Aluminum Fire-Resistant Fence Systems
ASTM E84 Class A Performance | Non-Combustible Protection | Built for Fire-Prone Environments
In regions exposed to wildfire risk, high heat, and evolving building code requirements, material selection is critical. Choosing the right fire-resistant fence is no longer optional: it's a specification driver.
SLEEKFENCE aluminum fencing is engineered for these conditions. As a non-combustible system with an ASTM E84 Class A fire rating, it delivers high-performance fire resistance without contributing fuel to flame spread.
This page outlines what that rating means and why it matters for architects, developers, and property owners designing for fire resilience.
What is ASTM E84?
Understanding Flame Spread & Smoke Development Ratings
ASTM E84 (also known as the Steiner Tunnel Test) is the industry-standard method used to evaluate how materials behave when exposed to fire.
It measures two key performance indicators:
• Flame Spread Index (FSI) – How quickly flames travel across a material’s surface
• Smoke Developed Index (SDI) – The amount of smoke generated during exposure
Materials are then classified:
• Class A (or Class I): Lowest flame spread and smoke development
• Class B
• Class C
SLEEKFENCE achieves a Class A rating, meaning it offers the highest level of resistance to flame propagation and smoke generation under ASTM E84 testing conditions.
Why it matters: Materials with a Class A rating help limit fire growth, reduce smoke hazards, and support safer building envelope design, especially in wildfire interface zones (WUI) and dense urban environments.
Non-Combustible By Design
Aluminum That Won’t Ignite, Fuel, or Accelerate Fire
SLEEKFENCE is manufactured from architectural-grade aluminum, a non-combustible material.
This means:
• It does not ignite when exposed to flame or high heat
• It does not contribute fuel to a fire
• It does not sustain combustion once the heat source is removed
Among fire-resistant fence materials, aluminum stands apart. Unlike wood or composite systems, SLEEKFENCE acts as a passive barrier, not a fire load.
This non-combustible fence construction makes it particularly valuable for:
• Wildland-Urban Interface (WUI) applications
• Perimeter fencing in fire-prone regions
• Commercial and multi-family developments with fire code considerations
• Infrastructure and utility projects requiring resilient materials
Designed For Fire-Prone Environments
Performance That Supports Long-Term Risk Reduction
Fire-resistant design is about more than compliance: it's about reducing risk across the entire property.
SLEEKFENCE supports this by offering:
• Consistent fire performance across all system components
• Durability under extreme heat exposure
• No degradation into combustible debris
• Low maintenance lifecycle performance compared to organic materials
For projects where wildfire exposure, insurance requirements, or municipal codes are factors, specifying a fire-resistant privacy fence that delivers ember-resistant fencing performance is a strategic decision, not just a material upgrade.
Conclusion
Fire Resistance Without Compromise
Fire safety is a defining factor in modern exterior design, especially across North America's expanding fire-prone regions.
With its ASTM E84 Class A rating and non-combustible aluminum construction, SLEEKFENCE provides a fire-resistant fence solution that:
• Resists flame spread
• Minimizes smoke development
• Does not contribute to fire load
Whether you're designing for compliance, resilience, or long-term asset protection, SLEEKFENCE is engineered to perform.

Frequently Asked Questions
Is SLEEKFENCE truly non-combustible?
Yes. Aluminum is inherently non-combustible, meaning it will not ignite or burn under normal fire exposure conditions.
What does a Class A fire rating actually mean?
A Class A rating (ASTM E84) indicates the lowest flame spread and smoke development values achievable in the test, making it the highest classification for surface-burning characteristics.
Will the fence melt in a fire?
What SLEEKFENCE offers is non-combustible aluminum construction with an ASTM E84 Class A fire rating, meaning it will not ignite or contribute fuel to a fire. Aluminum has a melting point of approximately 660°C / 1220°F. While extreme, prolonged exposure can cause deformation, it will not burn or accelerate flame spread.
Does this meet Wildland-Urban Interface (WUI) requirements?
Non-combustible materials like aluminum are commonly specified in WUI zones. However, requirements vary by jurisdiction. Always confirm with local codes and authorities.
How does aluminum compare to wood or composite fencing in a fire?
Wood and many composites are combustible and can accelerate fire spread. Aluminum does not burn, making it a significantly safer choice in fire-prone environments.
Does powder coating affect fire performance?
Powder coatings may degrade under extreme heat, but they do not change the non-combustible nature of the aluminum substrate.
Is fire-rated fencing required for my project?
It depends on your location, building type, and proximity to fire-prone areas. Many jurisdictions are increasing fire performance requirements, especially in WUI zones and commercial developments.
