If dipping or spraying, the solution temperature should be between 140 to 185 F / 60 to 85 C. For newly galvanized surfaces, a water-based emulsifier can be used to remove contaminants. After cleaning, thoroughly rinse the surface with clean, hot water and allow complete drying before profiling or painting.
4.1 This practice describes the methods of preparation of hot-dip galvanized surfaces prior to the application of powder coating. The key to achieving proper adhesion between powder coatings and galvanized steel is surface preparation. The surface must be entirely free from visible metal oxides prior to powder coating.(plate) Communicate with the galvanizer.

Advantages and disadvantages. Despite the large number of metal protection methods (galvanic, diffusion, gas dynamics, cold and hot galvanizing(plate) Duplex Systems for Corrosion American Galvanizers Preparing Hot Dip Galvanized Steel for Painting or Powder (steel) One of the most durable protective coatings for steel is provided by applying a polyester powder coating over hot dip galvanized steel to provide a high grade architectural finish to steel items. Hot dip galvanizing is coating of metallic zinc bonded with steel to form a source of corrosion protection for steel.(plate) Hot-dip galvanizing or painting?(steel) Painting steel without previously cleaning the surface is not a well done job, and the need to renew the coating occurs within less than three years. Hot-dip galvanization is cheaper and more permanent. The thinner the sheer, the cheaper hot-dip galvanization is in comparison with painting. For 9mm sheet, the costs of hot-dip galvanization Preparing Hot Dip Galvanized Steel for Painting or Powder
Part 4 covers types of surface and surface preparation while part 5 gives guidance on protective systems. Powder coating over hot dip galvanizing may be specified by EN 13438 `Paints and Varnishes Powder Organic Coatings for Galvanized or Sherardized Steel Products for Corrosion Purposes`.(plate) Painting & Powder Coating Galvanizing(steel) IntroductionPainting ObjectivesDecorative PaintingPainting For Enhanced DurabilityThe Effect of MicroclimatesPainting For Enhanced Chemical ResistanceThe painting of hot dip galvanized steel is an orthodox and well-proven practice in outdoor environments, both in Australia (AS/NZS 2312.2) and internationally (ISO 12944-5). The practice is commonly called duplex coating. However, there are examples of early failures of duplex coatings due to incorrect specifications and poor practice. The information on this website aims to avoid such failures by directing specifiers and applicators to the paint systems, surface preparation and applicatioSee more on gaa.auASTM D7396 - 14(2020) Standard Guide for Preparation of Preparing Hot Dip Galvanized Steel for Painting or Powder (steel) 1.1 This guide covers surface cleaning and various methods for treating new, continuous zinc-coated (galvanized) steel surfaces produced by either the hot-dip method or by electroplating. This guide is applicable to only surface preparation for application of liquid paint and coating products, and not for powder coating applications.(plate) Painting Galvanised Steel Painting Galvanized Steel Preparing Hot Dip Galvanized Steel for Painting or Powder (steel) Meanwhile, ASTM D7803, Practice for Preparation of Zinc (Hot-Dip Galvanized) Coated Iron and Steel Product and Hardware Surfaces for Powder Coating, has been established to detail the best practice for preparing hot-dip galvanized surfaces for powder coating.
