Outdoor and semi-outdoor glass projects set higher standards for hardware weather resistance. Manufacturers upgrade surface treatment technologies to improve anti-corrosion and anti-fading performance of glass clamps, hinges and handles. Beyond traditional polishing, electrostatic spraying and PVD coating are widely used to form protective layers against rain and UV rays. Different processes suit varied scenarios: PVD coated products fit humid coastal areas, while spraying supports rich color choices. Pre-treatment procedures remove surface impurities to improve coating adhesion. Long-term aging tests track appearance changes under different environments, helping adjust technical parameters and supply hardware for coastal buildings and outdoor glass partitions.
