Each brand's own figure for the model named, read October 16, 2026. Hurricane categories from the National Hurricane Center. * Rival claim. Pergolux and StruXure print no figure for the model: see receipts 1 and 4.
Open five pergola pages and you'll find five wind ratings between 70 and 170 mph. Read the same brand's spec sheet, store listing and FAQ, and the figure can change three times. That's not always a trick. Sometimes it's a range rating standing in for a model rating. Sometimes it's the louvers-open figure, which is always higher. Sometimes it's a number tied to a foundation almost nobody pours.
This chapter shows you how to tell which is which, with the pages themselves as the receipts.
The seven specs that matter
Ignore the colors and the lighting. Seven lines on the spec sheet decide whether the roof is still standing in 2036.
1. Aluminum grade: T5 or T6. Almost every louvered pergola is 6063 aluminum. What varies is the temper. T6 gets a controlled heat treatment and is the stronger of the two; T5 is the cheaper, more common one. Hansø prints 6063-T6 for the Horizon and the Apex and 6063-T5 for the Kit; Pergolux prints 6063-T5 for the Skydance S3; StruXure prints "powder-coated aluminum" and no temper.1,2,9,3Look for: the temper named for the load-bearing members. A brand that prints "6063 extruded aluminum" and stops there is hoping you won't ask.
2. The wind rating, and whether it's for your model. Chapter 3 below. The short rule: a wind figure means something when it's printed for the model, with the louvers closed, and the brand can hand you the engineering behind it.
3. Snow load, and the size asterisk. Snow is published in pounds per square foot. Hansø prints 60 PSF for the Horizon and 65 for the Apex; BonPergola prints a range per model, 20 to 35 PSF for the Villa and 30 to 52 for the Villa 2.0; Pergolux prints a site-wide "75 psf" and no figure for the Skydance S3.1,2,5,6,3Look for: a figure for your size. "Up to" is the best size in the range, not yours.
4. Deflection. How far a beam bends under load before it counts as inadequate, written as L/60, L/120, L/180. The stricter the ratio, the stiffer the roof. Almost nobody prints it. The Luxury Pergola publishes a deflection standard on its own pages.4Look for: any brand that prints one at all.
5. Louver construction: single wall or double. A single-wall louver is one sheet of extruded aluminum. A double-wall louver is two layers with an air gap, heavier, quieter in wind and rain, and cooler underneath. Hansø builds the Horizon's louvers double and dampened, and rates the shade "up to 15°F cooler underneath on the hottest days," its own figure.1Look for: double wall if you'll use the roof in summer.
6. Coating. The powder coat is what stands between the aluminum and the sun, the salt and the pool water, and it's the cheapest part to skimp on. Hansø names its supplier on the Horizon page: AkzoNobel. The Kit carries a three-layer coat.1,2Look for: a named supplier, or at least a named number of layers.
7. Motor and controls. A crank, a motor with a remote, or a motor that answers to your phone. The Horizon works with the Hansø app, Alexa, Google Home and Apple HomeKit, with a rain sensor that closes the roof at the first drop. The Pergolux Skydance S3 runs on the Matter standard with Alexa and Google Home. StruXure's controls come with the dealer install.1,3,9Look for: the one you'll use every evening, which is the phone.
The wind rating, with receipts
Four receipts, each a page we read on October 16, 2026.
Receipt 1: a range rating standing in for a model rating
Pergolux prints "up to 165 mph winds, 75 psf. snow loads" in the footer of its product pages. Open the Skydance S3 page and there's no wind or snow figure for the Skydance S3 itself.3 "Up to" is the best case across the catalog. It tells you nothing about the size you're buying. The S3's frame is 6063-T5, the softer temper.3
Receipt 2: the figure with a foundation attached
Mirador prints 90.2 mph and 20.8 PSF for the 111S "with professional anchoring." Its FAQ prints 73 to 82 mph and 13.8 to 17.7 PSF.7 Both are Mirador's own figures. The gap between them is the foundation. If your install is a 4-inch patio slab and expansion bolts, the FAQ figure is closer to yours.
Receipt 3: the same roof, three figures
The Luxury Pergola prints 170 mph in its spec table, "180 to 200 mph" in its store listing and "up to 200+ mph" on its product page.4 It also prints its deflection standard, which most brands don't. Ask which figure applies to your size, in writing.
Receipt 4: what paper looks like
StruXure prints no wind figure at all. It prints something rarer: its blog links ICC-ES report ESR-5321P, and it calls itself "the only louvered pergola manufacturer with ICC certification."9,10 That's a third party with a name. Hansø prints its figures per model: 165 mph and 60 PSF for the Horizon, 167 and 65 for the Apex, 120 and 25 for the Kit, each with the louvers closed.1,2,11
A real engineering report names the building code it was run against, the wind and snow standard, the software, the load for each size, and the licensed engineer who signed it. Ask every brand for one. The ones that have it send it.
The decoder
Her rule still holds: print this, bring it shopping. A roof should sit in the first column on every row. Two rows in the last column is a pass.

