What are the flammability ratings of WPC outdoor chairs in fire-prone areas?
WPC (Wood-Plastic Composite) outdoor chairs are popular for their durability and low maintenance, but their flammability ratings are crucial for use in fire-prone areas. Typically, WPC materials have moderate flammability due to their plastic content, but additives can improve fire resistance. Look for chairs rated Class B or higher under ASTM E84 or similar standards, indicating slower flame spread. For high-risk zones, opt for WPC with fire-retardant treatments or metal/stone alternatives. Always check local fire safety regulations to ensure compliance. Proper spacing and non-combustible bases can further enhance safety. Choosing fire-resistant WPC outdoor chairs helps balance aesthetics and safety in vulnerable environments.
