What are the best ways to prevent warping in stone outdoor oval tables with mixed materials?

Warping in stone outdoor oval tables with mixed materials can be a common issue due to exposure to varying weather conditions. To prevent this, start by choosing high-quality, weather-resistant materials such as treated stone and durable metals or composites. Ensure proper sealing of the stone surface to protect it from moisture absorption, which can lead to warping over time. Additionally, use a stable base or frame made from materials like stainless steel or aluminum to provide structural support and reduce stress on the stone. Regular maintenance, including cleaning and resealing, is crucial to prolong the table's lifespan. Lastly, consider placing the table in a shaded area or using a protective cover during extreme weather to minimize exposure to direct sunlight and rain. By following these steps, you can maintain the beauty and functionality of your outdoor oval table for years to come.
