Black Phosphate will develop less white and red rust when compared to Bonderized steel that's installed in an exposed application and without any paint.
There is a coating that's applied on top of the galvanized substrate that's called InterCoat ChemGuard. This coating is designed to enhance the zinc performance on galvanized steel. We've done testing that will show the difference between the two.
How Much Does It Cost?
Cost about the same as Bonderized steel
About 20% less expensive than Kynar® painted panels
Better durability and will develop less white and red rust versus Bonderized
Less color variation versus Bonderized
Better cut edge protection
Beautiful black zinc appearance
Black Phosphate® is NOT a paint lock material that's designed to be post painted
Once mainly used in country style homes and buildings, this style has now seen a renewed use in large scale architectural projects. Metal board and batten is the perfect fit for both commercial and residential projects.
