Compare the cost of galvanizing to other corrosion protection systems
The estimated annual cost of corrosion is a staggering 3% of the US GDP and the life-cycle cost of corrosion maintenance for any one project is two to five times the initial cost, making the selection of a corrosion protection system for your project critical. However, too often the only cost analysis performed at the inception of a project is initial cost. The Life-Cycle Cost Calculator (LCCC) uses your specific imputed project data to develop and compare the initial and total cost (initial + maintenance) of over 30 steel corrosion protection systems (paint, metallizing) to hot-dip galvanizing.
Once you launch the calculator, you will be prompted to enter specific details about your project such as the total tonnage or surface area, coating type, surface preparation required, atmospheric exposure condition (rural, industrial, coastal), and desired service life. The LCCC will then run a complex calculation based on established financial industry equations to determine the value of money over time including net present value (NPV) and net future value (NFV). The LCCC automates the exact equations from the recently released specification ASTM A 1068, Practice for Life-Cycle Cost Analysis of Corrosion Protection Systems on Iron and Steel Products.
After you complete the three quick input screens with project details, the Life-Cycle Cost Calculator will generate a customized, printable report detailing the initial and life-cycle cost of hot-dip galvanizing compared to the system you selected.
KTA Tator, Inc., a consultant to the paint industry, conducts a survey of paint manufacturers biennially. The current data is based on the results of the 2008 survey which were published in Paper No. 8270 Expected Service Life and Cost Considerations for Maintenance and New Construction Protective Coating Work (Helsel, Lanterman, Wissmar), presented at the 2009 National Association of Corrosion Engineering (NACE) conference. Durability data, i.e. time to maintenance and time to full repaint in the paper is based on actual in-field performance.
Data for hot-dip galvanizing costs is based on a 2009 national survey conducted by the American Galvanizers Association (AGA) and durability data is based on field performance as well as models developed using statistical methods, neural network technology and an extensive worldwide corrosion database.
All equations are based on established financial industry equations and identical to those found in the ASTM A 1068 specification.
