Galvanized Steel Electric Metallic Tubing (EMT) bụ ezigbo ọkụ eletrik iji jiri ugbu a n'ahịa.

A na-eji ígwè dị elu arụ ọrụ EMT, ma na-emepụta ya site na usoro ịgbado ọkụ eletrik.

Ime na mputa elu nke EMT enweghị ntụpọ na ezigbo welded onuete, na-juju na evenly ntekwasa na zinc na-eji ọkụ itinye galvanizing usoro, nke mere na metal-na-metal kọntaktị na galvanic nchebe megide corrosion na-nyere.

N'elu EMT na mkpuchi post-galvanizing doro anya iji nyekwuo nchebe megide corrosion. Ime elu dị n'ime na-enye ụzọ ịgba ọsọ na-aga nke ọma maka ịdọrọ waya dị mfe. Anyị EMT conduit nwere ọmarịcha ductility, na-enye maka ekwe ekwe, ịkpụ n'ubi.
