Do you need a stringer for stairs?

You’ll need at least one stringer for every 16 inches of stair width. If you’re using synthetic decking for the treads, some manufacturers require stringers to be spaced no more than 12 inches apart.

What are other names for a stair stringer?

Stringer. A supporting member running the length of an incline stair on which treads and risers are mounted. Also called carriage or stair horse.

What do you use for stair stringers?

Most stairbuilders use dimensional lumber for stair framing, but if you want super strong and straight stringers, consider making them out of engineered lumber. 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.

What is a riser and stringer?

A stair stringer is built to support the staircase, either from the bottom or from the sides. As you learned above, an open riser staircase is simply a stairway that removes the risers between each step. Typically, open riser staircases use mono or double stringers to support their structure.

What size board do I need to make a stair stringer?

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 . 60 RET level.

Can I use 2×10 to make stair stringers?

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.

How many stair stringers do I need for my staircase?

If you’re stairway is between 30 and 36 inches you will need three stair stringers. How many stair stringers you actually need will also be determined by the thickness of your stair treads.

How to calculate stair stringers?

Start by finding the overall height that the staircase will be.

Decide the height or “rise” you’ll want for each step. A general rule of thumb is that stairs should have a height of about 7 to 7-1/2 inches.

Divide the total height of the staircase by the height or “rise” you want for each step. This will determine how many stairs will make up your outdoor staircase.

Run that formula again,however,divide the total height of the staircase now by the total number of steps. Do not round the measurement at all.

Determine how deep you want your steps to be and multiply that distance by the number of steps you’ll have.

Lastly,with all of the dimensions in hand,sketch out your stair plans to get a clear vision for your stringer boards.

What are you using for stair stringers?

Stair stringers are most often cut from a single 2×12 stock board. Situate the tread arm of the square nearest to the end of the board. The tread arm is the one you’re using to indicate the run of the steps, while the riser arm will serve as a guide for marking the rise.

How to calculate stair stringer length?

Measure the height from the surface where the stairs will start to the bottom surface that the stairs will connect to.

Divide the height of the staircase in inches by the intended rise of each step,also in inches,to assist in determining the stair stringer length.

Round up the number you receive from the calculation in the previous step.
