All metal components of the 22123 picnic table are powder coated to help the metal resist rusting. The table top and benches are both made with UV-resistant HDPE plastic. Both of these features help the table hold up well in just about any weather. That said, eventually, all parts of this picnic table will breakdown. If there is a particular season where you know that the table will not be used, or will be used infrequently, the life of the table will be lengthened if you take down and store the table in a dry spot.
