Wire mesh is a material that is made from various strands of interconnected metal, usually steel or aluminum. These strands can be welded together, extruded, or even connected by pins or other devices. The size and permeability of the wire mesh will often dictate its various uses; thinner mesh can be used as pasta or vegetable strainers, whereas larger, pinned mesh can be used as a conveyor belt in an industrial setting. Sometimes this type of mesh is used in gardening and landscaping applications as well.
One of the most commonly used types of mesh is welded wire mesh. This is often used in concrete construction, as the mesh can be laid down before the concrete is poured. The concrete can then be poured around the mesh, and once it sets, the concrete will have a higher tensile strength because the wire mesh contained within will help stabilize the often brittle concrete. This type of mesh is often used in place of steel rebar, which is a series of interconnected steel rods. Mesh tends to be easier to install and it comes at a lower cost than rebar for concrete projects.
