IEC STANDARD EMT CONDUIT COUPLINGS AND CONNECTOR - STEEL
STEEL
IEC Standard EMT Conduit Couplings and Connectors – Steel
When choosing EMT conduit fittings, zinc die-cast products are widely used because of their strong resistance to rust and corrosion. They perform well in many environments and are a popular choice for general electrical installations.
However, for indoor projects or dry environments, steel EMT couplings and connectors are often the better option. Steel fittings provide significantly higher mechanical strength compared with zinc die-cast. This means:
If the conduit system is exposed to impact or heavy load,
If tools or equipment accidentally hit the fittings,
Or if the installation requires stronger structural support,
steel fittings will withstand force much better than zinc.
In demanding conditions where durability and strength matter more than corrosion resistance, IEC-standard steel EMT fittings deliver safer, longer-lasting performance.