The 7-spec decoder. "Insist" is what the best pages print today; "walk away" is what the thinnest pages print.
Choose by climate, not by marketing
Coastal, within five miles of salt water. The enemy is corrosion where aluminum meets steel. Look for stainless plates and fasteners and a named coating. Hansø prints 304 stainless steel plates under the Horizon's posts and an AkzoNobel coat.1 Mirador's 111S pairs steel louvers with an aluminum frame, which is the pairing you watch at the coast.7
Snow belt, more than 36 inches a year. Look for 50 PSF or more printed for your size. A 10x13 roof under 60 PSF carries 7,800 pounds. The Horizon prints 60, the Apex 65.1,2 A 25 PSF roof is a mild-climate roof.
Hot sun belt. Look for double-wall louvers. The difference under them is the difference between a tin roof and a porch. Hansø's own figure for the Horizon is "up to 15°F cooler underneath."1

Hansø's own published figures. Checked Oct 19, 2026
The Horizon is the one on this page that prints its figures for its own model and names the parts behind them: 165 mph with the louvers closed, 60 PSF of snow, 6063-T6 posts, beams and blades, an AkzoNobel coat, 304 stainless plates under the posts.1 The National Hurricane Center starts Category 5 at 157 mph.8
The roof opens, closes and tilts from the app, Alexa, Google Home or Apple HomeKit. A rain sensor ($276) shuts it at the first drop.1,11
What we like
165 mph and 60 PSF, printed for this model, louvers closed1
Delivery takes weeks, not days. Hansø says its delivery times are approximate12
Fixed sizes only; no custom spans
The 10-year frame warranty goes to the first owner and needs registering within 30 days13
After about a year of research and conversations, we finally pulled the trigger on a Hansø Horizon Smart Pergola
Buy it if you want the strongest printed numbers under $10,000 and a roof you talk to. If you live where roofs carry more snow, the Apex prints 65 PSF.2
Coverage and partner features

Every wind figure assumes a foundation. Mirador prints two figures for the same roof, one with professional anchoring and one without.7 Ask the brand what it assumed. A 4-inch concrete slab works for most kits; a gravel patio needs concrete point footings at each post; grass doesn't work. Budget $400 to $1,500 for new footings on a 10x13 roof, which no direct-to-consumer price includes.
What does a louvers-open rating mean?
Open louvers let the wind through, so the open figure is always higher. The number that protects the roof in a storm is the closed one. If a page prints only the open figure, ask for the closed one.
Do I need a permit?
A detached roof under 200 square feet usually doesn't need one; an attached roof usually does, and electrical work needs its own. HOAs set their own rules. Hansø lets you cancel free of charge within seven days of purchase; after that a restocking fee applies.14
Can I get the engineering report?
Ask. Hansø's phone line is +1 760-280-6099. StruXure's paper is public: ICC-ES ESR-5321P.10 If a brand won't send anything, you have your answer.
