Why a Sunset Pergola?
Sunset Pergolas offer the perfect combination of quality, beauty and affordability. The all-vinyl exterior is elegant and virtually maintenance-free, and the aluminum frame is both structurally strong and rust-proof.
Heavy-Duty Aluminum Frame
Sunset Pergolas are built to last - and to stay beautiful - for decades. The sturdy aluminum frame ensures that your pergola will not sag, bow, bend, break or rust over time.
The half-inch thick welded post base and stainless steel fasteners will hold your pergola securely in place, even in extreme weather conditions. The posts (columns) can easily be trimmed to your preferred height and attached to virtually any surface (deck, concrete slab, pillar or footing).
Premium Vinyl Exterior
With such quality on the inside, do you think we would skimp on the outside? Absolutely not! The exterior of every piece (the posts, beams, rafters and shade purlins… everything!) is made of premium extruded vinyl that is as beautiful as it is durable. Anyone who has ever had both a vinyl fence and a wooden fence knows how much easier it is to clean and maintain vinyl. Our pergolas are virtually maintenance-free and are guaranteed to never chalk, pit, discolor or become brittle.
Sunset Pergolas are manufactured right here in the USA and are protected by a lifetime warranty. Order a free sample or read more about our high-quality materials.

Easy Assembly: DIY or Installed For You
Assembling a Sunset Pergola is quite simple and straightforward. Even novices with little to no construction experience can bang it out in a day or two. You don’t need any specialized tools, either. We provide fully-illustrated installation instructions (see these simplified instructions), several demo videos (for the more complicated steps) and will even provide live help via FaceTime or Skype for free (if needed).
Or you can hire an installer near you to assemble and install your pergola for you. Check out this list of installers throughout the country who have 1) completed our installation training course, 2) passed a test we administer, and 3) already installed our pergolas multiple times (in most cases).
