The main difference between teak outdoor tables and aluminum outdoor tables is the weight. Teak tables are typically much heavier than aluminum tables, so, if you like to rearrange your patio layout every few days or weeks, aluminum may be the better option. Here’s a bit more information on the differences between teak and aluminum outdoor tables. Teak is a high-quality, naturally water-resistant hardwood known for its rich appearance, heavy feel, and ability to stand up to the weather. It’s extremely durable and can last for decades with the proper care. If left untreated, teak tables can develop a silvery patina that many people are a fan of, but if you’d rather keep the original golden-brown look of natural teak, you can oil your teak furniture each season. Aluminum is a lightweight, rust-resistant metal that comes in a variety of styles and finishes. It’s highly durable and typically only requires occasional cleaning with soap and water. Depending on the quality of the metal, it may be more vulnerable to dents and scratches than teak wood.
