Step 2 · Select Materials for Steps
Select lumber for the main structure (stringers, treads, risers). Pressure-treated lumber is recommended for outdoor use due to its resistance to rot and insects. Cedar or redwood are also good, naturally resistant options but are more expensive. Decide on the type and size of fasteners (e.g., deck screws, galvanized or stainless steel bolts) that will resist corrosion. If painting or staining, select appropriate exterior-grade products.
