KAYU-Golden™ Bangkirai (Yellow Balau) Hardwood Fences & Gates
KAYU® Yellow Balau, marketed by KAYU International as KAYU-Golden™ Bangkirai, carries an independently verified Class A Flame Spread rating on the OSFM Building Materials Listing.
Naming: stated exactly
KAYU® Yellow Balau, marketed by KAYU International as KAYU-Golden™ Bangkirai, carries OSFM Building Materials Listing No. 8110-2069:0002 (Class A Flame Spread, Decking for W.U.I.). The listing itself says "Yellow Balau"; we never call this listing "Golden Bangkirai" on its own without that attribution.
Certification: quoted exactly from the OSFM listing
OSFM Building Materials Listing No. 8110-2069:0002; Listee KAYU INTERNATIONAL INC.
"KAYU® Yellow Balau solid wood decking boards, square edge. Boards are nominally 1" thick x 6" wide with edge-to-edge gap space of 3/16"."
Class A Flame Spread; Category 8110, Decking (W.U.I.)
Test Protocol SFM 12-7A-4A and ASTM E84, Date Issued 05/31/2026, Listing Expires 06/30/2027
Profile scope limit: The listing covers a specific board profile; nominal 1"×6", square edge, 3/16" gap. We do not imply every Bangkirai profile is covered by it.
Approval condition (from the listing): Decking use requires the attached exterior wall covering to comply with CBC §707A.
OSFM disclaimer: A Building Materials Listing "is not an endorsement or recommendation." We never characterize this listing as OSFM endorsing the product.
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. This KAYU® listing applies to the listed material and use described by OSFM; it does not by itself approve every fence or gate assembly.
Class A ≠ non-combustible: We do not use "Class A" and "non-combustible" interchangeably anywhere on this page. Class A refers to flame-spread performance in standard tests; non-combustible is a material property. They are different classifications.
Verification dated July 26, 2026. The listing expires June 30, 2027; flag for re-verification before then.
