DuraBond / 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, which identifies itself as the official U.S. distributor. The system uses a SMP factory coil coating (not powder coat) over galvanized steel, with individually replaceable panels. Review the current DuraBond source alongside the attributed details below.
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:
The OSFM Building Materials Listing program includes an ignition-resistant-material category and at least one steel fencing product. We have not found a listing for a Colorbond fence assembly, so this page does not present Colorbond as an OSFM-listed fence system.
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.
