4. Specifications

Text Description for Figure 4.1: This diagram illustrates the key dimensions of a single two-step metal stair stringer. It shows an overall height of 19.4 inches, a total length of 20.5 inches, and individual step dimensions. The top step has a rise of 5.8 inches and a run of 10.1 inches. The bottom step has a rise of 7.5 inches and a run of 10.1 inches. The vertical support measures 13.6 inches from the ground to the top of the lower step bracket, and 6.1 inches from the ground to the bottom of the lower step bracket.

Text Description for Figure 4.2: This image highlights the construction quality of the stringer. It shows a close-up of the 90-degree one-piece molding for the step brackets, indicating a strong, seamless design. A caliper measurement confirms the iron plate thickness of 3.5mm, emphasizing the robust build.

5. Setup and Installation

Follow these steps to install your yeezoo 2-Step Metal Stair Stringers:

1. Prepare the Ground/Base: Ensure the ground where the stringers will rest is level and stable. For uneven surfaces, consider adding gravel, bricks, or cement blocks to create a level foundation. This is crucial for the stability and safety of your stairs.
2. Position the Stringers: Place the two metal stringers in the desired location, ensuring they are parallel and spaced appropriately for your chosen tread width. The stringers are designed for a 19.4-inch height deck.
3. Mark Fixing Points: Hold the stringers against the deck or wall. Use a level to ensure the stringers are perfectly level both front-to-back and side-to-side. Mark the pre-drilled holes on the stringer's vertical support onto your deck or wall.
4. Secure to Deck/Wall:
   • For Wooden Decks: Use lag bolts (not included) to securely fasten the stringers to the side of the wooden deck through the pre-drilled holes.
   • For Concrete/Masonry: Use the provided expansion screws. Drill holes at the marked points using the included drill bit. Insert the expansion screws and tighten them with the provided wrench to firmly secure the stringers to the concrete surface.
5. Prepare Treads: Cut your chosen wooden treads to a width of 10.1 inches or slightly wider. Ensure the length is appropriate for the desired width of your staircase.
6. Attach Treads: Place the treads onto the step brackets of the stringers. The stringers feature four pre-drilled holes per step bracket for securing the treads. These holes are strategically placed to facilitate screwing from underneath. Use the provided tapping screws to fasten the treads securely to the stringers. You may need specialized tools to access and tighten screws from underneath due to the hole placement.
7. Final Check: Once all treads are attached, re-check the stability of the entire staircase. Ensure all screws are tight and the stairs are level and secure before use.

Text Description for Figure 5.1: This image illustrates the placement and size of the pre-drilled holes on the metal stair stringer. It shows two 1/3-inch diameter holes at the top for fixing the stringer to a deck or wall, and one 1/3-inch diameter hole at the bottom for securing the riser to the ground. Additionally, there are four 0.27-inch diameter holes on each step bracket for attaching wooden treads, with two rows of two holes for easier access.

Text Description for Figure 5.2: This image provides a visual guide to the installation process. It shows the two metal stringers mounted to a wall or deck, with wooden treads attached. Callouts indicate the included tapping screws for treads and expansion screws for mounting to a solid surface. It also explicitly states that bolts for securing to a wooden deck are not included.

6. Operating and Usage

Once properly installed, your yeezoo 2-Step Metal Stair Stringers provide a stable and durable access solution. These stairs are suitable for a variety of outdoor and indoor environments:

• Deck Access: Provides convenient entry and exit from elevated decks.
• Hot Tub Steps: Offers safe and easy access to hot tubs or spas.
• Porch Entry: Creates a functional two-step entry for porches or elevated doorways.
• Garden/Yard Access: Facilitates movement between different levels in your garden or backyard.

Text Description for Figure 6.1: This collage demonstrates the versatility of the yeezoo 2-step metal stair stringers. It shows four different usage scenarios: a set of stairs leading up to a house door, stairs providing access to an elevated wooden deck, steps positioned next to a hot tub for easy entry, and stairs descending from a deck to the ground level. These examples highlight the product's adaptability for various outdoor access needs.

7. Maintenance

To ensure the longevity and continued performance of your metal stair stringers, follow these maintenance guidelines:

• Regular Cleaning: Clean the metal stringers periodically with a mild soap and water solution. Rinse thoroughly and dry to prevent water spots or mineral buildup. Avoid abrasive cleaners or harsh chemicals that could damage the powder coating.
• Inspect Fasteners: Annually, or more frequently in high-traffic areas, inspect all screws and bolts for tightness. Re-tighten any loose fasteners to maintain structural integrity.
• Check for Damage: Periodically inspect the stringers for any signs of rust, chips in the powder coating, or structural damage. Address any issues promptly to prevent further deterioration. The 3-layer black powder coating is designed for both interior and exterior use and provides excellent protection against the elements.
• Tread Condition: If using wooden treads, inspect them for rot, splinters, or instability. Replace damaged treads as necessary.

8. Troubleshooting

If you encounter issues during or after installation, refer to the following common problems and solutions:

• Stairs feel wobbly or unstable:
  • Ensure the ground or base beneath the stringers is perfectly level. Adjust with shims or additional leveling material if needed.
  • Verify that all fasteners securing the stringers to the deck/wall and the treads to the stringers are fully tightened.
  • Confirm the stringers are parallel and correctly spaced.
• Difficulty attaching treads due to screw access:
  • The pre-drilled holes are designed for screwing from underneath. Using a right-angle drill attachment or a flexible shaft driver may provide easier access.
  • Ensure pilot holes are drilled into the wooden treads before attempting to drive screws, especially if using harder wood.
• Stringer appears bent or damaged upon arrival:
  • Inspect the packaging for signs of damage.
  • If a stringer is significantly bent and cannot be straightened without compromising its integrity, contact customer support for assistance.
