Like rebar, welded wire reinforcement mesh is commonly used in construction for reinforcing concrete structures such as slabs, walls, and pavements. The mesh helps to distribute loads and provide tensile strength to the concrete, reducing cracking and increasing durability.

These meshes come in various sizes, wire gauges, and configurations. Continue reading to know more about their different sizes.

Welded Wire Reinforcement Types

Welded wire reinforcement comes in various types designed to meet specific construction needs. Here are some common types of reinforcement welded wire:

• Standard welded wire mesh: This is the most common type of welded wire reinforcement. It consists of parallel longitudinal wires welded to perpendicular cross wires at regular intervals. Standard welded wire mesh is available in various wire gauges, mesh sizes, and sheet dimensions.
• Structural welded wire reinforcement: Specifically designed to provide structural support in concrete applications. It typically features larger wire diameters and closer spacing between the longitudinal and transverse wires to enhance load-bearing capacity and durability.
• Flat mesh sheets: Flat mesh sheets are made with a flat profile, often used for applications where a smooth surface finish is desired. They can be used in applications such as slabs, walls, and architectural elements.
• Trench mesh: This type of welded wire reinforcement is used in the construction of footings and foundation slabs. It commonly features bent or protruding ends to facilitate proper positioning and anchoring within the concrete.
• Mesh rolls: Mesh rolls consist of welded wire reinforcement wound into rolls for easy transportation and handling. They are commonly used in applications where large quantities of reinforcement are required.
• Wire fabric grids: Used in applications such as bridge decks, airport runways, and industrial flooring. They provide high-strength reinforcement while minimizing concrete cover requirements.
• Galvanized welded wire reinforcement: Galvanized welded wire reinforcement is coated with a layer of zinc to enhance corrosion resistance, making it suitable for use in harsh environments or where exposure to moisture is a concern.

Welded Wire Sizing

Welded wire size comes in various sizes to meet the diverse needs of construction projects. The sizes refer to the dimensions of the mesh openings and the thickness of the wires used. These are some common sizes:

• Mesh openings: The size of the openings in the mesh can vary widely depending on the application. Common sizes include 4×4 inches (10×10 cm), 6×6 inches (15×15 cm), and 8×8 inches (20×20 cm). Smaller openings provide more support and are often used for heavy-duty applications, while larger openings may be suitable for lighter reinforcement needs.
• Wire diameter: The thickness of the wires used in the mesh also varies and is usually specified in terms of wire gauge. Common wire gauges for welded wire reinforcement mesh include 6 gauge (0.192 inches or 4.88 mm), 8 gauge (0.128 inches or 3.26 mm), and 10 gauge (0.102 inches or 2.59 mm). Thicker wires provide greater strength and durability.
• Sheet dimensions: The overall dimensions of the mesh sheets also vary. Standard sheet sizes typically range from 4 feet (1.22 meters) to 12 feet (3.66 meters) in width and 8 feet (2.44 meters) to 20 feet (6.10 meters) in length.
