Sunset Pergola kits include virtually everything you'll need for a fully-assembled pergola. This pergola in middle of yard includes the following components (part labels are color-coded to match the image):
Sunset Pergolas are built to last a lifetime! We use thick & durable extruded vinyl that is colored throughout (not just the surface) with heavy-duty rust-free aluminum inserts that can withstand hurricane-level winds and the most extreme weather conditions. Our pergolas are manufactured right here in the USA and are backed by an unbeatable lifetime warranty.
But don't just take our word for it! We're so confident you'll be blown away by the quality of our materials that we'll happily send you a free sample (including free shipping). Each sample we send out costs us $25-30, but we're happy to eat the cost. That's how sure we are you'll choose to order a Sunset Pergola once you see the quality of our materials for yourself.

Assembling this back-yard pergola is quite easy, even for novices. What's more, you won't need any specialized tools or machinery. If you and a helper can lift up to 80 pounds and can use a drill, tape measure, level, circular saw and ladder, you're ready for a rewarding Do-It-Yourself project.
We provide the following resources to make assembly as easy as possible:
Alternatively, you can purchase the Installation Service add-on to have this free-standing pergola installed for you. The service includes anchoring the post bases to an existing concrete slab, deck or patio and anchoring the ledger plate to your home. It also includes removal & disposal of all packaging materials. See below for more info.
The CAD drawing below shows the default installation configuration for this kit for a pergola in middle of yard, which is to install the posts such that the beams and rafters extend 12 inches beyond the outside edge of the posts, creating a 12-inch overhang.
Each of the posts can, however, be installed further out (such that the post's outer edge is flush with the beams' and rafters' outer edges resulting in no overhang) OR further in (as much as 3 feet in, creating a 3-foot overhang).
See the pictures below the CAD Drawing for a side-by-side comparison of a traditional pergola with and without overhangs.
This picture shows the standard installation with posts installed 12" in from the end of the beams and rafters, creating 12" overhangs. Overhangs can be as much as 36 inches.
This picture shows an alternate installation with posts installed flush with the ends of the beams and rafters (and with flat end caps), resulting in no overhangs. Learn more here.
Shipping for this kit for a 4-post freestanding pergola is normally $999 to anywhere within mainland USA, although we sometimes run sales that discount shipping to $799, $699 or even $499. (We do not ship to Alaska, Hawaii or outside the USA at this time.)
Shipping times vary a bit based on which kit you order and where you are located. That said, we make every effort to have your kit arrive at your home within 2-3 weeks of your order date. We will stay in close contact with you to make sure you are aware of when your shipment should arrive. We will email you as soon as tracking information is available. We will also notify you via email if there are any processing or shipping delays.
IMPORTANT: Because of the size and value of the shipment, you are required to be present to receive it. You will be contacted by the freight company a few days ahead of time to schedule your delivery.
When the delivery truck arrives, you will need to unload the kit components by hand (unless you have access to a forklift). This should take no more than ~15 minutes. While a single person who can lift up to 80 pounds could unload the truck on their own, we recommend having a helper. (Please note that the delivery driver is not required to help, although they oftentimes will.)
You should verify each component against the packing list and note any missing or damaged items on your packing slip before signing. If any item is missing or damaged (which is extremely rare), please contact us and we will quickly replace it at no cost to you.
The following 1:17 video shows how easy it is to unload the truck. (Click the 'CC' icon to activate captions/subtitles.)

Installation includes complete pergola assembly and anchoring the post bases to an existing concrete slab, deck or patio (and to your home for house-attached kits). It also includes removal and disposal of all packaging materials. We will contact you to schedule installation by our third-party installation partner a couple days before your pergola is ready to ship out from our warehouse. Learn more about the optional installation service.
Many of our customers already have a local company or individual they've hired before (or are currently working with) for landscaping, patio or construction work. Such companies or individuals should have absolutely no problem installing a Sunset Pergola. Just provide them with the resources listed above.
