea e masani ona faʻaaogaina i le fausiaina, meafale, taavale ma vaʻa, gaosiga o koneteina, alamanuia electromechanical, ma isi.
O le atina'eina o le gaosiga o le galvanizing vevela i Saina ua tuai i tua.Mai le 1950s i le 1960s, 13 flux hot-dip galvanizing units mo ipu u'amea tasi laupepa na fausia faasolosolo, faatasi ai ma le gafatia o 100000 t / A. Ae ui i lea, ona o le faaletonu o le maualalo o le gaosiga, tau maualuga, leaga le lelei, faʻaleagaina o le siosiomaga, leaga. manuia tau tamaoaiga ma isi mea, ua taofia ma sui i le gaosiga.Mai le fa'ai'uga o le 1970s, na amata ai e Saina ona fau le tele-tele broadband hot-dip galvanizing units.
