Absolutely. For high-risk areas like wildfire-prone zones, industrial sites, or public spaces requiring stringent fire safety, specifying fire-retardant outdoor benches is a critical consideration. While no outdoor material is entirely "fireproof," several options significantly resist ignition, slow flame spread, and are classified as non-combustible or fire-retardant.
The primary choice is metal. Benches constructed from heavy-gauge aluminum, steel, or cast iron are inherently non-combustible. For enhanced protection, look for models with powder-coated finishes that include intumescent properties. This coating swells when exposed to high heat, forming an insulating char layer that protects the underlying material.
Another robust solution is concrete or composite concrete benches. These materials offer excellent inherent fire resistance and durability. Modern composites can mimic the look of wood without the flammability.
For a wood-like aesthetic, specify engineered fire-retardant treated (FRT) wood or Class A fire-rated high-density polyethylene (HDPE) lumber. These materials undergo treatment or are manufactured to meet strict flame spread and smoke development indices (like ASTM E84). Crucially, ensure any selected product is tested and certified by recognized bodies such as UL (Underwriters Laboratories) or meets relevant ASTM International standards for outdoor exposure.
Key features to prioritize include minimal crevices where embers can lodge, non-combustible hardware, and designs that avoid plastic components that can melt. Regular maintenance to clear away dry debris like leaves is also essential for sustained safety.
Ultimately, investing in certified fire-retardant benches mitigates risk, protects infrastructure, and provides crucial safety in vulnerable locations. Consult with manufacturers to review specific test reports and warranties for your application's environmental conditions.
