For an outdoor table, it's recommended to use materials that are durable and weather-resistant. A popular choice is teak wood, known for its natural oils that protect it against moisture, insects, and decay. Teak is also highly durable and requires minimal maintenance. Another option is aluminum, which is lightweight, corrosion-resistant, and easy to clean. Wrought iron is a sturdy and long-lasting choice, but it may require occasional repainting to protect against rust. For a more modern look, synthetic materials like resin or Polywood are popular choices as they are water-resistant, UV-resistant, and require minimal upkeep. Ultimately, the choice of material depends on personal preference, style, and budget.
