RE: Old Structural Mesh BF912

No any good leads yet.  My guess is same as yours (W9 wire @ 12”).  Thanks! - Martin

That's a tough one to figure out.  Any good leads yet?  I'll check our office library, but it sounds like a proprietary call-out.  My guess is the 9 means a No. 9 wire.  Maybe spaced at 12"o.c.  Good luck with this one.

We are working on a project that involves an existing reinforced concrete building with the drawings dated 1937.  The reinforcing specified for 3” slab over joists is BF912 Mesh.  Does anyone know BF912 Mesh?
