120 Truss-Mesh is a truss type continuous length joint reinforcement for single wythe walls. Hohmann & Barnard’s Lox All® Truss-Mesh and Lox All® Ladder-Mesh are continuous lengths of joint reinforcement that are embedded into the horizontal mortar joints of masonry walls Joint reinforcement has long proven to be necessary for superior performance of masonry wall construction, as it offers the following benefits: Reinforces a variety of masonry walls Greatly reduces cracking that can arise from thermal stresses Enhances resistance to water penetration, as cracks are controlled Increases lateral flexural strength Bonds exterior and interior masonry wythes together in composite walls Bonds masonry at intersecting walls and corners Increases elasticity Increases performance of masonry walls under various stresses Fabricated in conformance with ASCE/ACI 530 building code requirements for masonry structures, and ASTM A 951 (standard specification for masonry joint reinforcement) Effective Area of Horizontal Joint Reinforcement for Hohmann & Barnard Continuous Systems Chart (PDF) GAUGES: Reinforcing can be STANDARD WEIGHT (9 ga x 9 ga), EXTRA HEAVY (3/16" Side Rods x 9 ga Cross Rods) or SUPER HEAVY DUTY (all 3/16") AVAILABLE FINISHES: Mill Galvanized Hot Dip Galvanized Stainless Steel DIMENSIONS: Packed 500’ per bundle (50 pcs. - 10' long) Tri-Mesh, Twin-Mesh and Box-Mesh packed 250’ per bundle (25 pcs. - 10’ long) Corners and Tees packed 25 pcs per bundle
