Can I use 2×10 for stair stringers?
Pressure-treated or cedar 2×10 or 2×12 can be used depending on the depth of the cut-outs you’ll be using. By code you will need a minimum of 3-1/2″ of material left on the stringer after the cut-outs and that area should also be free of large knots which would weaken the stringer.
How do you make a simple stair stringer?
What is the formula for stringers?
There are several formulas for calculating the ratio between rise and run; the simplest is Rise + Run = 17 to 18 inches. Using a target run of 10 inches, the rise/run ratio is well within the “safe and comfortable” formula for this stair: 7 5/8 + 10 = 17 5/8 (Step 6).
Can I use 2×12 for stair treads?
It is acceptable and within building code guidelines to use either 2×10 or 2×12 dimensional lumber to create a set of stairs; however, a stair stringer should not be less than 3.5 inches wide at its narrowest point to provide adequate strength for the load the stairs will be supporting.
What size lumber is used for stair stringers?
The stair stringers are essentially the backbone of your staircase. Always use straight, high-quality, pressure-treated 2x12s for stair stringers. If you are planning on resting the stringer on the ground, make sure the wood has .
How long should a 2×12 stringer be?
How to Use the EZ Stair Calculator. We suggest 10.5″ for 2×12 or 2 – 2×6 Treads. Treads may be cut to suit other widths.
How far apart should stair stringers be?
Deck stairs are typically made from 2 x 12 stringers spaced about 12 to 16 inches apart. They rest on a solid foundation and are attached to the deck with hangers. They have risers (also called toe kicks), treads and railings. The stairs should be at least 36 inches wide.
What is the best wood for stair stringers?
LP SolidStart Laminated Strand Lumber (LSL) and LP SolidStart Laminated Veneer Lumber (LVL) are ideal for Stair Stringers because they surpass traditional lumber products in length, strength and consistency.
How high is a 2 step Stringer?
Size:2 In. Step stringers are cut for 2″ X 12″ Treads, and have a 7″ Rise.
How tall is a 5 step Stringer?
Stair Stringer-5 step Redwood (Common: 60 in. x 11 in.; Actual: 1.5 in.
Can stairs be built without stringers?
A traditional staircase built with stringers can be less than optimal for very wide stairs. Box steps instead are the preferred choice because they are simple and can be built to any length. If your deck is low and requires only a few stairs or even just one, then steps without stringers are the way to go.
What is the code for stair stringers?
Stair stringers should not span more than 13 feet and 3 inches (4039 mm) for a closed stringer. Cut stringers should not span more than 6 feet (1829 mm). Refer to the American Wood Council’s 2018 Prescriptive Residential Wood Deck Construction Guide for stringer spans.
How many steps are in a 4 foot deck?
A four-foot high deck can have a range between 6 and 8 steps.
What is the standard rise and run of stairs?
The OSHA standard for rise and run of stairs is maximum 9.5″ rise and minimum 9.5″ run (tread depth). The IBC maximum rise of a single stair flight is 12.
How do you calculate steps 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).
Can you use joist hangers for stair stringers?
Use joist hangers to fasten the blocking. Pros: Allows for the use of all types of stair stringer hangers. The top of the stair stringer acts as the first tread instead of being flush with the deck’s surface.
Do deck stairs need toe kicks?
The tread (or depth) of your steps should be ten and a half inches. The risers (or toe kick) must be between seven and eight inches high. A handrail is only required if your deck is more than thirty inches off the ground.
How far does tread overhang riser?
The acceptable tread overhang requirements according to the IRC protrude 3/4″ to 1-1/4” past the face of the riser or riser line to ensure the going is 10-inches. The overhang increases the foot placement space on the tread, but doesn’t change the depth of the going, or tread depth under the IRC definition.
Are stairs 45 degrees?
No matter what the measurements are, the angle between them (treads and risers) will be maintained at 90 degrees. For example, if you were crazy and built a staircase with a 12 inch tread and riser, then the angle of the stringer to the floor would be 45 degrees. A more common angle is about 37 degrees.
Can you use deck boards for steps?
Stair treads may be made of a single 2×12, but are often made of two decking boards or 2x6s. A stringer is a wide board, usually a 2×12, that runs at an angle from the landing pad to the deck framing and supports the treads. The stair treads should be at least 36 inches wide.
What size should deck joists be?
Commonly used joist sizes are 2-by-6, 2-by-8 and 2-by-10. For example, when you space joists 16″ apart — which is standard for residential decks — a deck spanning 9 1/2′ would require 2-by-6 joists, a 13′ deck would need 2-by-8 joists and a 16′ deck calls for 2-by-10 joists.
