Black Iron vs Galvanized Pipe: Smart, Practical Choice

Summary for black iron vs galvanized pipe Discussion

Black iron vs galvanized pipe is the key choice for fire exit handrails in this thread. Kevin Roxas asked which pipe is more practical to use, and the answer focused on corrosion resistance versus paintability. The reply explained that black iron (plain steel) pipe has no inherent corrosion resistance, while galvanized pipe does. However, galvanized pipe can be difficult to field paint, whereas black pipe is relatively easy to paint. The practical recommendation was conditional: if the handrails will receive a good painted finish, black pipe is the better choice; if they will not be painted, galvanized pipe is the better option. The discussion did not mention code requirements or structural differences, only the tradeoff between durability and finishing convenience.
