This table is fabricated with a newer "engineered" hardwood. Thermally Treated Ash. This material has superior rot and pest resistance due to the heat treatment which basically renders the wood "unattractive" to wood boring pests. No harsh pesticides or herbicides used at all. One of it's primary uses is exterior siding, however it is also well suited for outdoor furnishings and is available in industry standard dimensions.
The size of this table is 120" x 48" x 30". The thickness of the tabletop is 1.75". Very stout and durable as an outdoor table should be.
