Galv coating thickness
WebCoating thickness is an important requirement in the specification and effectiveness of hot-dip galvanizing as a corrosion protection system. However, measuring coating thickness is only one of the many specification requirements in the inspection process. Other key requirements include adherence, appearance, and finish. WebZinc coating thickness on galvanized sheet has a linear relationship to service life and for building interior service, coating grade G-60, which has two-thirds the life expectancy of G-90, is consistent with anticipated building service life of 30 years. Base metal thickness is reduced as zinc coating is increased.
