The sealing performance of a corten steel wall art cladding panels would depend on several factors such as the design of the wall, the quality of the installation, and the type of sealing materials used.Corten steel, also known as weathering steel, forms a protective layer of rust on its surface when exposed to the elements. This layer acts as a barrier to further corrosion and can provide a unique aesthetic appeal. However, it is important to note that corten steel is not inherently waterproof and may require additional sealing measures to prevent water infiltration.The sealing performance of a corten steel curtain wall can be improved by using appropriate sealing materials such as sealants, gaskets, and weatherstripping. These materials can be applied at the joints between the wall panels, windows, and doors to prevent water from entering the building envelope. Proper installation is also critical to ensure that the sealing materials are applied correctly and the joints are properly aligned and sealed.It is recommended to consult with a qualified engineer or architect to ensure that the corten steel curtain wall meets the required performance standards and is properly designed, installed, and sealed to provide the desired level of performance.
