Innovation In Masonry Construction

Ladder 4 Wire


4 Wire has 4 Side Rods to reinforce block and brick composite walls. Ladder Series 200 design is a prefabricated reinforcement for embedment in the horizontal mortar joints of masonry. It is manufactured in 10′ 8″ lengths from wire conforming to ASTM A1064/A1064M, ASTM A82/ A82M

4 Wire consists of 4 parallel and deformed longitudinal wires welded to a perpendicular cross wire spaced 16" O.C. Out-to-out spacing is approximately two inches less than the nominal thickness of the wall.

  • 16" O.C. ladder design positions cross rods on web of block to allow core clearance.
  • Simplifies rebar installation; centering utilizes strength of grout.
  • Allows unrestricted flow of grout or loose fill insulation into CMU cells.
  • Minimizes re-setting of joint reinforcement around rebar.
  • Improves resistance to shrinkage cracking.
  • Provides stronger bond with cross rods in web of block.
  • Less time devoted to rebar installation, grout pouring.
  • Meets ASCE/ACI 530 building code requirements for masonry structures and ASTM A 951 (standard specification for masonry joint reinforcing).
