Wire Size: Imperial wire sizes are designated by their sectional area in hundreths of a square inch. Metric wire sizes prefix <M> are designated by their sectional area in mm2.

The most popular wire sizes for the design of WWR are: D3, D4, D4.5, D5, D7, D8, D9, D10, D11, D12, D14, D15.5, D16, D18, D20 and D31 Design in WWR with a maximum of 4 different diameters, as suggested in the table of equivalences below:

• Wire sizes up to D31 or W31 (0.310 in2, 5/8” diameter) • Mat sizes (8 ft –12* ft widths, up to 40 ft lengths) • Contractor appeal: jobsite labor and time savings

Put simply, WWR is a mild steel reinforcement that is interchangeable with reinforcing bars (rebar) in structural reinforced concrete design equations and is commonly specified in sizes up to and including 5/8” diameter deformed or plain structural wires (W31/D31). View/Download PDF

Welded reinforcement concrete mesh is one heavy type welded wire mesh products, widely used in concrete, construction and buildings. Cracks in concrete reinforcing products or soft ground is used for the purpose of reinforcing the foundation.

2013年11月1日 · Welded Wire Reinforcement (WWR) is seeing an increased use as shear reinforcement in bridge girders, such as AASHTO Type II, III, and IV-4, Bulb-Tee Girders and U-Girder Sections, due to its available increased strength and the reduction in time or labor cost to install the material in the precast beds.

worked wire and welded wire reinforcement (WWR) to assist in the design and detailing of WWR systems for concrete structures. Tables are included to compare steel areas for reinforcement with a minimum yield strength of 60,000 psi and three higher minimum yield strengths, i.e., 70,000, 75,000 and 80,000 psi, for WWR.

2019年7月15日 · Past research studies have been conducted on the ductility of concrete members reinforced with welded wire reinforcement (WWR) and determined a new phenomenon called strain localization reduces member ductility due …

2013年3月11日 · The wire reinforcement industry has adopted the term welded wire reinforcement (WWR) as being more representative of the applications of the products being manufactured. Therefore, the term welded wire fabric has been replaced with the term welded wire reinforcement in this specification and in related specifications.

Welded Wire Reinforcement (WWR) is a prefabricated structural component comprised of series of high-strength wires arranged in grids, providing enhanced bond strength and stress distribution in concrete applications. The design promotes mechanical anchorage and improves construction efficiency through ease of handling and reduced installation time.
