Class A Fire Rated. Built Around Aluminum.
Build the panels nearest your house with Cap Coat Aluminum Rails. They slide into the same slot posts as your Valla or Riviera composite boards, so the fire-rated stretch and the rest of the run read as one fence.
Each rail is a wood-grain cap coat over a hollow, chambered aluminum core that doesn’t burn. Independent SGS testing to ASTM E84 puts it in the highest surface-burning category, Class A.

Put Class A Where It Matters Most
Wind-driven embers start most wildfire house fires, and a combustible fence running up to the wall can carry flames straight to the structure. Build the stretch of fence closest to your home with Cap Coat Aluminum Rails, then continue the run in color-matched Valla or Riviera cap composite.

- Slide in the railsDrop each rail down the post channels for the panels nearest the house.
- Finish the runContinue in Valla or Riviera boards in the matching color.
Tested, not claimed
Third-party SGS test report to ASTM E84-24: Flame Spread Index 20, Class A surface-burning category.
A core that won’t burn
The chambered aluminum interior is non-combustible and holds its shape under heat.
One continuous look
Rails come in the same colors as our cap composite boards, so the fire-rated section blends into the rest of the fence.
Zone 0, the ember-resistant zone, is the first 5 feet around your home. The emerging state standard calls for that zone to be built from non-combustible or ember-resistant materials, and flags combustible fences that run up to the house. Our non-combustible, Class A Cap Coat Aluminum Rails are a strong fit for that stretch of your fence.
Add a Top Accent to Valla & Riviera
The same rails that build your fire-smart section also make a finished top rail. Slide one into the Valla or Riviera slot posts above your composite boards for a clean, architectural line.
How Homeowners Use Cap Coat Aluminum Rails
Fire-smart privacy section
Fill Valla or Riviera slot posts with rails for the 5–8 ft of fence closest to your home.
Accent top rail
Run a rail along the top of a Valla or Riviera panel for a finished, architectural look.
Picket fence framing
Mount rails to posts with the 2 included color-matched T-bracket connectors, then fasten composite pickets to them.
The Strength of Aluminum. The Look of Wood.
Each rail is extruded aluminum with a thin, protective cap coat fused directly to the core. The cap gives you a natural wood-grain finish and shields the aluminum from moisture, salt-air corrosion and fading.
- Never needs painting, staining or sealing
- Resists moisture, mold and salt-air corrosion
- Anti-fungal and anti-bacterial additives
- Termite and pest resistant
- Color-fade resistant cap coat
- Stronger than vinyl, with none of wood’s upkeep

Common Questions
Are Cap Coat Aluminum Rails fire rated?
Yes, both the 6 ft and 8 ft rails. They are rated Class A for surface-burning characteristics under ASTM E84-24, with a Flame Spread Index of 20, per third-party SGS test report SDFTS26002267R02_EN. Class A is the highest rating in that standard.
Will they fit my Valla or Riviera fence posts?
Yes. The rails slide into the channels of Valla and Riviera slot posts, so you can build a fire-smart section or a top accent using the same posts as the rest of your fence.
Can I use them in California’s Zone 0?
The non-combustible aluminum core and Class A rating make them a strong fit for the first 5 feet around your home. Zone 0 rules are still being finalized by CAL FIRE and the Board of Forestry, and some local jurisdictions have adopted their own, so confirm the requirements for your address with your local fire authority.
Will the color match my composite fence?
Rails come in Barandilla de Caoba, Punta de hierro, Abeto de río, Barandilla de Cedro, Barandilla de teca, Barandilla de cedro rojo, the same palette as our cap composite boards, so the aluminum section reads as part of one continuous fence.
What comes with each rail?
Each rail ships with 2 color-matched T-bracket connectors for mounting to posts in picket and rail-style fences. No connectors are needed when sliding rails into Valla or Riviera slot posts.
Do they need painting or staining?
Never. The cap coat is fused to the aluminum core and resists fading, moisture, mold and pests. Rinse with water to clean. Every rail is backed by a 30-year warranty.
Class A rating per SGS test report SDFTS26002267R02_EN (ASTM E84-24, Flame Spread Index 20) for surface-burning characteristics. California’s Zone 0 requirements are being finalized by CAL FIRE and the Board of Forestry and are phasing in over time; some local jurisdictions (e.g., San Diego) have adopted rules ahead of the state. This product is not a guarantee of code compliance — confirm current ratings, warranty terms, and the defensible-space requirements for your address with CAL FIRE or your local fire authority before use.
