physical - Why do stairs have overhangs? - User Experience Stack Many construction codes in fact require nosing overhangs of 1/2 inch or more, particularly if the going is less than 10 inches. Clearly there is a convincing view that nosings are a necessary safety device, a view supported by a study for the National Bureau of Standards (Templer et al. 1978). for the stairs that were observed and analyzed, it was found that the high-risk stairs (compared to a group of low-risk stairs) had no nosing projections. He goes on in the book to explain that (based

You don''t even need to cut stair stringers. decks and transitions between levels of tiered decks. Many deck builders use this technique to build a wide set of stairs across the front or side of deck. Box stairs do not Most deck builders use 2x6 material to frame the stair boxes and use (2) 5/4x6 deck boards for each tread with a 1/2" overhang over the riser board. Cut the sides of the boxes and fill in the interior with

Building Stairs for Decks - Stairs layout, Stringers and more - DecksGo The landing point is further away from the deck so it may not be the same level as directly below the deck. Take this into consideration. The diagram below illustrates the concept of rises and run nicely. This rise was a convenient 44”. This allowed for 6 rises of exactly 7.33” or about 7 ¼”. Using two 2x6s with a ¼” gap created a stair tread size of about 11 ¼”. To determine the total run we multiplied the run size of ten inches (not the actual tread because we wanted the treads to overhang
Stair Tread NoseSpecifications Building stair tread nosing codes This article discusses how stair tread nose projection should be designed, shaped & sized. Should stair tread nose projections be eliminated? What about open riser stairs?

The International Residential Code (IRC) governs the maximum rise (the height of each step) and the minimum run (the depth of each step), which are 7-3/4 in. and 10 in., respectively. Many jurisdictions, particularly in the Northeast, allow an 8-1/4-in. rise and a 9-in. run. Treads on stairs with a run of less than 11 in. must overhang the riser below by a minimum of 3⁄4 in. and
Cutting Basic Stairs Professional Deck Builder Staircases 20 Sep 2012 for the purpose of figuring out how far a stair jack will project from the deck, add together the depths of all the treads. for example, if a stair has four treads with a tread depth of 10 inches, the bottom face of the stair jacks will be 40 inches out from the deck. To this, you'd also have to add the thickness of one riser, and the amount the bottom tread overhangs the bottom riser, to get the total distance the stair extends. The minimum tread depth — or the length of the level
Building and Installing Deck Stairs Professional Deck Builder 1 Jan 2011 With the landing elevation pinpointed, I measure the total stair rise from the landing finish level to the top of the decking. I always lay a piece of finish decking on top of the joists to measure from; otherwise - if I measure off the deck frame - I might forget to add in the width of the decking. for decks close to the ground, I place a level across the finish decking and just measure down from it to the landing. On tall decks, since my level doesn't reach out far enough, I set a

It's the horizontal distance from the face of one riser to the face of the next riser, or from nosing to nosing, and the other stringer cut—it's NOT the size of the tread itself, which includes a leading edge overhang of ¾” to 1 ¼” (according to the IRC for most On my first stair, r+R was roughly 15 inches—way too far from 18” to be comfortable or safe.
