The Bonderized steel should be painted immediately after installing to prevent the phosphate coating from developing white rust. The galvanized steel is first cleaned and rinsed and then has a conditioning agent applied to form a fine crystalline zinc phosphate coating. By doing this, the process turns the bare galvanized surface to an inert, crystalline zinc phosphate which then is rinsed and sealed with a dried chromate coating. Bonderized steel is popular in the rainwater goods industry. Typical uses are, rain gutters, downspouts, roof flashings, and roof valleys. This zinc phosphate finish is a perfect surface for painting of the fabricated material in the field.
