Precoated steel sheets are widely used as construction materials, such as roofing and sidings. In this report, organic coatings on Zn and Zn-Al alloy plated steel sheets are mainly described as precoated steel sheets. Trends, material profiles, properties (weather resistance, corrosion resistance), and evaluation methods for the precoated steel sheets are reviewed. In addition, thin organic coatings on Zn-Al alloy plated steel sheets also are described.
