Re: Bar versus Wire

[Subject Prev][Subject Next][Thread Prev][Thread Next]

WWF, welded wire fabric mesh utilizes these  very wires. I'll research on why would any one specify on use of wires instead of a rebras. But you have a point there definitely, about cost economics which might off set the savings other wise.

We have been using wires or WWF only at places where we have too many cuttings (due to utility trenches) especially on Slab-on-Grade, where rebar detailing & placing becomes sort of very difficult & time consuming. Here again, economics of its governs, in favor of its use and not against it.

So, its use is merited by its necessity, as I undestand, depending on case to case basis.
