What are the fire ratings for stone, granite, and marble outdoor bar stools?

When selecting outdoor bar stools, understanding fire ratings is crucial for safety and longevity. Stone, granite, and marble are popular materials, but their fire resistance varies.

Stone Bar Stools: Natural stone is generally non-combustible and has a high fire rating, making it a safe choice for outdoor use. However, prolonged exposure to extreme heat may cause cracking.

Granite Bar Stools: Granite is highly fire-resistant, often classified as Class A (the highest rating). It can withstand high temperatures without damage, ideal for outdoor settings near fire pits or grills.

Marble Bar Stools: While marble is also non-combustible, it has a lower heat tolerance compared to granite. Direct flames or intense heat may cause discoloration or structural weakening over time.

For optimal safety, choose materials with high fire ratings like granite for areas prone to heat exposure. Always verify fire ratings with manufacturers to ensure compliance with local safety standards.
