PVC Pergola

Does anyone have experience building a pergola out of Azek, Trex or some other man made material? I built a beautiful pergola about 9 years ago out of pressure treated material and despite routine staining, is showing signs of serious rot. I want something maintenance free that will last in a shore environment. Are there structural components available for the rafters and beams?

Composite or plastic is only for finish, not structural so your limited to PT or cedar!

Trex and a few other manufacturers are now making structural components with aluminum substructure. I was referring to this new material.

There are pergolas made of PVC, but synthetic deck boards are not PVC. Working with PVC is quite different than wood and most home centers don't stock much in PVC so you would be best looking for a kit. A kit will probably have the pieces cut to length and more importantly the difficult rectangular holes will already be cut and it will have the special brackets needed to hold it all together.

I just cruised the Trex site and didn't find anything, there are some commercial references but Id venture the cost is prohibitive for residential use.

If you have some links, please share!

Yes, a kit like the one you linked would be a good way to go. I would NOT attempt using standard synthetic decking materials but something designed for the task should work great. I have some poly outdoor furniture (similar material to Trex) that has held up very well.

Oh agreed, regarding standard Azek or Trex planking. I will investigate these new (at least to me) engineered structural components.
