Choosing the right outdoor table material for a screened gazebo with underfloor heating requires balancing durability, weather resistance, and heat compatibility. Here are the top options:

1. Teak: Naturally weather-resistant and durable, teak withstands moisture and temperature fluctuations. Its low thermal conductivity makes it ideal for underfloor heating.

2. Powder-Coated Aluminum: Lightweight and rust-proof, aluminum with a powder-coated finish resists heat damage and maintains its appearance over time.

3. Stainless Steel: Highly durable and heat-resistant, stainless steel is perfect for modern gazebos but may require cushions for comfort.

4. Polywood: A synthetic material mimicking wood, Polywood is UV-resistant, low-maintenance, and unaffected by underfloor heating.

5. Concrete: For a sturdy, heat-retentive option, concrete tables with sealed surfaces prevent cracking and moisture absorption.

Consider your climate and design preferences to select the best material for longevity and comfort in your screened gazebo.
