At Bear Hollow Supply, we carry quality cast iron legs for coffee tables, dining tables, and more. We have the largest selection of cast iron table legs available. Sizes for benches, dining tables and more. Our cast aluminum table legs are very similar to the industrial cast-iron table legs. However, aluminum keeps them lighter while keeping the rugged strength that is associated with cast-iron table legs. Want to see how we make our table legs? If so, enjoy the video below.
