Color-coated steel sheets-also known as profiled color-coated steel sheets-are composite materials produced by taking cold-rolled steel sheets, subjecting them to surface pretreatment, applying an organic coating, and then curing the coating through a baking process.
These sheets are primarily used in construction, including industrial plants, warehouses, and prefabricated structures. Their advantages are threefold: First, they offer excellent durability, with coatings that resist environmental erosion-such as UV radiation and acid rain-resulting in a service life of 15–20 years. Second, they are lightweight; compared to traditional concrete structures, they reduce dead weight by more than 60%, thereby lowering the load on the foundation. Third, they enhance construction efficiency; their standardized corrugated design facilitates modular installation, allowing for the completion of over 500 square meters of construction per day. Furthermore, a milky-white coating can reflect more than 80% of solar radiation, helping to reduce temperature fluctuations within the interior space.
