5-Step Ground Contact Pressure Treated Pine Stair Stringer

Hi Cletus831, Based on the 42-inch height, you would need a 6-step stringer with a riser height of 7 in. Unfortunately, the treated stringers that we have are set-up for a 6.75 in. step height. This is not going to work in your situation. Please ask a Pro Associate at Home Depot about a special order or considering building it yourself/hiring a handyman/carpenter or someone who is familiar with the building code in your area.

Hello Alex, We looked at the height of your wall, and it is about 1/8th of an inch. off to work with our 7-step stringer. We can suggest that you see if the manufacturer can build you a custom stringer, or that you build one yourself.

AA, We want to make sure that we understand your question. Do you mean stair riser height , stair tread depth (what your foot stands on), or the spacing of the stringer? We calculated the step height for both 16 in. and 18 in. The 16 in. height would give you a step riser height of 5.33 in.; this is a bit shallow, in our opinion, and it could be a trip hazard. The 18 in. height, though, would give you a 6 in. height step, this seems more reasonable and less of a hazard to us. The 3-step stringer is what you would need for the stringer with either of the two scenarios. If we are incorrect in replying to your question, please write to us again and we'll do our best to address your request.

Hello Cody, Here is the math that we suggest: Take the total height that you intend to span - 25 in., and divide that number by 7.75 in. That gives us 3.22. Round up to the next full number, and you get 4. You need a 4-step stringer. For the step height, divide your original number - 25 by 4 (the number of steps that your stringer is built to accommodate). That is 6.25. Your riser height would be 6.25, and that is not going to work with the 4-step stringer because our stringer is an inch too tall. You will need make a special stringer or inquire with a PRO associate about ordering one from the manufacturer.

Hello Question, Unfortunately, it looks like you need a 7-step stringer, and Home Depot does not have that in pressure-treated wood. The good news, however, is that you can contact a PRO associate about making a special order request from the manufacturer. If you'd prefer not to go this route, though, we suggest hiring a carpenter who is familiar with the building code in your area or building your own stringer from a 2 x 12 pressure-treated board.

Hello Rey, It seems that you will need a 12-step. This would be a custom order or one that you/a carpenter would have to construct from a 2 x 12.

Hi JaredV, We do not believe that would be a good plan and would not encourage you to do it. This would be a huge trip hazard.

Hi Larry, This is a single stringer.

Hello 1T, We attempted to figure discern what width of the depth of the stair related to, but weren't sure if you were referring to how wide the staircase could be with a pair of stringers, or if there was a typo and you meant width and depth of the stringer. Actual dimensions for the stringer are 1.5 in. x 11.25 in. x 35.64 in., and the riser height is 6-3/4 in.,with run height being 10 in. Also, all of our stringers are cut from 2 x 12s. If this is not the information which you were looking for, though, we suggest that you go to the boxed-off Info & Guides section of the product page and click on FAQ; this link has all the drawings and dimensions for 3-step up to a 6-step stringer. We hope that this will help.
