1. Galvanized
A na-ekewa plasta zinc ka ọ bụrụ electro-galvanized (oyi plating) na galvanizing na-ekpo ọkụ. A na-eji ihe nkiri zinc carbonate na-emepụta ihe na-emepụta n'elu zinc iji nweta nzube nke mgbochi nchara, mgbochi-erosion na ọdịdị mara mma. Electroplating zinc na-eji ụkpụrụ nke electrolysis mee ka ion zinc na-arapara n'elu ntupu ígwè iji mepụta mkpuchi. Cyanide dị na galvanizing electrolyte na-egbu egbu nke ukwuu. Ihe e ji mara electroplating bụ na oyi akwa zinc dị mma na kọmpat, na gloss dị ike. Galvanizing na-ekpo ọkụ na-ekpo ọkụ bụ itinye ihe a ga-etinye n'ime ihe ngwọta nke zinc maka ikpo ọkụ na-ekpo ọkụ na-ekpo ọkụ na-ekpo ọkụ mgbe mgbochi oxidation, annealing na ọgwụgwọ ndị ọzọ. Uru nke galvanizing na-ekpo ọkụ na-ekpo ọkụ bụ na a na-ekpuchi oyi akwa zinc nke ọma, ịdịte aka siri ike, na ndụ ọrụ nke afọ 20-50 nwere ike ịnọgide na-enwe. Ọnụ ahịa eletrọ-galvanized dị elu dị elu.
