What are the best materials for landscape tables in areas with high sulfur dioxide exposure?

When selecting materials for landscape tables in areas with high sulfur dioxide (SO₂) exposure, durability and corrosion resistance are critical. Sulfur dioxide, a common air pollutant, can accelerate material degradation, especially in outdoor settings. Here are the top materials to consider:

1. Stainless Steel (Grade 316): Known for its exceptional corrosion resistance, 316 stainless steel contains molybdenum, which enhances its ability to withstand sulfur dioxide and other harsh environmental factors.

2. Powder-Coated Aluminum: Lightweight yet robust, aluminum with a high-quality powder coating provides an extra layer of protection against SO₂-induced corrosion.

3. Marine-Grade Polymer: Materials like high-density polyethylene (HDPE) or recycled plastics are immune to rust and corrosion, making them ideal for sulfur-rich environments.

4. Teak Wood: Naturally resistant to moisture and pollutants, teak is a premium choice for outdoor furniture, though it requires periodic maintenance.

5. Concrete with Sealant: Sealed concrete tables offer durability and resistance to chemical erosion, but the sealant must be reapplied periodically.

For longevity, prioritize materials with minimal maintenance needs and proven resistance to sulfur dioxide. Regular cleaning and protective coatings can further extend the life of your landscape tables in polluted areas.
