When selecting urban outdoor leisure chairs, UV resistance and color stability are critical factors for long-term durability and aesthetic appeal. Among common materials, aluminum stands out for its exceptional UV resistance and inherent color stability through anodization or powder coating processes. Synthetic resin, particularly high-density polyethylene (HDPE), demonstrates remarkable color retention through integrated UV inhibitors that prevent molecular breakdown. Wood plastic composite (WPC) offers moderate performance with color consistency depending on the quality of synthetic pigments and protective coatings. Powder-coated steel provides excellent protection when treated with specialized UV-resistant coatings, though may require maintenance over time. Traditional materials like natural wood show poor UV resistance without frequent sealing treatments. For optimal performance in sunny urban environments, anodized aluminum and HDPE synthetic resin emerge as superior choices, maintaining color integrity and structural stability through prolonged UV exposure while requiring minimal maintenance.
