Galvanized Steel Electrical Metallic Tubing (EMT) ndi ngalande yamagetsi yabwino kwambiri yomwe ikupezeka pamsika.

EMT imapangidwa ndi chitsulo champhamvu kwambiri, ndipo imapangidwa ndi njira yowotcherera yamagetsi.

Mkati ndi kunja kwa EMT kulibe chilema ndi msoko wofewa wofewa, ndipo amakutidwa bwino ndi zinki pogwiritsa ntchito njira yotenthetsera ya dip dip, kotero kuti kukhudzana ndi chitsulo ndi chitsulo ndi chitetezo cha galvanic ku dzimbiri zimaperekedwa.

Pamwamba pa EMT yokhala ndi zokutira zomveka bwino pambuyo pa malata kuti apereke chitetezo china ku dzimbiri. Mkati pamwamba amapereka yosalala mosalekeza mpikisano wosavuta kukoka waya. Njira yathu ya EMT ili ndi ductility yabwino kwambiri, yoperekera kupindika yunifolomu, kudula m'munda.

EMT imapangidwa mumayendedwe abwinobwino kuchokera ku ? " ku 4”. EMT imapangidwa muutali wokhazikika wa 10' (3.05 m). Kuchuluka kwa mtolo ndi master bundle ndi monga pa tebulo ili m'munsimu. Mitolo ya EMT yomalizidwa imadziwika ndi tepi yamitundu kuti izindikirike mosavuta.

Mbali ndi Ubwino

Zofotokozera:
