How Is Steel Reinforcing Mesh Made?

Steel reinforcing mesh is a critical component in concrete construction, providing the structural strength needed for long-lasting results. But how is steel reinforcing mesh made? At Neumann Steel, we manufacture high-quality reinforcing mesh right here in Australia, using advanced processes and strict quality control to meet industry standards. 

With over 50 years of experience, our team delivers certified products trusted by concreters, builders, large government agencies and developers across the East Coast. 

Let’s take a closer look at how reinforcing mesh is made – from raw material to ready-to-use product, and what makes our manufacturing approach unique.

From Raw Steel To Reinforcing Mesh

Creating reinforcing mesh starts with steel wire rods, which we source from Australian mills to ensure consistent quality and traceability. These rods are typically produced through a hot rolling process, where heated billets are rolled through a series of progressively smaller grooves to achieve a set diameter.

The key stages in mesh production 

Wire drawing

A cold working process, steel rods are pulled through a series of progressively smaller dies. This action reduces the wire’s diameter to the specific size needed for reinforcement, while simultaneously increasing its length. This process also work-hardens the steel, enhancing its tensile strength and improving its mechanical properties. Lubricants are often used to reduce friction and heat generated during drawing.

Ribbing

The smooth wire is then “ribbed” or deformed with ridges to improve its bond with concrete. This crucial step involves passing the drawn wire through special rolling mills that create a series of ridges or indentations on its surface. These deformations are vital as they significantly improve the mechanical bond between the steel mesh and the concrete when it’s used for reinforcement. They help prevent slippage and enhance the overall strength of the concrete structure.

Straightening and cutting

Next, the wire is straightened and cut to the required lengths. This ensures that each wire segment is uniform, which is essential for the accuracy and quality of the final mesh product. For more detail on handling the product after it’s made, learn how to cut and bend steel reinforcing mesh and bar.

Welding

Now, we form mesh sheets. The straightened and cut wires are meticulously arranged in a grid pattern, with longitudinal (line) wires and transverse (cross) wires placed at precise intervals. These intersections are joined using electric resistance welding. This process involves applying an electric current and pressure to the contact points, generating heat that melts and fuses the wires together without the need for additional filler material. This method ensures strong, durable connections that are crucial for the integrity and performance of the reinforcing mesh in concrete applications.

This meticulous manufacturing process, from the initial steel rod to the final welded mesh, ensures that the product meets stringent quality standards and provides reliable reinforcement for various construction projects.

Types Of Reinforcing Mesh We Manufacture

We produce a wide variety of steel reinforcing mesh options tailored to different applications.

Each mesh type is manufactured to suit specific structural needs and design requirements. Our team can assist you with custom mesh sizes, bar spacing, and sheet dimensions for large-scale projects or complex designs.

Quality Control And Certification

All our reinforcing mesh undergoes rigorous testing throughout the manufacturing process. Our quality assurance protocols include:

• Tensile strength testing
  
• Weld shear strength checks
  
• Dimensional accuracy
  
• Traceability of materials
  

Our mesh is certified under Australian Standard AS/NZS 4671, and each batch is tagged with identification for on-site verification. This gives you confidence in product performance, safety, and compliance with project specifications.

Sustainability In Mesh Manufacturing

We’re committed to minimising environmental impact at every stage of manufacturing. We integrate sustainability into our mesh production by:

• Sourcing steel from Australian suppliers with certified sustainable practices
  
• Reducing waste through recycling and efficient wire cutting processes
  
• Minimising transport distances by supplying mesh from strategically located plants
