Which statement correctly describes Galvanized Steel Pipe?

• A. It's a plastic pipe
• B. It's hot-dipped zinc-coated pipe for fire protection
• C. It's not suitable for sprinkler systems
• D. Used only for nonmetallic piping

Answer: (B)

Galvanized steel pipe is made of steel that has been coated with zinc, typically by hot-dip galvanizing, to protect the steel from rust and corrosion. This zinc coating acts as a sacrificial barrier, extending the pipe’s life in moist or damp environments, which is why galvanized steel is a common choice for fire sprinkler piping in many installations. That’s why the statement describing it as hot-dipped zinc-coated pipe for fire protection is the best fit. The other options miss the fundamentals: it isn’t plastic, galvanized steel is indeed used in sprinkler systems, and it isn’t restricted to nonmetallic piping.
