If you need an 11-step stair stringer, verify the number of risers and the finished floor-to-floor height before buying: the products listed here include one adjustable 10- or 11-step kit, one 10-step steel option, and three shorter alternatives. The Hunt Supply kit is the closest match for an 11-step staircase; the DIYHD stringers suit an 81-inch deck height with 10 steps. The remaining products are not 11-step stringers and are included only for buyers comparing shorter stair runs.

The Hunt Supply 10–11-Step Steel Stringer Kit
Best for: Buyers who need a 10- or 11-riser staircase for a raised hunting blind or tower. This is the only listed option that explicitly accommodates 11 risers, making it the closest match to the keyword.
The modular steel stringers adjust for a floor-to-floor rise of 72 to 84 inches, with a listed 107-inch run. The stated riser height is 7 7/16 inches. Connectors and top hook straps are described as allowing adjustment within the height range without cutting steel.
Limitation: Treads and rails are not included. Confirm the actual rise, run, and intended installation before choosing it; its listed 107-inch run requires more horizontal space than a compact stairway.
DIYHD 10-Step Outdoor Steel Stringers
Best for: Deck, porch, or patio projects with an 81-inch deck height that call for 10 steps rather than 11. The product is a two-pack of one-piece steel stringers with a powder-coated black finish. Its description states that the stringers support up to 500 pounds.
This option is a better fit when the specified 10-step configuration matches the project’s measured height. Its outdoor stair applications and coated steel construction make it relevant to buyers comparing deck stringers.
Limitation: It is listed as a 10-step product, not an 11-step stringer. Do not assume it will fit a different rise or step count; check the product dimensions and project layout first.
Toriexon 6-Step Steel Stair Riser
Best for: Buyers building a shorter outdoor stairway for a deck, porch, courtyard, doorway, or hot tub. The listed configuration is a two-pack of six-step steel risers with reinforcing support legs.
The product description specifies a powder-coated finish intended to resist outdoor weather exposure and pre-drilled holes for installation. It may be worth comparing with other short-run options when a six-step layout suits the measured height.
Limitation: This is not an 11-step product. The description refers to a 50-inch deck height, so confirm that its dimensions match the planned stair rise and attachment points.
UFP 279712 3-Step Stair Stringer
Best for: Buyers comparing a basic, short stair run. The product name identifies a three-step stringer sized for 2-by-12 material, supplied in a quantity of six.
That quantity may be useful for projects requiring multiple stringers, but the listing information provided here does not specify the complete layout, rise, or installation details. Compare those measurements with the project before purchasing.
Limitation: Three steps are substantially fewer than 11, so this is not a substitute for a tall stair stringer. Product details available here are limited.
5-Step Stringer With Reinforcing Support Legs
Best for: Outdoor deck projects that need a five-step metal stringer for a listed 42.5-inch deck height. The product name describes a two-piece set with reinforcing support legs and a black finish.
Choose this option only if a five-step configuration fits the measured stair rise. Its stated step count makes it more relevant to short access stairs than to an 11-step installation.
Limitation: The product details supplied do not state additional dimensions or installation features. Confirm the rise and attachment requirements before selecting it.
Buying Guide: How to Choose an 11-Step Stair Stringer
Does the stringer need exactly 11 steps?
Check whether the listing specifies 11 risers, 11 treads, or another way of counting steps. These terms can be used differently in product listings and project plans. Of the options here, The Hunt Supply kit explicitly lists 10 or 11 risers; the DIYHD option is listed for 10 steps. The other three are shorter products.
How do you match the stair rise and run?
Measure vertically from the lower landing to the finished upper floor or deck surface. Compare that floor-to-floor rise with the stringer’s stated range. Then check the horizontal run to make sure the stairs fit the available space. The Hunt Supply kit lists a 72-to-84-inch rise and a 107-inch run; the DIYHD product is associated with an 81-inch deck height.
What should you compare besides step count?
- Material and finish: The listed options include steel products, and some descriptions specify a powder-coated finish. Check the product details for the intended exposure and maintenance needs.
- Included components: Confirm whether the package includes one or more stringers, connectors, treads, rails, or support legs. The Hunt Supply kit states that treads and rails are not included.
- Installation details: Review attachment points and project requirements. Toriexon’s description mentions pre-drilled holes, but details vary between listings.
- Space and layout: Compare stair width and run with the installation area, and verify measurements before ordering.
For an 11-riser project, start with the adjustable 10–11-step kit, then confirm its rise and run against the site measurements. If those dimensions do not match, do not assume a 10-step or shorter stringer can be adapted without checking the manufacturer’s specifications.
Frequently Asked Questions
Which listed product is made for 11 steps?
The Hunt Supply kit is listed for 10 or 11 risers. It is the only product in this selection that explicitly includes an 11-riser configuration.
Is a 10-step stringer interchangeable with an 11-step stringer?
Not automatically. Step count, total rise, and stair run affect fit. Match the product specifications to the measured project dimensions.
How much vertical rise does the 10–11-step kit cover?
The Hunt Supply product description lists a floor-to-floor rise range of 72 to 84 inches and a 107-inch run.
Are treads included with the Hunt Supply kit?
No. Its supplied product information states that treads and rails are not included.
Can the five- or six-step options replace an 11-step stringer?
No. They are listed as shorter stair products. Consider them only when the project’s required step count and rise match their specifications.
