Here's a step-by-step guide on how to install composite decking on stairs:

Materials Needed:

  1. Composite decking boards

  2. Aluminum joist

  3. Adjustable pedestals for height adjustment

  4. Screws and clips

  5. Tape measure

  6. Level

  7. Saw (for cutting)

Installation Steps:

1. Measure and Plan:

  • Begin by measuring the dimensions of your stairs to determine the number of composite boards and aluminum stringers needed.

  • Plan the layout, considering the direction of the boards and the spacing.

2. Prepare the Stair Stringers:

  • Place the aluminum stair joist at the desired locations on your stairs.

  • Ensure they are level and securely fasten them to the existing structure.

3. Install Adjustable Pedestals:

  • If your stairs require height adjustments, install adjustable pedestals under the aluminum joist. This is crucial for maintaining a level surface, especially on uneven terrain.

4. Cut MexyTech Composite Decking Boards:

  • Use a saw to cut the composite decking boards to the required lengths for each stair tread.

  • Ensure precise cuts for a clean and professional finish.

5. Attach Composite Boards:

  • Begin attaching the composite boards to the stair stringers using clips.

  • Use the recommended spacing to allow for proper drainage and expansion of the boards.

6. Check for Level and Alignment:

  • Regularly check for level and alignment as you progress.

  • Adjust the adjustable pedestals if necessary to maintain a consistent level across all steps.

7. Complete the Installation:

  • Continue attaching the composite boards until you reach the top of the stairs.

  • Double-check all screws and fastenings for security.

8. Finishing Touches:

  • Consider adding fascia boards to conceal the edges of the composite decking for a polished look.

  • Trim any excess material for a clean and finished appearance.

9. Maintenance Tips:

  • Composite decking requires minimal maintenance, but periodic cleaning is recommended to preserve its appearance.

  • Use a mild detergent and a soft brush to clean the surface.

Conclusion:Elevate the aesthetics of your outdoor staircase with the durability and modern appeal of composite decking. Our aluminum joist, co-extrusion wood-plastic boards, and adjustable pedestals provide a versatile solution for a sleek and long-lasting stair design.
