What are the best ways to prevent warping in metal outdoor rectangular tables with glass tops?

Warping in metal outdoor rectangular tables with glass tops can be a common issue due to exposure to varying weather conditions. To prevent this, start by choosing high-quality, weather-resistant materials for both the metal frame and glass top. Ensure the table is placed on a level surface to avoid uneven stress on the frame. Regularly clean and inspect the table for any signs of rust or damage, as these can weaken the structure over time. Applying a protective coating to the metal frame can also help shield it from moisture and temperature changes. Additionally, consider using a cover when the table is not in use to protect it from extreme weather conditions. By following these steps, you can maintain the integrity and appearance of your outdoor table for years to come.
