Triple Bench Chairs are made of sturdy ribbed steel and have a heavy oven cured plastisol coating to give them a smooth shiny finish. The frames are constructed from 2 7/8"galvanized tubing. Each chair is angled at 15 degrees. They come in sections of 3 chairs either with backs or flat. They are attached to a support bar which can be in-ground or surface mount. These make execellent seats surrounding public gardens and circular fountains or place around trees in the shade!