Sunset Pergola Kits give you the unbeatable combination of...
1. High Strength - This 4-post freestanding pergola contains a rust-proof aluminum frame in all weight-bearing components (3.8mm 7-gauge in 5x5 posts / 5.7mm in 7x7 posts / 2.5mm 10-gauge in 2x8 beams & rafters). When correctly installed with optional hurricane brackets, we offer a lifetime warranty for damage caused by high winds.
2. Low Maintenance - The exterior of every piece 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. Sunset Pergolas are virtually maintenance-free and are guaranteed to never chalk, pit, discolor or become brittle.
3. Real Shade - Our pergolas are as functional as they are beautiful. As you can see in this picture, they offer serious shade and UV protection (especially if you opt for '90% shade' option, which really provides 100% shade for most of the day).
4. Lifetime Warranty - Most pergolas on the market will last 2 or 3 years... or maybe 5 years if you're really lucky. In contrast, this pergola for backyard shade is guaranteed to last a lifetime, making it more of an investment in your home's value than a one-time purchase.
We know Sunset Pergolas are far from the cheapest on the market, and we're okay with that (even proud of that). That's because Sunset Pergolas are made to last a lifetime, not to be replaced in a few short years. If you're looking for a cheap powder-coated pergola that will look nice for a couple years before it starts bowing, sagging, discoloring and falling apart, you're in the wrong place. It's very telling that over 50% of our customers are replacing an "economy/value" pergola they bought within the last couple/few years (as opposed to buying a pergola for the very first time).
Sunset Pergolas are commercial grade... luxury all the way and protected by a lifetime warranty. The entire exterior is made of USA-sourced premium extruded vinyl colored all the way through to ensure that it will never chalk, pit, chip or become brittle or discolored. And all structural, weight-bearing components (which includes all posts, beams and rafters) have a heavy-duty frame made of thick & durable American aluminum that is guaranteed to withstand heavy winds, intense heat, bitter cold and other extreme weather conditions.
If you're going to buy a pergola, don't go half-way and buy one you'll need to replace in just a few years. Spend a little more and get a Sunset Pergola that will last a lifetime and likely increase your home's value by at least as much as it costs.

See this guide about measuring your outdoor space, as well as several other factors to consider when choosing the correct width and depth dimensions.
The 4 posts (columns) included in this standalone vinyl & aluminum pergola kit are 10 feet tall, which is ideal for most customers.
If you need/want shorter posts, the posts can easily be trimmed down to a shorter height using a basic circular (or chop saw or miter saw).
If you need/want taller posts, you have a couple options:
Option #1 (preferred) - Add risers or pillars to the base so that the posts themselves are only 10’ tall. If the risers are fairly short (no more than 12” tall), a 12x12-inch square riser should be fine. But if the pillars/risers are more than 1 foot tall, we’d recommend the risers be bigger (i.e. 18x18-inch square). Here are links to a few images that illustrate how pillars & risers can be used to make the posts taller: Image 1, Image 2, Image 3, Image 4, Image 5 and Image 6.
Option #2 - For an additional $300 per 5-inch post (or $400 per 7-inch post), you can get posts up to 4 feet longer (i.e. up to a maximum of 14 feet tall). Please contact us if you're interested in this option. Please note that, because all of the third-party engineer testing and certification was done using standard 10' tall posts, we cannot warrant pergolas that have posts taller than 10' tall. This doesn't mean pergolas with taller posts aren't structurally strong. Over the years, we’ve had many customers go over 10’ tall (some as tall as 13-14 feet) without any problems whatsoever. But it’s an infrequent enough occurrence that it hasn’t made sense for us to do the official engineer testing to get them certified.
Extremely well! In fact, we are so confident this stand-alone pergola will withstand heavy winds that, when installed correctly with hurricane brackets (an optional add-on), we offer a lifetime warranty against any and all damage caused by wind.
