Publications and Documents

A pictorial and descriptive publication on the fabrication of either in-plant or on-site bending of welded wire for column cages, beam baskets, and shear reinforcement for both cast in place and precast/prestressed structural components.

This manual provides current product information, material specifications, and properties, and lists current ACI 318 Code provisions relating to WWR. Tables and design aids are included on splicing and areas of cross sections for various wire spacings. Two new sections cover testing of wire and welded wire reinforcement, as well as handling and placing guidelines.

The Welded Wire Reinforcement Design and Detailing Guide (“The Guide”) provides contractors and designers a comprehensive benchmark for the incorporation of WWR into contract documents used on site. It explains by example why (a) the structural Engineer-of-Record (EOR) needs no proprietary-like knowledge in order to implement WWR into their contract drawings, and (b) the protocol-in-use for reinforced concrete design and detailing need not be overhauled in order to accommodate WWR usage. The Guide is best used as a complement document to design and detailing standards publications, creating value by offering detailed insights specific to welded wire reinforcement.

This Tech Fact is an educational tool for welded wire reinforced tilt-up wall construction.

This Tech Fact is intended to provide sound recommendations for use in estimating the reinforcing steel in a concrete pipe. The information in tables in the book were compiled using the published reinforcing designs of the American Society for testing and materials "Standard Specification for Reinforced Concrete Culvert, Storm Drain, and Sewer Pipe", Designation C 76.

A comprehensive publication that answers many questions on specifications and nomenclature on wire sizes and styles for ordering information. It also has guidelines on placing and supporting WWR. There are numerous examples, data tables, and photos.

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.

Third Printing 5 pages Converting U.S. Equivalent Customary (in-pound) styles to Metric styles. A discussion and examples of soft conversion technique.

The questions of "why" and "where" supports are necessary are covered in this publication. Types of supports for WWR and the influence of the sub-base conditions on their selection are addressed. Suggested spacings of supports are furnished to show the different spacings when wide spaced WWR (step-through styles) is specified vs. the smaller spaced styles.

This Tech Fact describes 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.

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 subgrade 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").

This tech fact will give guidance to design professionals, contractors and building/bridge owners on the physical and mechanical properties of older wire and wire mesh and welded wire reinforcement. There are references to ASTM standards that give structural properties used in the 1900s to the 1960s and a table of wire gages with diameters, areas, and weights listed. An example table is included on the nomenclature of triangular wire used in the early 1900s. In addition, a story on the history of wire, wire mesh and WWR for concrete reinforcement and a statement on "This Modern Era" - or where the WRI industry is today.

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.

Contained in this Tech Fact are the principles of reinforcement and why it's needed in concrete pipe design. D-Load requirements and manufacturing specifications are explained. Examples show metric styles of WWR compared to in-lb styles. Other tables show Canadian Standards, conversion factors, common pipe WWR wire spacings and common wire and dimensional properties for metric sizes as well as in-lb sizes.

This Tech Fact contains key ACI 318 code provisions concerning wire and welded wire reinforcement for reinforced concrete. The reference can be used as a guide for design expressions, approved ASTM material references, and commentary to assist in design and writing specifications. The Tech Fact may be inserted in the WRI Structural Detailing Manual -Section 1- and will be updated as future codes are published.

The WRI Manual of Standard Practice, 2016 edition

A manual on the design, construction, and maintenance of jointed, reinforced pavement.

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.
