Product Overview

Welded Wire Reinforcement (WWR), also known as Welded Wire Fabric (WWF), is a prefabricated grid of high-strength steel wires welded together at their intersections. Our WWR is manufactured to meet the highest industry standards, providing consistent quality and reliable performance in various construction applications.

Mechanical Properties

• Tensile Strength: 70,000 to 80,000 psi (480 to 550 MPa)
• Yield Strength: 50,000 to 60,000 psi (345 to 414 MPa)
• Weld Point Strength: Approximately 35,000 psi (240 MPa)

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 the requirements of major building codes, including ACI guidelines, for specific structural applications.
