Concrete Wire Mesh

Concrete wire mesh, also called welded wire reinforcement (WWR), is a grid of plain or deformed steel wires electrically welded at their intersections and placed within concrete slabs, sidewalks, driveways, walls, and similar elements. 

Concrete wire mesh is primarily made from steel wire arranged in a square or rectangular grid and electrically welded at each intersection. We select the wire material, surface profile, finish, and fabrication method according to the concrete element, exposure conditions, structural design, and applicable specifications. 

Carbon-steel welded wire reinforcement commonly follows ASTM A1064/A1064M.

• Carbon-steel wire: We commonly use carbon steel made from hot-rolled rod that is cold-drawn or cold-rolled into reinforcing wire. This process produces strong, consistent wire suitable for concrete reinforcement. The steel can be plain or deformed and is welded into stable mesh panels or rolls.
• Plain or deformed surface: We can use plain wire with a smooth surface or deformed wire featuring ridges, indentations, or protrusions. Deformed wire improves mechanical bond with hardened concrete, while plain wire remains suitable where the project specifications and intended application allow its use.
• Welded intersections: We create the mesh by resistance-welding the crossing longitudinal and transverse wires with controlled automated equipment. These welded joints form a rigid grid that maintains the specified spacing during handling and concrete placement, rather than relying on manually tied individual bars.
• Protective coatings: We supply bare steel for conventional applications and can add corrosion-resistant finishes when exposure demands it. Galvanized mesh uses a zinc coating, while epoxy-coated mesh uses a protective polymer layer. These options help protect the reinforcing steel in moisture- or chloride-prone environments.

Concrete wire mesh is used to reinforce concrete where added tensile capacity, crack control, and uniform steel distribution are needed. 

We place the mesh at the designed depth within the concrete—not on the ground—to help it perform as intended. Its prefabricated grid speeds installation and supports consistent reinforcement across large pours.

• Slabs and floors: We use concrete wire mesh in residential slabs, warehouse floors, patios, and garage floors to distribute reinforcement across the surface. It helps manage temperature- and shrinkage-related cracking, supports durable service performance, and provides a more consistent reinforcement layout throughout the concrete placement.
• Driveways and pavements: We install mesh in driveways, sidewalks, road pavements, and runway slabs where repetitive traffic and environmental movement can cause cracking. It does not eliminate cracks, but helps limit crack width and hold adjacent concrete sections together after cracking occurs.
• Walls and foundations: We use heavier welded wire reinforcement in concrete walls, foundation walls, footings, retaining walls, and structural linings when specified by the engineer. The mesh distributes reinforcement in two directions, helping these elements resist applicable loads and maintain their intended shape.
• Precast concrete products: We use wire mesh to reinforce precast wall panels, concrete pipes, boxes, barriers, and similar factory-made elements. The consistent, welded grid simplifies repeatable fabrication, improves handling strength, and supports dependable reinforcement placement before the concrete is cast and cured.

Attaching wire mesh to a concrete wall requires the right fasteners and proper spacing. We recommend choosing the attachment method according to the mesh type, wall condition, and intended use. With accurate drilling and secure fixing, we can create a stable installation that stays firmly against the concrete surface.

• Choose the right fasteners: We select concrete screws, masonry anchors, or expansion anchors based on the mesh weight and wall condition. These fasteners provide reliable holding strength and help keep the wire mesh securely attached.

• Mark the installation points: We measure and mark evenly spaced fixing points along the mesh edges and center. Proper spacing distributes the load and prevents the mesh from becoming loose, warped, or uneven.

• Drill into the concrete: We use a masonry drill bit to create holes at the marked points. The holes should match the recommended diameter and depth of the selected concrete anchors for secure installation.

• Position the wire mesh: We place the wire mesh against the concrete wall and align it with the drilled holes. We keep the mesh flat and properly positioned before inserting the fasteners.

• Secure the mesh: We insert concrete screws or anchors through the mesh openings and tighten them firmly. We avoid excessive tightening, which could deform the wire or damage the protective coating.

• Check the installation: We inspect the entire mesh after fastening to ensure there are no loose sections or sharp protruding edges. We also confirm that the mesh remains properly aligned and firmly attached.

Supporting wire mesh correctly in concrete helps keep it at the proper height during pouring and curing. Proper placement improves reinforcement performance, helps control cracking, and supports the slab’s structural integrity. 

The right support method depends on slab thickness, project requirements, mesh size, and whether the concrete is poured on the ground or within a structural framework.

• Use wire mesh chairs: Place chairs beneath the mesh to maintain the required elevation and concrete cover.

• Install concrete blocks: Use suitable precast concrete spacers to support the mesh above the subgrade.

• Secure the mesh: Tie overlapping sheets together with binding wire to prevent movement during concrete placement.

• Maintain proper spacing: Position supports at suitable intervals to reduce sagging and keep the reinforcement evenly distributed.

• Check mesh positioning: Inspect the mesh before pouring to confirm that it remains stable and at the specified height.

Wire mesh and rebar are both used to reinforce concrete, but they serve different purposes depending on the project. Wire mesh consists of interconnected steel wires arranged in a grid, while rebar uses individual steel bars to provide reinforcement. 

Understanding their differences helps you choose the right option for concrete slabs, driveways, foundations, and other construction applications.

• Strength and load capacity: Rebar is generally preferred for structural applications requiring higher tensile reinforcement.

• Crack control: Wire mesh helps distribute reinforcement across concrete slabs to control cracking caused by shrinkage and temperature changes.

• Installation: Wire mesh is typically easier to install over large, flat areas, while rebar often requires more cutting, bending, and tying.

• Cost: Wire mesh may reduce installation labor for simple slabs, whereas rebar costs depend on bar sizes, spacing, and project complexity.

• Common applications: Wire mesh is often used in floors and pavements, while rebar is common in foundations, beams, columns, and heavily loaded concrete structures.
