Galvanized Steel Pipe is described as what?

• A. Hot-dipped zinc-coated pipe for fire protection
• B. Stainless steel pipe
• C. Copper pipe
• D. Plastic pipe

Answer: (A)

Galvanized steel pipe is steel pipe that has a protective zinc coating applied by hot-dip galvanizing, where the pipe is dipped into molten zinc to form a durable layer. In fire protection terms, this is described as hot-dipped zinc-coated pipe for fire protection because the zinc coating resists corrosion in wet sprinkler service. It isn’t stainless steel, copper, or plastic, which are different materials with their own properties. Note that the zinc coating can be damaged during threading or cutting, which can expose steel to corrosion, so proper handling and finishing are important.
