Do deck stair stringers need support?

Stringers typically have two bearing points, with the plumb (vertical) cut bearing on a rim joist or on a beam, and the seat (horizontal) cut bearing on—at minimum—a solid landing. To help resist both vertical and lateral loads, stringers require proper support and attachment at these bearing points.

Can I use 2×8 for stair stringers?

Can you put 2 stair stringers together?

Both visually and structurally, it is preferable to break long stair runs with intermediate landings. You also may consider doubling your stair stringers by nailing two 2x12s together like a beam in order to increase strength. Adding blocking between stringers also can strengthen the entire stair structure.

Do deck stairs have to land on concrete?

Stair landings must be at least as wide as the stair and at least 3 feet deep. On the other hand, solid, flat, and stable materials, such as concrete, flagstone, pavers, or brick, can be installed with a measurable slope and will not usually shift under the weight of an off-balance person completing a stairway descent.

How do you calculate stairs for a deck?

To determine the rise and run of the steps, measure the distance from the floor of the deck to the ground and divide that number by 7.5. The result will be the number of steps the staircase will need (e.g., deck is 112″ from the ground; 112/7.5 = 14.93. Round up to get 15 steps).

How do you cut stair stringers accurately?

The solution is simple – shorten the bottom riser cut on the stringer by the tread thickness. So, that cut where the stringer meets the bottom landing would be 5 ¼ inches from the tread above, while all the other risers would remain at 6 ¼ inches.
