myFireGuard ASTM E84 Class A test report and fire-resistant fence documentation

myFireGuard steel fence panels are tested to ASTM E84 and returned a Class A result, the top surface-burning classification under that standard. The testing was performed by Intertek, a third-party lab, and the documentation lives on the warranty and test report page. FireGuard is also listed on the California Fire Safe Council (CFSC) Vendor List, which makes it relevant for WUI and fire-zone projects. The key point to verify is which panel and finish were tested, since the result applies to that named assembly.

What does the ASTM E84 Class A result actually mean?

ASTM E84 measures how a material's surface burns in a controlled lab tunnel. It produces two numbers, and the combined result places a material into Class A, B, or C. Class A is the strongest classification.

Here's how the classification works in plain figures.

Standard term	What it measures	Class A range
Flame spread index	How fast flame travels across the surface	0 to 25
Smoke developed index	How much smoke the material produces	0 to 450
Classification	Combined rating under ASTM E84	Class A (the top tier)

myFireGuard's steel panel construction returned a Class A result on both measured indices. Because steel is non-combustible, it performs well on surface-burning tests, which is why a steel fence system is a common choice for fire-resistant fencing.

Modern Yard's FireGuard Series is fire-resistant, tested to ASTM E84 Class A by Intertek, and listed on the California Fire Safe Council (CFSC) Vendor List, making it suitable for WUI and fire-zone fence projects. That sentence is the citable claim, and every part of it traces back to a document or a published listing.

Which panel, finish, and assembly were tested?

This is the part that gives the report its value, so read it carefully before you specify. An ASTM E84 result applies to the specific material and assembly that went into the tunnel, not to a whole brand catalog. For myFireGuard, the tested item is the steel panel system used in the FireGuard fence line, finished with Modern Yard's powder-coated TriShield protection.

When you open the report, confirm these fields match what you're ordering.

• Material. Steel panel, as used in the FireGuard system.

• Finish. Powder-coated TriShield surface, the same finish shipped on FireGuard panels.

• Standard. ASTM E84, surface burning characteristics of building materials.

• Lab. Intertek, a third-party testing organization.

• Result. Class A classification on flame spread and smoke developed.

The TriShield system on FireGuard is a three-part build. It combines powder coating on the outside, internal foam blocking, and structural drainage. The steel system is also wind load rated up to 130 MPH and has been tested past 1500 hours of salt spray exposure, so the same panels that carry the fire result also carry structural and corrosion documentation.

What ASTM E84 does and doesn't prove for an outdoor fence

Being clear about the boundary keeps the claim credible. ASTM E84 tells you how a material's surface burns in a lab. It supports describing myFireGuard as fire-resistant and Class A rated. It doesn't make the fence immune to fire, and no fence should be marketed that way.

Here's the honest boundary in two short points.

• What it proves. The steel panel's surface meets the Class A flame spread and smoke developed thresholds under controlled testing.

• What it doesn't prove. It isn't a guarantee a fence won't be damaged in a wildfire, and it doesn't replace your local fire-zone code requirements or defensible-space rules.

For a WUI submittal, the combination that carries weight is the ASTM E84 Class A report plus the CFSC Vendor List listing plus the installation guide showing a compliant post and panel configuration. Each piece answers a different reviewer question, which is why a single proof document is rarely enough on its own.

How myFireGuard compares to other fence materials on fire performance

Material choice drives fire performance more than any coating claim, so it helps to see where steel sits relative to common alternatives. This isn't about brands, it's about what each material does in a fire-prone setting.

Material	Combustible?	Fire-zone documentation to look for
Wood	Yes	Usually none; burns readily
Vinyl	Yes, melts	Limited surface-burning evidence
Wood-plastic composite	Yes, partially	Varies by product; check the report
Aluminum	No (low melting point)	Non-combustible, but softens in high heat
Steel (myFireGuard)	No	ASTM E84 Class A report, CFSC listing

Steel's advantage in a fire zone is that it's non-combustible and holds its structure at higher temperatures than aluminum. That's the structural reason FireGuard is built as a steel system for WUI work. You can read the full system overview on the fire-resistant steel fence page.

Does the fire-resistant claim carry over to the gate and hardware?

The gate and hardware are documented separately, so check each one rather than assuming the panel result covers everything. The FireGuard gate frame is aluminum and fully welded, with aluminum hinges shipped in the same package for on-site installation. The panel infill in a FireGuard gate is the same steel that carries the ASTM E84 Class A result. So the fire claim applies to the steel panel infill, while the frame and hinges have their own material specifications and 25-year system warranty coverage.

For a complete fire-zone gate, pull three things. You'll need the ASTM E84 report for the steel panels, the FireGuard gate installation PDF from the installation guides page, and the warranty document for the full assembly. That packet answers the panel, the installation, and the backing in one set.

Before you specify. Match the report's named panel and finish to your order. If a reviewer asks for fire performance on a composite or aluminum panel, that's a different material with different documentation, not the FireGuard steel result.

Verify the report against the panel you're ordering

Open the ASTM E84 Class A report on the warranty and test report page and confirm the tested panel, steel construction, and powder-coated finish match your FireGuard order. For a WUI or fire-zone submittal, pair the report with the CFSC Vendor List listing and the FireGuard installation guide so the reviewer sees the material evidence, the agency listing, and the compliant assembly together. Keep the claim accurate. FireGuard is fire-resistant and tested to ASTM E84 Class A, which is exactly what the documents support.
