I-Galvanized Steel Electrical Metallic Tubing (EMT) yeyona ndlela yombane egqwesileyo enokusetyenziswa ngoku ekhoyo kwindawo yentengiso.

I-EMT yenziwe ngentsimbi ephezulu, kwaye iveliswe yinkqubo yokumelana nombane.

Ingaphakathi kunye nomphandle we-EMT ukhululekile kwisiphene kunye ne-welded seam egudileyo, kwaye ifakwe ngokucokisekileyo kwaye ifakwe ngokulinganayo nge-zinc kusetyenziswa inkqubo ye-galvanizing yediphu eshushu, ukwenzela ukuba uqhagamshelwano lwetsimbi ukuya kwintsimbi kunye nokukhuselwa kwegalvanic ngokuchasene nokuhlwa kubonelelwe.

Umphezulu we-EMT kunye ne-post-galvanizing coating ecacileyo ukubonelela ngokhuseleko olongezelelweyo kwi-corrosion. Umphezulu wangaphakathi ubonelela ngomdyarho ogudileyo oqhubekayo wokutsalwa ngocingo lula. Umbhobho wethu we-EMT une-ductility egqwesileyo, ukubonelela ngokugoba okufanayo, ukusika kwintsimi.

I-EMT iveliswa ngokobukhulu obuqhelekileyo borhwebo ukusuka ? ukuya ku4”. I-EMT iveliswa kubude obuqhelekileyo be-10 '(3.05 m). Ubungakanani kwi-bundle kunye ne-master bundle bunjengoko kuluhlu olungezantsi. Iinyanda ze-EMT ezigqityiweyo zichongwa ngeteyiphu enekhowudi yombala ukuze kuchongwe ubungakanani obulula.
