Colorbond® Steel Fencing
Supplied via DuraBond, Colorbond® steel fencing brings non-combustible fire performance to the 0–5 ft Zone 0 area; manufactured by BlueScope Steel Australia, with DuraBond as the official U.S. distributor.
What it is
Colorbond® is a pre-painted steel fencing system manufactured by BlueScope Steel Australia and supplied in the United States by DuraBond, the official U.S. distributor. The system uses a SMP factory coil coating (not powder coat) over galvanized steel, with individually replaceable panels.
Why steel suits the 0–5 ft zone
DuraBond states "Class A fire performance under ASTM E84" and describes the material as "non-combustible and does not ignite or contribute fuel to fire spread." BlueScope's fencing page states steel fencing "offers greater protection… against bushfire than other alternative materials because of its non-combustibility."
How we apply this to fencing; stated plainly:
No California Building Materials Listing category exists for fencing; the OSFM program lists WUI products in categories like decking, windows, siding, doors, vents, and ignition-resistant materials. Firewise applies Colorbond's listed/tested fire-resistance characteristics to fence and gate assemblies based on comparable exposure conditions to listed WUI applications, and we say so plainly rather than implying a fence-specific approval that doesn't exist.
Certification language, exact: manufactured to AS/NZS 1397/2728, standards the supplier describes as comparable to ASTM A792/A653. We do not state or imply that Colorbond is ASTM-listed.
BAL-FZ scope limit: BlueScope publishes BAL-FZ ratings for some of its products, but that rating names roofing, walling, and gutters specifically; not fencing. We do not use any BAL-FZ rating language from BlueScope on this page, because it would misrepresent the source.
Warranty
10-year material warranty, per DuraBond. BlueScope's own public materials do not state a U.S. fencing warranty duration; the 10-year figure is attributed to DuraBond specifically. Note that repainting may void the manufacturer warranty, per DuraBond.

How delivery works
A package means assessment, material specification, and coordination with a licensed local contractor who holds the contract and performs the work. "Includes materials, tax, labor, removal and disposal" describes what the package covers; not who performs the labor. Installation performance is always attributed to the licensed local contractor who holds the contract and performs the work.
