* Corrosion Resistance: Cedar contains natural oils that can corrode certain metals.
* Nail Strength: Cedar is relatively soft, so you don't need extremely strong nails that could split the wood.
* Appearance: If the nails will be visible, you'll want to consider the color and finish.
Given these factors, here are the best nail options for Western Red Cedar:
* Stainless Steel Nails: These are the best choice overall. Stainless steel is highly corrosion-resistant and won't react with the cedar oils. They are more expensive but provide excellent long-term performance and prevent unsightly staining. Type 304 or 316 stainless steel is suitable.
* Aluminum Nails: Another good option for corrosion resistance. Aluminum is softer than steel, so it's less likely to split the cedar. Be mindful of strength if using for structural applications.
Nails to Avoid (or use with caution):
* Galvanized Steel Nails: Hot-dipped galvanized nails are *acceptable* for some cedar applications, but stainless steel is preferable. The galvanization provides a protective layer, but it can still corrode over time, especially in damp or coastal environments. If using galvanized, make sure it's a heavy, hot-dipped coating. *Electro-galvanized nails are NOT recommended* due to the thin coating that will corrode quickly.
* Common Steel Nails: These will rust quickly and are unsuitable for cedar. They will cause staining and weaken the connection.
Important Considerations for Choosing the Right Nail:
* Project Type:
* Exterior Siding, Fencing, or Decking: Stainless steel nails are highly recommended for optimal weather resistance and longevity.
* Interior Trim: Galvanized or stainless steel will both work, but stainless steel is preferred for its appearance and resistance to any potential staining.
* Small Craft Projects: Depending on the exposure to the elements, you may get away with a lighter gauge galvanized nail.
* Nail Size: Choose the appropriate length and gauge based on the thickness of the cedar and the load it will bear.
* Nail Type:
* Ring Shank Nails: Offer superior holding power, especially in softer wood like cedar. Good for siding and decking.
* Smooth Shank Nails: Easier to drive but have less holding power. Can be suitable for trim.
* Spiral Shank Nails: Offer more holding power than smooth, but less than ring shank.
In summary:
For the best results and longevity, stainless steel nails are the top recommendation for Western Red Cedar. They offer excellent corrosion resistance and prevent unsightly staining. Aluminum nails are a secondary acceptable option. Avoid common steel nails and be cautious with galvanized steel, opting for heavy hot-dipped galvanization if used. Always consider the specific project and environmental conditions when making your final decision.
