The application of coated steel in architectural decoration has multiple advantages. First, its weather resistance and corrosion resistance enable it to maintain long-term beauty and stability in various climate conditions. Secondly, the surface coating of coated steel is rich and diverse, and can provide a variety of colors and textures to meet the needs of different architectural styles. In addition, it is easy to clean and has strong anti-fouling ability, and the maintenance cost is low. Coated steel also has good processing performance and can be easily cut, bent and formed, which is suitable for complex design requirements. At the same time, its strength and lightweight characteristics also help to reduce the load on the building structure.
