Description
Welded wire reinforcement (WWR) is prefabricated reinforcement consisting of high-strength cold-worked steel wires that are resistance-welded together in square or rectangular grids by continuous automatic welders. This report provides WWR product information, material specifications, and design/detailing recommendations, with an overview of manufacturing, shipping, and construction use in various applications of concrete construction.
Keywords: cast-in-place; cold-working; constructability; deformed reinforcement; mesh; precast; post-tensioned; prestressed; reinforcement; welded wire.
