This 8 foot rectangular picnic table has plastisol top and seat planks. Our plastisol picnic tables are made of a heavy duty plastic coated 3/4" expanded metal. The vandal resistant frame is made of powder-coated 4" in-ground square tubing. In-ground mounting is a permanent solution to provide a sturdy structure. Plastisol picnic tables are popular in schools and parks as they are low maintenance and vandal resistant.
