What Are Simpson Strong-Tie Stair Stringers?
Before diving into the installation process, it’s important to understand what Simpson Strong-Tie stair stringers are. These are metal connectors designed to reinforce wooden stair stringers, ensuring they remain strong and stable over time. They are particularly useful in outdoor stair projects, such as decks or exterior staircases, where wood is exposed to the elements and needs extra support.
Tools and Materials You’ll Need
Before you begin, gather the following tools and materials:
- Simpson Strong-Tie stair stringers
- Pressure-treated lumber (for the stringers)
- Measuring tape
- Carpenter’s square
- Circular saw or handsaw
- Drill with bits
- Simpson Strong-Tie connectors (varies based on the project)
- Galvanized screws or nails
- Level
- Safety glasses and gloves
How to Install Simpson Strong-Tie Stair Stringer
Now that you have everything ready, let’s get into the step-by-step process of installing your Simpson Strong-Tie stair stringers.
Step 1: Measure and Cut the Stringers
The first step in installing Simpson Strong-Tie stair stringers is measuring and cutting your wooden stringers.
- Measure the rise and run: Determine the total rise (height) and run (depth) of your stairs. These measurements will guide you in cutting your stringers accurately.
- Mark the stringers: Using a carpenter’s square, mark the rise and run on your pressure-treated lumber. Ensure that the cuts are accurate and consistent to avoid uneven steps.
- Cut the stringers: Use a circular saw to make the cuts along the marked lines. If necessary, finish the cuts with a handsaw for precision.
- Check the fit: Place the stringers in their intended location to ensure they fit properly. Make any adjustments if necessary.
Step 2: Attach the Simpson Strong-Tie Stair Stringers
With your wooden stringers cut and ready, it’s time to attach the Simpson Strong-Tie stair stringers.
- Position the connectors: Place the Simpson Strong-Tie connectors at the top and bottom of each wooden stringer. These connectors will secure the stringers to the framing of your deck or structure.
- Pre-drill holes: To prevent splitting, pre-drill holes where you’ll be inserting screws or nails. Make sure the holes are aligned with the pre-punched holes in the Simpson Strong-Tie connectors.
- Secure the connectors: Using galvanized screws or nails, secure the Simpson Strong-Tie connectors to the stringers. It’s crucial to use galvanized hardware to prevent rust and ensure longevity, especially in outdoor settings.
- Attach the stringers to the framing: Once the connectors are secured to the stringers, attach the stringers to the framing of your deck or structure. Use a level to ensure the stringers are perfectly aligned and secure them tightly.
Step 3: Install the Treads and Risers
With the stringers securely attached, it’s time to install the treads (the horizontal part of the stairs) and risers (the vertical part).
- Measure and cut the treads and risers: Using your earlier measurements, cut the treads and risers to size. Ensure each piece fits snugly between the stringers.
- Attach the risers: Begin by attaching the risers to the stringers. Secure them using screws or nails, ensuring they are flush with the front edge of the stringers.
- Install the treads: Next, place the treads on top of the stringers. Secure them with screws or nails, making sure they are level and firmly attached.
- Check alignment: Once all the treads and risers are installed, double-check the alignment of the stairs using a level. Make any necessary adjustments to ensure the stairs are safe and even.
Step 4: Inspect and Finish
After installing the treads and risers, it’s important to inspect the entire staircase for stability and finish.
- Inspect the structure: Walk up and down the stairs to ensure they feel stable and secure. Check that all screws and nails are tight, and that there is no wobbling.
- Finish the stairs: If you’re installing outdoor stairs, consider applying a weather-resistant finish to protect the wood from the elements. This will extend the life of your stairs and keep them looking good.
