Waterproof & Anti-fade Seaside Wall Panels

A: Yes, our wall panels are specifically designed for the high humidity and rainy environment of the seaside. First, the material itself has an extremely low water absorption rate (usually ≤0.5%), far lower than ordinary wood or cement board, making it difficult for water molecules to penetrate. Second, the installation system has a specialized waterproof structure: the panels use tongue-and-groove joints or concealed fasteners, with pre-installed drainage channels and expansion joints; at window edges, corners, and other joints, special waterproof strips or sealant are used to create a "rain curtain" drainage path, rather than relying solely on adhesive to block water. As long as the installation is carried out according to the construction specifications, it can ensure no leakage even during heavy rain.

A: Our products primarily rely on UV stabilizers and highly weather-resistant surface materials (such as ASA or fluorocarbon coatings) for fade resistance. In accelerated aging tests (such as QUV 2000 hours or more), the color difference value ΔE can be controlled to ≤3, which corresponds to virtually no visible fading within 10-15 years of actual use.
At the same time, anti-aging additives are added to the material, preventing brittleness and powdering. For extremely harsh environments (such as equatorial regions), we can also provide higher-grade surface coatings, extending the color retention period to up to 20 years. Of course, any material will experience slight color changes under long-term direct sunlight, but our products control these changes within the highest industry standards.

A: This is precisely the core advantage of our products. The wall panels themselves have extremely strong resistance to salt spray corrosion: for example, the plastic matrix of WPC material (HDPE or PVC) is resistant to acids, alkalis, and salts, while the fiber cement board isolates salt through a dense formula and weather-resistant coating. We have conducted neutral salt spray tests (≥1000 hours), and the surface showed no blistering or peeling.
For fasteners, we uniformly use stainless steel 304 or 316 grade screws, and we add nylon washers or apply anti-rust paste during installation to prevent electrochemical corrosion. In addition, we also apply anti-corrosion treatment at the connection between the keel and the wall to ensure the long-term stability of the entire system in the coastal environment.
