What is Concrete wire mesh
Concrete wire mesh, also known as welded wire mesh or reinforcement mesh, is a type of reinforcement used in concrete slab. It consists of a series of interconnected steel wires welded together to form a grid pattern. These grids are typically square or rectangular in shape and come in various sizes and gauges depending on the specific application.
Concrete wire mesh serves as a reinforcement to strengthen and support concrete structures. It helps distribute loads evenly, control cracking, and improve the overall durability and performance of concrete. The mesh is placed within the concrete at the time of pouring, providing additional tensile strength to complement the compressive strength of the concrete itself.
Concrete wire mesh is available in different configurations to suit different construction needs, including varying wire diameters, mesh sizes, and spacing between the wires. The specific type and size of wire mesh required for a project depend on factors such as the intended use of the concrete, the design requirements, and the structural considerations.
The concrete wire mesh can be in panels and sheets,with open edge or closed edge
Wire mesh for concrete also can be in rolls
When to use wire mesh in concrete
Wire mesh should be used in concrete under several circumstances:
Slabs: In concrete slabs, such as sidewalks, driveways, or floors, wire mesh is often used to reinforce the concrete and control cracking.
Thin Concrete Sections: When pouring thin sections of concrete, such as overlays or toppings, wire mesh can help prevent cracking and improve overall durability.
Heavy Traffic Areas: In areas where heavy loads or traffic will be present, such as industrial floors or vehicle driveways, wire mesh helps distribute the load and prevent cracking.
Control Joints: Wire mesh can be used in conjunction with control joints to help control cracking in concrete. It provides additional reinforcement at these vulnerable points.
High Temperature Variations: In regions where temperature fluctuations are significant, wire mesh can help minimize the effects of expansion and contraction, reducing the risk of cracking.
Structural Repairs: When repairing or reinforcing existing concrete structures, wire mesh can be added to improve their strength and longevity.
Underground Applications: In concrete placed underground, such as foundation footings or retaining walls, wire mesh can provide added stability and resistance to soil pressures.
Wire mesh is typically used in concrete applications where reinforcement is needed to control cracking, improve durability, and enhance structural integrity, especially in situations involving thin sections, heavy loads, or temperature variations.
