The zinc bonds with the iron to form a protective layer that prevents rust and corrosion. Hot-dip galvanized pipes have a wide range of applications, from residential to industrial. They come in various shapes and sizes and can be used for new construction as well as repairs. If properly maintained, hot-dip galvanized pipes can last for decades, making them a cost-effective choice for homeowners and businesses alike. Pre Galvanized Steel Tubes Pre-galvanized pipe is a type of steel pipe that has been coated with a zinc-based metal layer before manufacturing. The steel pipe is roll-formed, welded if necessary, and then shaped into the desired form through a set of high-speed rollers. The zinc coating provides excellent corrosion resistance to the base metal, making this type of pipe commonly used in construction and other applications requiring durable surface treatment. However, due to the manufacturing method, the weld seam inside the pipe cannot be coated with zinc spray, so rusting may still occur in that area.
