Zinc Coated Pre-Galvanized Round Steel Pipe ASTM A0252 Cold Drawn Welded Galvanized Steel Tube For Construction
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. However, even the best-galvanized pipes will eventually lose their zinc coating due to erosion and the ravages of time and nature. Once that occurs, the raw steel is exposed to moisture and oxygen, and the rusting process commences. |
