An effort is underway to modernize the way CMU horizontal wire reinforcing is manufactured, packaged, shipped, and installed. These changes û if implemented û will enhance bricklayer productivity by optimizing lapping and narrowing the profile (height) where the pintles are welded to the wire.
At the time of this writing, the three major wire manufacturers were slow to recognize the changing landscape of CMU construction. The days of truss wire, 15-inch o.c. ladder, and lap-welded adjustable wire are fading. They have not yet dedicated production capacity producing these new ladder systems, but claim they have stepped up research and development and plan to meet demand when it reaches a practical level.
The three manufacturers in the field are Dur-O-Wal Inc., Hohmann & Barnard Inc., and Masonry Reinforcing Corporation of America Inc.
