Why is conduit galvanized?

Galvanizing conduit involves coating it with a layer of zinc through a process known as hot-dip galvanization. This zinc coating serves as a protective barrier against corrosion, which is particularly important for conduits installed in outdoor or damp environments where moisture and other corrosive elements can cause metal to rust and degrade over time. By protecting the metal surface from these harsh conditions, galvanized conduit significantly enhances the longevity and durability of the installation.

The other options do not accurately describe the primary purpose of galvanizing. While improved conductivity, flexibility, and reduced electrical resistance are important characteristics in electrical systems, they are not achieved through the galvanization process. Instead, galvanizing is specifically aimed at ensuring the physical integrity of the conduit against environmental elements.
