Our Heavy-Duty Picnic Table Frame Kits are constructed with commercial-grade steel that utilizes 1-5/8" tubular metal for the frame construction. This item is available in two different weather-resistance options: hot-dipped galvanized (silver) and powder-coated (black). Use your choice of material and color combinations for the table planks in order to create your version of the ideal picnic table. This frame is intended to be coupled with 12' table planks. This product has been designed with a wide base to prevent tipping over and welded for increased rigidity.
