MATERIALS:

• Plates and bars: ASTM A36
• Sheets – cold rolled: ASTM A366
• Sheets – hot rolled: ASTM A569

FINISHES:

• Mill Galvanized – ASTM A525 Class G60 (0.6 oz. zinc coating/FT.²) (ASCE/ACI 530.1 requires this coating for items completely embedded in mortar or grout)
• Hot Dip Galvanized – ASTM A153 Class B2 (1.5 oz. zinc coating/FT.²) (ASCE/ACI 530.1 requires this coating for items exposed to weather or not completely embedded)
• Stainless Steel ASTM A167, ASTM A240, Type 304, 2B Finish. H & B recommends Type 304 or Type 316 Stainless Steel for maximum corrosion protection

Wall Reinforcement
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 or cavity walls
• Bonds masonry at intersecting walls and corners
• Increases elasticity
• Cavity drip inhibits moisture penetration due to thermal condensation or water from exterior surfaces
• Increases performance of masonry walls under various stresses
• Fabricated in conformance with ASCE/ACI 530 building code requirements for masonry structures

Features:

1. Butt welding of cross rods to longitudinal rods (not more than 16" O.C.). This construction enhances bonding capabilities, eliminates projection of cross rods beyond the specified width or reinforcement, and prevents excessive build up of wire in limited mortar joints
2. Continuous deformation along each longitudinal rod for superior bonding performance
3. Choice of combination of wire gauges:
   
   • Standard weight – 9 ga. Side Rods x 9 ga. Cross Rods.
   • Extra Heavy – 3/16" Side Rods x 9 ga. Cross Rods.
   • Super Heavy Duty – 3/16" Side Rods x 3/16" Cross Rods
4. Material Conformance: See in profile

WIRE:

Prefabricated construction from cold-drawn steel wire, which conforms to ASM A82 (for tensile strength) and Federal Specification QQ-W-461f (for hard tempered wire).

FINISHES:

1. Brite basic – no coating
2. Mill Galvanized:
1. ASTM A641 – (0.1 ounce zinc coating/FT.²)
2. ASTM A641 Class 1 (0.4 ounce zinc coating/FT.²) Conforms to ASCE/ACI 530.1 required coating – interior walls
3. ASTM A641 Class 3 (0.8 ounce zinc coating/FT.²) Conforms to ASCE/ACI 530.1 required coating – exterior walls (if completely embedded)
3. Hot Dip Galvanized (after fabrication): ASTM A153 Class B2 (1.5 ounce zinc coating/FT.²)
   Conforms to ASCE/ACI 530.1 required coating – interior walls subject to moist environment – exterior walls (if not completely embedded)
4. Stainless Steel Type 304 ASTM A580 – H & B recommends Type 304 or Type 316 Stainless Steel for maximum corrosion protection.
