Galvanized Steel is relatively inexpensive compared to other options and is very robust with a long life for pneumatic applications.
The coating of galvanized steel aids in preventing rust from occurring allowing for a clean fluid to be consistently supplied. Equally, the material properties allows for a wide range of suitable pressure and temperature applications.
Despite the low unit cost and excellent suitability to most applications, labor costs are greater than some lightweight counterparts. This is due to the weight of the material making it difficult to work with. The difficulties are primarily in situations where the pipework system is located in high locations.
