UV-proof coatings play a key role in improving the durability of invisible grill material. These coatings protect the stainless-steel cables and nylon layers from sun damage, discoloration, and weakening over time. By blocking harmful UV rays, the coating ensures the material maintains its strength, flexibility, and appearance for years. This is particularly important in open balconies exposed to direct sunlight. UV-proof invisible grill material guarantees long-lasting safety while keeping the grill clear and visually unobtrusive.
