Galvanized steel pipes are constructed from raw steel coated with a corrosion-resistant material. The coating process, known as galvanizing, involves the use of dipping steel into molten zinc. Pure zinc is an ideal material for galvanizing due to its abundance, low cost, and low toxicity to humans. Galvanized pipe is used in outdoor and indoor applications due to its anti-rusting components. The zinc coating slows the process of corrosion and can make the pipe last for decades (in the right environment).
