Our standard vinyl gazebos are made of pressure-treated southern yellow pine covered with vinyl. Our heavy-duty floor consists of double 2×6 joists and 1″ thick maintenance-free composite decking boards. The posts are constructed of a white vinyl 4×4 sleeve with a solid wood core, they support 36″ high rails as standard. They come with arched corner braces and 6″ top spindles. The roof is built with double 2×4 rafters and sheeted with beautiful 1×6 tongue & groove boards covered with roofing paper and architectural asphalt shingles. The underside of the roof is coated with a rich mahogany stain for a beautiful hardwood appearance.
