This 48" square single post wooden picnic table is excellent for your park. The heavy-duty, vandal-resistant design has a center post made of 6" square tube. Surface mounting is a great solution where vandalism is a concern. The frame is hot-dip galvanized or powder coated steel and the seat support is a 3 1/2" O.D. pipe. This table is perfect for an HOA or apartment community. The wood is treated with MCA, a copper-based clean, odorless, non-staining, and non-irritating pressure treatment that is safe for the environment and protects against termites and decay.
