Hot-ina tlotsa metale ka senke ke ho qhibilihisa zinki ka boemo mokelikeli, 'me joale qoelisa substrate ho tlotsitsoe, e le hore zinki theha lera e kenang le substrate ho tlotsitsoe, e le hore tlamo e thata haholo,' me ha ho litšila kapa Liphoso li lula bohareng ba lera, 'me botenya ba seaparo bo boholo, bo ka fihla ho 100um, ka hona, ho hanyetsa kutu ho phahameng, tlhahlobo ea letsoai e ka fihla lihora tse 96, e leng lilemo tse 10 tikolohong e tloaelehileng; ha galvanizing e batang e etsoa ka mocheso o tloaelehileng, leha botenya ba seaparo bo ka laoloa, empa bo lekane Mabapi le matla a botenya le botenya, ho hanyetsa ts'enyeho ho hobe. Phapang e ka sehloohong lipakeng tsa mefuta e 'meli ea terata e sirelelitsoeng ke tse latelang:
(1) Ho tloha holimo, chesang-ina galvanized welded terata letlooeng ha e khanyang le chitja joaloka batang-galvanized welded terata letlooeng.
(2) Ho tloha ka bongata ba zinki, mochini o chesang o chesang o chesang o chesang o na le zinki e phahameng ho feta terata e batang e batang.
(3) Ho tloha ponong ea bophelo ba ts'ebeletso, terata e chesang e kenang e chesang e chesang e na le bophelo bo bolelele ba ts'ebeletso ho feta terata ea elektrone e hahiloeng ka terata.
