Heavy-Duty Welded Wire Mesh for Concrete Reinforcement
In the demanding world of modern construction, the integrity of concrete structures is paramount. Our high-strength Welded Wire Mesh is engineered specifically for concrete reinforcement, offering a superior, time-saving alternative to traditional loose rebar. This prefabricated grid of welded steel wires provides exceptional tensile strength, crack control, and dimensional stability, making it an indispensable component for durable slabs, walls, and precast elements. Designed for efficiency and reliability, our mesh ensures your wire mesh concrete projects meet the highest standards of safety and performance.
Product Overview
Our Welded Wire Mesh for concrete is a factory-manufactured reinforcement material created by resistance-welding longitudinal and transverse steel wires at precise intersections. This process creates a rigid, uniform grid that is easily placed within concrete formwork. It is primarily used to resist tensile stresses, control shrinkage cracking, and distribute loads evenly across a concrete surface. As a key element in wire mesh concrete systems, it simplifies construction logistics, reduces labor costs, and enhances the overall structural behavior of the finished concrete element, from industrial floors to residential foundations.
Key Features
- High-Strength Welded Joints: Each intersection is electronically welded to ensure consistent strength and prevent slippage under load, maintaining grid integrity during concrete placement.
- Uniform Grid Pattern: Precisely spaced wires provide predictable and even reinforcement distribution, leading to superior crack control in the hardened wire mesh concrete.
- Corrosion Resistance: Available in various finishes including plain (uncoated), galvanized, and epoxy-coated to suit different environmental exposures and project specifications.
- Easy Handling & Installation: Supplied in rolls or flat sheets, the mesh is lightweight and can be quickly unrolled, positioned, and tied, significantly accelerating project timelines.
- Excellent Bond with Concrete: The ribbed or deformed wire surface ensures optimal mechanical bond with the concrete matrix, allowing for efficient stress transfer.

Frequently Asked Questions (FAQ)
What is the difference between welded wire mesh and rebar in concrete?
Welded wire mesh is a prefabricated sheet of welded wires, while rebar consists of individual steel bars. Mesh is typically used for thinner sections (like slabs) for crack control, offering faster installation. Rebar is used for heavier structural elements (like beams and columns) where higher tensile strength and custom bending are required. They are often used together in complex structures.
Should wire mesh be placed in the middle or bottom of a concrete slab?
For ground-supported slabs (e.g., floors on grade), wire mesh should be positioned in the upper third of the slab to effectively control shrinkage cracks that start at the surface. It is typically raised on chairs or supports. For structural slabs, placement is determined by engineering design to resist specific tensile forces.
How do I choose between galvanized and plain wire mesh?
Plain (black) steel mesh is cost-effective for interior applications or concrete with sufficient cover in non-aggressive environments. Galvanized mesh is essential for exterior applications, in coastal areas, or where de-icing salts are used, as the zinc coating provides a critical barrier against corrosion, ensuring the longevity of your wire mesh concrete structure.
Can your wire mesh be customized?
Absolutely. We specialize in custom fabrication. You can specify the exact wire diameter, mesh spacing (longitudinal and transverse), sheet/roll dimensions, and steel grade to meet your project's specific structural calculations and drawings.
What certifications do your products hold?
Our production is compliant with major international standards including ASTM, BS, and ISO. We provide Mill Test Certificates (MTCs) or Certified Test Reports (CTRs) with each shipment, detailing the chemical and mechanical properties of the material for your quality records.
