Stone-coated metal roofs combine the texture of natural or artificial stone with the advantages of metal substrates, and have significant aesthetics. They can simulate natural textures and customize designs through surface treatment technologies such as imitation stone. They have excellent durability, strong weather and aging resistance, a service life of more than 30 years and low maintenance costs. They meet green standards, are environmentally friendly and recyclable during the production and use stages, and the heat-insulating reflective coating of some products can reduce energy consumption. They have outstanding fire resistance, and both metal and coating are non-flammable. Although the initial investment is relatively high in terms of economy, the long life and energy saving can save long-term costs. At the same time, they are easy to install, and metal tiles are light in weight and can be directly covered on existing roofs, reducing construction burden and waste.