Absolutely. This backyard pergola kit has undergone FEA testing by an independent structural engineering firm and passed with flying colors. We are so confident in the structural integrity of our system that we provide a warranty against wind damage when correctly installed using hurricane brackets. You can read more about our wind warranty here.
Very well! All weight-bearing components in this free-standing pergola kit have an internal aluminum frame to ensure your pergola won’t sag, bend, break or rust over time, even in the presence of extreme temperatures, wind, precipitation and humidity. And the premium extruded vinyl exterior is thick and durable enough that you don’t have to worry about it deforming in extreme heat or cracking/becoming brittle in the bitter cold. We guarantee it!
Sure, we encourage it! Adding a fan to keep air moving on a hot day is the perfect way to get even more enjoyment in your outside space. Lights and speakers are also a great addition. And because all of the components have an open core, it’s easy to chase wires and add boxes and switches through them.
Beam attachment brackets are not necessary, nor do they add any structural strength. They just simplify and expedite the installation step of attaching the beams to the posts (which is one of the more difficult steps in the assembly process). If you have pretty good carpentry/assembly skills, you shouldn't need beam attachment brackets. However, if you're quite inexperienced and consider yourself a novice, we'd recommend adding them to your order.
We do not offer a fully-covered system at this time. However, the 90% shade option you can select above provides 100% shade the vast majority of the day. Light only gets through when the sun is directly overhead or very close to it. In the mid-to-late afternoon and evening (which is when most people tend to use their outdoor space), the shade purlins block the sun completely and provide 100% shade. Here's a side-by-side comparison of 90% shade (on the left) and 75% shade (on the right).
Our 90% shade option is perfect because it provides complete shade for almost the entire day, but it also allows rain/snow to get through, preventing drainage issues and snow pileup.
While our website only shows 50%, 75% and 90% shade options, you can technically get ANY percentage you'd like. The higher the shade percentage, the closer the shade purlins will be to each other (i.e. for 90% shade, the purlins have 3" on-center spacing, while 75% shade has 4" on-center spacing). If you'd like a custom percentage of shade coverage (i.e. 20%, 30%, 40%, 60%, 80%, etc.), please contact us.
Hurricane brackets add structural strength and stability to prevent wind damage. Using them gives you a lifetime wind warranty. We highly recommend adding hurricane brackets (one of the optional add-ons) if you live in an area that sometimes gets winds in excess of 70-80 miles per hour.
Hurricane brackets are placed at the intersection of each beam and rafter. They are visible, but they're very discreet (matching the color of the vinyl) and look nice (see this picture).
This 18' x 20' standalone pergola has a rust-proof aluminum frame in all weight-bearing components (3.8mm 7-gauge in 5x5 posts / 5.7mm in 7x7 posts / 2.5mm 10-gauge in 2x8 beams & rafters). You simply won't find a similar-sized pergola with a thicker aluminum frame on the market.
This all-inclusive kit for a back-yard pergola offers maximum flexibility with post placement and the resulting overhangs. While the CAD drawings assume a 12-inch overhang for both beams (running the width) and rafters (running the depth), you do NOT need to install them that way. The overhang can be as little as 0 inches (i.e. no overhang at all) or as much as 36 inches, or anything in between. Here is a picture that illustrates these options.
Some customers are torn between the lower cost of a traditional kit and the more contemporary look (but 20-40% higher cost) of a modern kit. If you're in this camp, you may want to consider what we call our "hybrid" design. You actually just purchase a traditional kit (so you get the lower price), but you customize it and install it in a way that gives it a more contemporary look (i.e. no overhangs, and clean squared-off corners). Here's what a "hybrid" pergola looks like from underneath and from the outside.
We have multiple sales throughout the year associated with various holidays, seasons and events. The deepest discount we offer in ANY sale event is $1,000 off + half-off shipping ($499 instead of the regular $999).
If it's during business hours (Mon-Fri 8am-5pm MT), the best ways to get help are to call us (877-760-6992) or start a live chat. If it's outside of business hours, you can call and leave a message or submit a help ticket here.
