How To Build Deck Stair Railing

What is code for deck stair railing?

Stair rails on decks should be between 34 inches and 38 inches high, measured vertically from the nose of the tread to the top of the rail.

The IRC specifies that deck stair railing should measure between 34 and 38 inches high, so homeowners may wish to use railing that is even higher than 34 inches for their deck stairs.

How do you calculate the angle of a handrail?

Set your calculator to calculate trigonometric functions in degrees. Divide the total rise by the total run of the staircase. Then calculate the inverse tangent of the result. The answer is the angle the staircase makes at the bottom, and it will be the angle at which your railing rises.

Do I need a railing on both sides of deck stairs?

You don’t need a handrail on both sides, but you may need a railing if your deck is higher than 30″. Many contractors construct a combo handrail and stair rail system, installed on both sides, to cover all safety requirements.

Can I use joist hangers for stair stringers?

This will reinforce the stair stringer to rim joist connection and distribute the stair weight more evenly onto the deck framing. Cut them to fit the space perpendicularly between the rim joist and the next interior joist. Use joist hangers to fasten the blocking.

How do you attach wood stair stringers to a deck?

Attach the stringers to the deck using angle brackets and 3” galvanized deck screws. Cut a 2×6 board to fit snugly between the two stringers at their base. This will be used to fasten the stairs to the concrete pad. Place the board between the stringers and attach to stringers with 3” galvanized deck screws.

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 code height for stair railing?

Handrail height on the stairs should be no less than 34 inches and no greater than 38 inches. The way this is measured is to begin at the leading edge of the stair nosing and run an imaginary vertical line upward until it reaches the top of the railing.

Does deck railing need to be pressure treated?

As long as there’s a good chance that moisture can reach the wood, it should be pressure treated. This is why the International Building Code requires that siding and structural lumber used for the last six inches of the structure above the ground is pressure treated.

Can I use a 2×4 for a handrail?

According to the IRC (2018), you can use a 2×4 to make a handrail, but you must cut finger recesses along both sides of the board and position the lumber lengthwise on its end. Using a 2×4 as a handrail laid vertically is not allowed. Porch and deck guardrails made from 2x4s laid horizontally are permitted.

How do you measure for an outdoor stair railing?

5 Easy Steps For Measuring Step 1 – Measure the overall height. Step 2 – Measure the overall length. Step 3 – Length of nosing. Step 4 – Depth of finished tread. Step 5 – Height of finished tread.

What is the difference between a handrail and a stair rail?

Handrails and stair railings – they sound like pretty much the same thing. They’re not. A stair railing, on the other hand, is mostly to prevent people from falling off the side of the stairs. They aren’t asked to do much more – and they don’t.

How do I calculate stair railing?

Try to measure within a 1/6 of an inch for best results. Step 1: Measure the Tread Rise. Step 2: Count the Number of Rises. Step 3: Measure the Tread Run. Step 4: Measure the Tread Thickness. Step 5: Measure the Nose Projections. Step 6: Calculate the Stair Angle and Double-Check Your Dimensions.

What type of wood is used for deck railings?

Budget friendly deck rails are generally wood, usually pressure treated lumber, cedar or pine. The materials are inexpensive to buy and install but wood rails do come with increased maintenance costs.
