When selecting outdoor seating for environments with strong magnetic fields, choosing the right materials is crucial to ensure durability, safety, and minimal electromagnetic interference. The best options include:

1. Aluminum: Lightweight, corrosion-resistant, and non-magnetic, aluminum is ideal for outdoor furniture in high-magnetic environments. Its durability makes it suitable for long-term use.

2. Stainless Steel (Austenitic Grades): While most steels are magnetic, austenitic stainless steels (e.g., 304 or 316) are non-magnetic and highly resistant to rust, making them perfect for outdoor settings.

3. Plastic (HDPE or Polypropylene): These synthetic materials are entirely non-magnetic, weather-resistant, and easy to maintain. They’re also lightweight and affordable.

4. Wood: Naturally non-magnetic, wood offers a classic aesthetic but requires regular maintenance to withstand outdoor conditions. Teak and cedar are excellent choices.

5. Fiberglass: Strong, lightweight, and immune to magnetic fields, fiberglass is another great option for outdoor seating in challenging environments.

Avoid ferrous metals like iron or carbon steel, as they can interfere with magnetic fields and corrode quickly. Prioritize materials that combine non-magnetic properties with weather resistance for optimal performance.
