2006, 10 chapters have been updated and case studies and tech facts have been included
Members only - Contact a WRI Producer Member
This manual may be used for detailing guidance on welded wire reinforcement in one-way and two-way slabs, precast/prestressed concrete, column & beam detailing, cast-in-place walls, and slabs-on-ground. Sections also cover ACI 318 provisions and shortcuts to compare areas of high strength WWR with areas of mild reinforcing.
A Sample Specification for Welded Wire Reinforcement (WWR)
2006, 6 pages
We have had many requests for an example of a Sample Specification that design and construction professionals may review when preparing their own construction documents. This is a sample specification prepared by an engineer with a WRI member producer. (Please review the WRI Disclaimer attached at the end of the document.)
WRI Tech Facts

This Tech Fact is an educational tool for welded wire reinforced tilt-up wall construction.
TF 205-R-03: Welded Wire Fabric in Concrete Pan Joist Slab Construction
1993, First Printing, 2 pages An informative publication referencing the advantages of welded wire reinforcement (WWR) in both one-way and two-way pan joist construction. Addresses minimum steel requirements, spacing, design considerations, ACI Building Code specifications, and the use of high strength structural WWR.
TF 208-R-08: (D) Structural High Strength Welded Wire Reinforcement - Current Product Knowledge
2008, 3rd Printing, 6 pages
This Tech Fact describes current manufacturing abilities, applicable specifications and nomenclature, handling and unloading, placing to obtain proper positioning, coated WWR, and metrication. Tables are included to make it easier for converting units and knowing what common styles are produced and determining areas of steel for various wire spacings.
TF 209-R-08: Design Aids For Structural Welded Wire Reinforcement (includes WWR/Rebar Comparison Tables)
2008, 2nd Printing, 14 pages
This issue contains lists of ASTM & AASHTO Standards that apply to wire and WWR. Also ASTM physical properties for minimum yield and tensile strengths and minimum weld shear strength criteria. There are examples using the included 4 sets of tables. The tables compare various spacings of rebar at 60 ksi yield strength with various spacings of WWR at 60, 70, 75, and 80 ksi yield strengths.
TF 209-0 Metric: Design Aids For Structural Welded Wire Reinforcement (includes WWR/Rebar Comparison Tables)
2008, 2nd Printing, 14 pages
This issue is a metric-centered version of TF 209-R-08.
TF 700-R-07 (WRI/CRSI 81): Design of Slab-on-Ground Foundations
Original 1981, 36 pages
A design and construction aid specified by many model, local, and state code bodies. It's used by many testing and inspection agencies. It contains material to detail slab-on-ground and supporting concrete structures on soft or expansive soils, prevalent in many parts of the country. Design of Slab on Ground Foundations: An Update.
TF 704-R-03: High Strength Welded Wire Reinforcement Compared with Rebar
1995, 2 pages
This Tech Fact shows an actual distribution facility project that saved considerable costs on the placing of WWR compared with rebar. The high strength WWR saved material costs alone to convince the owner and contractor to use WWR. The contractor's statements give credence to the importance and viability of the use of WWR over rebar in concrete paving, parking lots, and slabs-on-ground.
TF 705-R-03: Innovative Ways to Reinforce Slabs-on-Ground
1996, 8 pages, by Robert B. Anderson, P.E.
There are five design procedures with examples developed by Mr. Anderson, a leading consultant on the subject of reinforced concrete slabs-on-ground. The publication has derivations of equations and design examples that show how as steel area increases more crack width control is gained. The sub grade drag theory is explained here in more detail, emphasizing the procedure for residential and light commercial projects. The other four procedures should be used for various structural applications where wheel loads and rack loads play a greater role in the design of the slab. There is a table of cross-sectional areas and weights for different spacings of wire (from 3" to 16").
WRI Case Study
CS 194-R-03: Case Study - Multiple Uses, One Project - Jacob's Field, Cleveland Indians Ball Park, Cleveland, Ohio
1994, 4 pages
Examines use of 490 tons of high strength WWR for paving, slabs-on-grade, supported corridor slabs, precast units, and beam shear cages. Value engineering played a big role in saving money and helped construction stay ahead of schedule. Cost savings of $125,000 were realized by reduced forming turnover time and placing time. By using high strength WWR over conventional strength reinforcing, 15% of the material costs were saved.
CS 198-R-03: Case Study - Concrete Bridges with Structural High Strength Welded Wire Reinforcement
1998, 6 pages
Discusses the research by the University of Nebraska on precast/prestressed "I" girders and some actual designs and the construction utilizing that research. Also, some recent innovations in the use of structural welded wire reinforcement in bridge deck replacements. Some precast bridge rail members, median barriers, and sound walls are shown in the case studies.
CS 298-R-03: Case Study - Tunnel Construction - Washington DC's Metro Tunnel: An Advancement in Concrete Reinforcement
1998, 2 pages
Washington, DC's Metro subway is among the world's highly regarded public transit systems. The 1.1 mile extension of the green line utilizes high strength welded wire reinforcement equivalent to the area of steel of #6 @ 6" as primary reinforcement and #4 @ 16" temperature/shrinkage reinforcement. The welded wire sheets were shipped radius bent.
