Redwood fasteners are widely available, giving you many options when you are ready to start building with redwood lumber. Whether you are building a redwood deck, fence, planter box, trellis, arbor, or other garden structure, choosing the proper fastener is an essential part of any outdoor living project. Nails and screws work well for a variety of projects where surface appearance is of secondary concern (fencing, landscaping, garden projects). Hidden fastener systems are increasingly popular for projects where surface appearance is very important, such as for redwood decks.
The rule of thumb for redwood fasteners is to only use ones that are non-corrosive. The best options are stainless steel, aluminum, or top-quality, hot-dipped galvanized fasteners. Lower quality, electro-plated galvanized fasteners are not recommended. Lower quality fasteners will cause unsightly stains on your new redwood deck, fence, or garden structure, and should be avoided. The reason is because these types of fasteners will react with redwood’s natural, decay resisting extractives, which will cause staining. Other types of coated fasteners are also not recommended as the coating may wear off over time.
