Applications

• Slabs on Grade: Ideal for residential, commercial, and industrial floors to control shrinkage cracking and enhance load-bearing capacity.
• Walls: Provides structural reinforcement for both cast-in-place and precast concrete walls.
• Pavements: Used in concrete pavements, driveways, and sidewalks to improve strength and durability.
• Precast Products: Enhances the load-bearing capacity and durability of precast concrete products such as pipes, tanks, and beams.

Advantages

• Ease of Use: Simplifies installation, reducing labor time and costs compared to traditional rebar.
• Consistency: Factory production ensures uniform wire spacing and consistent quality.
• Strength: Offers excellent tensile strength and crack resistance, improving structural integrity.
• Reduced Labor: Can be installed more quickly than traditional rebar, reducing overall project costs.
• Efficient Material Use: Minimizes material waste due to precise manufacturing processes.

Installation Tips

• Placement: Typically placed in the middle or slightly above the middle of the concrete slab to optimize reinforcement.
• Overlaps: Proper overlapping of sections (8 to 12 times the wire diameter) is essential for continuous reinforcement.
• Support: Use chairs or other support devices to maintain the correct position during concrete pouring.

Compliance and Standards

• ASTM Standards: Manufactured according to ASTM A1064 for carbon steel wire, ensuring quality and consistency.
• Building Codes: Meets requirements of major building codes including ACI guidelines for specific structural applications.
