When selecting outdoor furniture for areas prone to acid fog, durability and resistance to corrosion are paramount. Acid fog, often caused by industrial pollution or volcanic activity, can accelerate the deterioration of materials. Here are the top choices for long-lasting outdoor furniture in such harsh conditions:

1. Aluminum: Powder-coated or anodized aluminum is highly resistant to rust and corrosion, making it ideal for acid fog environments. Its lightweight nature and low maintenance add to its appeal.

2. Stainless Steel: Opt for marine-grade stainless steel (316 grade), which contains molybdenum for enhanced resistance to acidic conditions. Regular cleaning prevents surface damage.

3. Synthetic Resin (Polyethylene/Rattan): High-density polyethylene (HDPE) or synthetic rattan is non-porous, UV-resistant, and unaffected by moisture or acidic exposure. It mimics natural aesthetics without the upkeep.

4. Teak: Naturally oily teak wood resists moisture and acid fog well, though periodic sealing is recommended to prolong its lifespan.

5. Powder-Coated Steel: Ensure the coating is thick and high-quality to prevent chipping and exposure to corrosive elements.

Avoid materials like untreated iron, low-grade steel, or delicate fabrics, as they degrade quickly in acidic conditions. Regular maintenance, such as rinsing off acidic deposits, further extends furniture longevity. Choose wisely to balance aesthetics and resilience in acid fog-prone regions.
