A hanya domin zafi-tsoma galvanized karfe takardar da aka nutsa cikin zurfin zubi tutiya, wanda ake gyarawa da shafi kauri, sakamakon wani galvanized karfe sheet. Termodiffuzny Hanyar da ake amfani da kayayyakin da ciwon wani hadadden siffar, don sassaka da. Lokacin da galvanizing, tutiya contours daga cikin samfurin. A electrolytic hanya, tsoma galvanized shafi Layer daukan wuri ta wajen electrically conductive rollers. Wasu masu amfani kira shi da cathode wajen. Lokacin da aka tuhuma da wani karfe sashi a cikin wani wanka dauke da gishiri bayani ne sai sun shige ta da shi da lantarki.
