Iron is galvanized by several different processes. The zinc can be painted, if desired, or left plain. Thus, for nearly all outdoor uses a galvanized pipe is usually preferred to other plastic pipes such as PVC or ABS pipes. Chilled cast iron consists two layers of which one layer has white cast iron properties and other one has grey cast iron properties. Results of the tests showed measured differences between galvanized steel and steel that was not galvanized were very small and most likely attributable to microstructure heterogeneity. The spangle finish on the surface makes it visually appealing, but also makes it more durable and corrosion resistant. Once corrosion starts, it can spread under the zinc, eventually causing the metal to fail. Galvanized pipes are usually made up of iron or steel and therefore they are a bit heavy to handle. The zinc coating slows the process of corrosion and can make the pipe last for decades (in the right environment). The term is derived from the name of Italian scientist Luigi Galvani. Steel is unquestionably stronger than iron. A lot of this is in haemoglobin, in the blood. The addition of alloys changes the properties of steels. However, even galvanized pipes have their own advantages and disadvantages which you should consider before using them.
