Welded wire mesh is a grid-like structure made of metal wires welded together at their intersections, providing strength, support, and security. It is created by welding wire strands at precise intervals, resulting in a durable and strong material used in various applications, such as concrete reinforcement, fencing, and filtration. Its properties can be customized by varying the wire type, coating, and spacing. 
Welded wire mesh is also sold in specific dimensions, such as 8 ft x 4 ft panels or 5 ft x 150 ft rolls.
