What are the best wood types for outdoor sofa frames in areas with acid rain?

When selecting wood for outdoor sofa frames in areas with acid rain, durability and resistance to moisture and corrosion are critical. The best wood types include:

1. Teak: Naturally resistant to water, insects, and decay due to its high oil content, making it ideal for harsh weather conditions.

2. Cedar: Contains natural tannins and oils that repel moisture and pests, ensuring longevity even in acidic environments.

3. Redwood: Known for its stability and resistance to rot, redwood is a premium choice for outdoor furniture.

4. Ipe (Brazilian Walnut): Extremely dense and durable, ipe withstands acid rain and heavy weathering with minimal maintenance.

5. White Oak: Treated with a water-resistant finish, white oak offers excellent durability against acid rain damage.

For optimal performance, apply a protective sealant annually to enhance the wood's resistance. Choosing these materials ensures your outdoor sofa remains sturdy and beautiful despite acidic conditions.
