Buying Guide: Selecting The Right Stringer For Ground-Contact Pine Projects
- Material and Finish: For ground-contact and pine environments, corrosion resistance is crucial. Powder-coated steel is a common choice for outdoor durability, while galvanized steel offers robust protection against moisture and soil exposure. Avoid untreated metal in ground-contact scenarios.
- Step Count And Height: Align the stringer’s step count with your deck or stair height. Higher heights may require 8-step configurations; keep in mind the recommended spacing between stringers (often ≤ 3 feet).
- Attachment Hardware: Look for a package that includes pre-drilled holes and hardware for secure mounting to wooden treads or concrete walls. Ensure you have compatible fasteners for pine framing and ground contact.
- Installation Kit Content: Some sets include complete installation kits with screws, set screws, and expansion anchors. If not, plan to source these separately to ensure a solid anchor in porch or deck frames.
- Wood Tread Compatibility: Many stringers are sold without wooden treads. Verify tread dimensions and choose stringers that support your chosen pine boards or treat panels.
- Weather and Longevity: For pine-adjacent projects, choose products with rust-resistant finishes to protect both metal and surrounding wooden components from moisture and decay.
