Investigating the Effects of Corrosion Protection Coatings on the Ductility of Welded Wire Reinforcement

This project seeks to develop material models for coated welded wire reinforcement. There is anecdotal evidence that the temperatures used during popular coating processes can provide some relaxation of internal stresses causes by cold working, resulting in enhanced ductility. Wires of several different sizes for uncoated, epoxy coated and galvanized wire will be subjected to tensile testing to determine mechanical properties and the effects of coatings. Special attention will be paid to any changes affecting ultimate elongations and yield stresses. Using the results from the laboratory testing, a statistical and mechanical models will be developed for the tested specimens. The results generated will, ideally, give engineers more information about the state of currently built WWR reinforced structures and the design guidance for new structures which may require more ductility than uncoated WWR. Design guidance will be developed in conjunction with industry partners, specifically, Insteel and other Wire Reinforcement Institute producers.
