Greenfield's Steel Privacy Wall has a historical ignition-resistant fencing listing whose present availability needs confirmation.
OSFM's handbook identifies the wall in listing 8170-2409:0001. Its carbon-steel tubing conforms to ASTM A653 Structural Steel Grade 50. The construction combines three tubing sizes: 14-gauge with a 4-by-4-inch section, 16-gauge with a 2-by-4-inch section, and 18-gauge with a 1-by-6-inch section. Those gauge-and-section pairs describe the listed wall; specifying steel alone loses the construction being identified.
The handbook places this fencing material in the ignition-resistant category and reports ASTM E84 with an extended 20-minute test. That is the stated fire-test basis for this privacy wall. OSFM leaves the detailed construction to Greenfield's product data sheets and installation instructions.
The retained BML search did not contain this listing, so its listing status is lapsed. Its absence does not establish whether it expired, was withdrawn or received a new identifier. For a proposed fence, obtain a matching current GOVmotus record and the manufacturer's complete wall detail before relying on the historical listing.
