Start here to plan for the construction of deck or porch stairs. This article defines basic stair terms: rise, run, stringer, tread and othe rcomponents. We describe options for different types of stair supporting stringers and we give advice about choosing lumber to build deck stair stringers...
see STAIR STRINGER DEFECTS The notched stringer approach shown at left is very secure provided that the stringer depth is great enough and the cutout depth shallow enough that the remaining stringer material is strong enough to carry the weight of the stairway and its users (1-? arrow in ...
5Total rise(height from the top of your deck to the ground at the bottom end of the stringer or the total run) 6Step Run(horizontal tread depth) for each stair 7Tread type(whether you’ll use a single board or two smaller boards to create a stair tread) ...
The number of stair stringers that you need because on the dimensions of the lumber used, the width of the stair, and whether or not there can be intermediate support beneath the Stringer. Are you asking about a supporting beam below a deck?
Stairs are usually required to be at least 36 inches wide. Up to this width, you should be able to use only two stringers, while wider stairs will require an intermediary stringer. Regardless of code requirements, however, many builders always use at least three stringers for stairs between ...
Typically we use our stringer 2x lumber (before it has been cut to length) for this purpose since by definition the diagonal stringer will be longer than the horizontal stair run. This approach works to measure and design a stairway over any irregular surface. ...
What is a stair stringer? the stair stringer is the diagonal supporting structure that carries the weight of the stair assembly as well as people using the stairs. In our page top photo you can see the stair stringer that used 2x lumber. ...
If I attach the pre-made stringer from the deck to the slab, ensuring that the top of the deck to the next stair down is the same height as the rest, then the riser height from the slab to the first stair is greater than a 3/8' variation from the rest of the riser heights by ...
(4) Stairs that follow the contour of tanks or other cylindrical or spherical structures where the construction requires the inside clearance between the inside stair stringer and wall or tank side to be 8 inches or less, shall not be considered an "open side." ...
