This heavy-duty round picnic table is perfect for any commercial or heavy usage setting. It is a sturdy and significant piece of garden furniture. The wood is pressure treated with Tanalith E to help prevent rotting and decay. Pressure-treating forces the treatment deeper into the wood so the timbers have a much longer lifespan than ordinary treatments. The timbers are also patterned with anti-warp grooves so there will be no buckling or warping due to temperature changes. Natural splitting and cracking may occur but will not affect the lifetime or structure of the product.
