Buying Guide: Key Considerations For Selecting Pre-Cut Stair Stringers

What deck height and step count will you build?

Measure the deck height and determine the total number of steps. Choose a stringer option that matches the target rise per step and provides enough steps to reach the desired deck surface safely.

What material and finish matter for outdoor use?

Look for steel with a corrosion-resistant powder-coated finish. This improves longevity against rain, humidity, and sun exposure. Ensure the gauge and bracket thickness support your anticipated load.

Are installation kits included?

Prefer products with pre-drilled holes and included mounting hardware. Aluminum or steel stringers with bolt holes simplify anchoring to concrete or wooden treads. Note if wooden treads are included or required separately.

How important is load capacity and safety?

Check stated load capacity and ensure it exceeds the expected people and equipment load. For outdoor stairs near entryways or hot tubs, plan for higher stability and a secure mounting system.

What space and alignment considerations apply?

Maintain proper spacing between two stringers—typically no more than 3 feet apart—and position the first tread a specific distance below the deck to ensure level, even footing.

What are potential limitations to watch for?

Be prepared for limitations such as the need for separate treads, precise height calculations, or additional hardware. Verify the fit with your exact deck height, railing, and ground conditions before ordering.

What installation skill level is needed?

These premade stringers are designed for DIY use, but accurate measurement and alignment are essential. If you’re unsure, consult a professional to ensure safety and proper installation.

FAQ: Quick Answers For Pre-Cut Stair Stringers

How many stringers do I need for a deck staircase? Answer: Most installations require two stringers, one on each side, but follow the product’s guidance based on step count and span.

Can I install stringers on concrete? Answer: Yes, if the kit includes concrete mounting hardware or you use appropriate anchors and screws designed for concrete surfaces.

Do I need wooden treads? Answer: Some kits include only stringers; wooden treads are often not included and must be sourced separately.

What safety checks should I perform after installation? Answer: Verify bolt tightness, ensure tread alignment is even, and confirm the structure bears weight evenly without wobble.
