Are galvanized products guaranteed for minimum results in a salt-spray test?
No, due to the inherent variances in the production of the product. In general, the more zinc on the surface, the greater number of hours can be expected prior to the formation of red rust in a salt spray test. (Laboratory test data is available upon request.) Additionally, although salt spray testing procedures are available as a specification, there are inconsistencies in the test apparatus so as to make the results non-reproducible. If the customer requires extra corrosion protection above and beyond that of the regular galvanize coatings of G90 and G60, while maintaining good surface characteristics, Weirkote Plus Galfan can be ordered.
