Welded Wire Reinforcement (WWR) is a steel reinforcement material consisting of wire strands welded together to form a grid-like structure. It is commonly used in concrete construction to reinforce slab, beam, and column elements. WWR can be produced in various sizes and configurations to suit the specific needs of the project. The most common size is 4-inch by 4-inch (100 mm by 100 mm), but other sizes are also available. The wires in the grid can be arranged in different ways to create different strengths and properties. For example, the wires can be arranged in a staggered pattern to create a stronger reinforcement, or they can be arranged in a straight pattern to create a lighter reinforcement. WWR is available in two main types: plain and deformed. Plain WWR has a smooth surface, while deformed WWR has a textured or ribbed surface. The type of WWR used will depend on the application and the specific requirements of the project.
