Which material is available in sheets and rolls and is used to reinforce concrete?

Welded wire reinforcement is a crucial material used in construction to enhance the strength and stability of concrete structures. It is made from steel wires that are welded together in a grid pattern, creating a mesh that is available in both sheets and rolls. This versatility allows it to be easily handled and installed in various concrete applications, such as slabs, walls, and pavements.

The purpose of this reinforcement is to provide tensile strength to the concrete, which is essential because while concrete excels at bearing weight, it is relatively weak in tension. By incorporating welded wire reinforcement, the overall structural integrity is improved, aiding in the prevention of cracking and enhancing durability under load.

Other materials like wire mesh and fiberglass may be used for similar purposes but typically serve different functions or have specific applications based on their properties. Wire mesh is often a more general term that doesn’t necessarily indicate the welded aspect, while fiberglass is used primarily for its lightweight and corrosion-resistant properties rather than for concrete reinforcement. Plastic sheeting, on the other hand, serves a different function such as moisture control and protection rather than reinforcing concrete.
