How do rattan outdoor chairs handle heavy rainfall without warping?

Rattan outdoor chairs are designed to endure heavy rainfall without warping due to their weather-resistant properties. Modern synthetic rattan, commonly used in outdoor furniture, is crafted from high-density polyethylene (HDPE) or other durable plastics, which repel water and resist moisture absorption. Unlike natural rattan, these materials do not swell or warp when exposed to rain. Additionally, the woven design allows water to drain quickly, preventing pooling and prolonged exposure. To further enhance durability, many rattan chairs feature powder-coated aluminum frames that resist rust and corrosion. Regular maintenance, such as covering or storing chairs during extreme weather, can also prolong their lifespan. With these features, rattan outdoor chairs remain sturdy and attractive even after frequent rain exposure.
