This research used research and development method with stages of analysis, design and development to produce props of metal coating plates oriented chemical representation. This research is driven by the importance of a chemical learning medium that can present macroscopic, submicroscopic and symbolic representations on metallic coating materials so that material can be delivered well to students. Based on the results of the research, the product is obtained in the form of metal coating props with the characteristics of combining macroscopic, submicroscopic and symbolic representations with guidebooks and worksheets. Validation results indicate that the product is valid with the acquisition of the value of r-count on props of 0.92.
