Galvanized Steel Electrical Metallic Tubing (EMT) iwumzila kagesi omuhle kakhulu ongawusebenzisa otholakala emakethe.

I-EMT ikhiqizwa ngensimbi enamandla amakhulu, futhi ikhiqizwa inqubo yokushisela ukumelana nogesi.

Indawo yangaphakathi nengaphandle ye-EMT ayinaso isici esinomthungo oshiselwe obushelelezi, futhi imbozwe kahle futhi ngokulinganayo nge-zinc kusetshenziswa inqubo yokufaka idiphu eshisayo, ukuze kuthintwa kwensimbi kuya kwensimbi kanye nokuvikelwa kwe-galvanic ekugqwaleni kuhlinzekwe.

Ingaphezulu le-EMT elinoqweqwe olucacile lwangemva kokufaka uthayela ukuze linikeze ukuvikeleka okwengeziwe ekugqwaleni. Indawo engaphakathi ihlinzeka ngomgwaqo oqhubekayo oshelelayo wokudonsa izintambo kalula. I-EMT conduit yethu ine-ductility enhle kakhulu, ihlinzeka ngokugoba okufanayo, ukusika ensimini.

I-EMT ikhiqizwa ngosayizi abajwayelekile bokuhweba kusuka ku-? kuye 4”. I-EMT ikhiqizwa ngobude obujwayelekile obungu-10' (3.05 m). Inani ku-bundle kanye ne-master bundle linjengethebula ngalinye elingezansi. Izinqwaba ze-EMT eqediwe zikhonjwa ngetheyiphu enemibala ukuze kukhonjwe usayizi olula.
