Visual Guide to Powder Coating on Galvanised Steel
Powder coating over galvanised steel involves applying a dry powder to the metal surface that has been previously treated with a layer of zinc. This combination offers enhanced corrosion resistance and an attractive finish, ideal for exterior applications. The powder adheres electrostatically and is cured under heat to form a durable, protective layer.
The process starts with thorough surface preparation, often involving degreasing and light abrasive blasting to improve powder adhesion. This step is crucial as it removes contaminants and provides a roughened surface profile, ensuring optimal coating performance and longevity. Follow up with appropriate pre-treatment tailored to galvanized surfaces to prevent common issues such as outgassing.
After preparation, the chosen powder is applied evenly, maintaining the correct thickness to avoid defects. The coated steel is then cured in a special oven, solidifying the finish. For best results, professional handling and precise control over application parameters are recommended, leading to a high-quality finish that stands the test of time.
