This popular square table has a 1-5/8" all-welded walk-through frame. The table also has a perforated rolled-style design and a surface mount, which is a large 4-hole plate that is welded to the center post. The powder-coated frame is available in a variety of colors, as is the thermoplastic table and seats. The thermoplastic coating provides ultra violet protection, impact resistance, superior ultra-high adhesion and excellent mechanical performance.
