The supporting structure of Paladin growboxes is a reinforced full metal frame, which ensures adequate stiffness and load capacity. Elements of the frame are made of powder coated galvanized steel pipes with a diameter of 16-22mm and wall thickness of 0,8-1mm, which guarantees durability and low weight. We chose to use steel corner connectors equipped with plastic covers and metal snaps in order to make the whole framework extremely durable and easy to put together.
