What are the best ways to prevent warping in wood outdoor rectangular tables with mixed materials?

Warping is a common issue for wood outdoor rectangular tables, especially when mixed materials are involved. To prevent warping, start by selecting high-quality, weather-resistant wood such as teak or cedar. Ensure proper sealing and finishing with waterproof coatings to protect against moisture. Use mixed materials like metal or composite for structural support, as they are less prone to warping. Regularly clean and maintain the table, avoiding prolonged exposure to direct sunlight or rain. Finally, store the table indoors during harsh weather conditions to extend its lifespan and keep it warp-free.
