What are the fire resistance ratings for different materials used in landscape tables?

When selecting materials for landscape tables, understanding their fire resistance ratings is crucial for safety and compliance. Different materials exhibit varying levels of flammability and resistance to fire, which can significantly impact their suitability for outdoor use.

1. Wood: Natural wood is generally combustible, but treated options like pressure-treated lumber or fire-retardant-coated wood can achieve Class B or Class A ratings. Hardwoods like oak or teak have higher natural resistance compared to softwoods.

2. Metal: Aluminum and steel are non-combustible, often achieving the highest fire resistance ratings (Class A). However, coatings or paints may affect performance, so selecting fire-resistant finishes is essential.

3. Plastic/Composite: Most plastics are highly flammable (Class C or lower), but composite materials with fire-retardant additives can meet Class B standards. Look for UL-certified composites for assured safety.

4. Concrete/Stone: These materials are inherently fireproof (Class A), making them ideal for high-risk areas. Their durability and resistance to heat make them a top choice for public spaces.

5. Wicker/Rattan: Synthetic wicker with flame-retardant treatments can achieve Class B ratings, while natural fibers are typically more flammable.

Always verify local fire safety regulations and opt for materials with certified fire resistance ratings to ensure longevity and safety in outdoor settings.
