When choosing outdoor furniture for urban spaces—such as balconies, rooftops, or patios—weather resistance is a critical factor. Two popular materials are rattan (often synthetic rattan, or resin wicker) and aluminum. This article compares their weather resistance to help you make an informed decision.
First, consider synthetic rattan. Modern synthetic rattan is woven from resin or polyethylene fibers, designed specifically to withstand outdoor conditions. It is highly resistant to UV rays, meaning it will not fade or become brittle after prolonged sun exposure. It also resists moisture, rain, and humidity without rotting, warping, or cracking—unlike natural rattan. Most synthetic rattan furniture is waterproof and can handle light rain, but standing water or heavy prolonged downpours may cause water to seep into the frames or cushions if not properly sealed. Additionally, synthetic rattan performs well in moderate temperature fluctuations but can become slightly brittle in extreme cold (below freezing) if the quality is low.
Now compare aluminum. Aluminum is naturally corrosion-resistant, especially when powder-coated or anodized, making it ideal for rain, snow, and coastal environments with salty air. It does not rust, warp, or rot. Aluminum handles heat well—it won’t deform under high temperatures—and it does not crack in freezing temperatures. However, aluminum can become very hot to the touch in direct sunlight, and its surface can be prone to scratches or dents if the coating is thin. Also, aluminum is lighter than rattan, which can be an advantage for moving but a disadvantage in windy urban conditions (it may tip over).
In terms of maintenance, synthetic rattan requires occasional cleaning with mild soap and water to remove dirt and pollen, and you should store cushions indoors. Aluminum needs minimal maintenance—just wiping off dirt and checking for scratches to avoid rust on exposed metal.
Overall, for weather resistance in urban environments, aluminum has a slight edge in long-term durability and moisture protection, especially in very humid, rainy, or coastal areas. Synthetic rattan offers excellent UV resistance and a more natural look, but it may degrade faster if exposed to persistent standing water or extreme cold. For most urban settings with moderate climates, both materials perform well, but aluminum is more forgiving in harsh conditions. If you prefer the aesthetic of woven textures, choose high-quality synthetic rattan with a robust frame (e.g., aluminum or steel) and always use furniture covers during severe weather.
