Welded Wire Basics

Banker Wire is the leading manufacturer of welded wire mesh in North America. Our dedication towards satisfying the customer fuels our focus on becoming your primary manufacturing partner. Specializing in small to large production runs, our manufacturing flexibility remains unmatched in the welded wire mesh industry. Banker Wire's manufacturing culture ensures that our customers always receive the highest quality product with an unbeatable value.

What is Welded Wire Mesh?

Welded wire mesh is constructed with two orthogonal wires that are joined together at their intersections using a resistance welding process to form a grid. The line wires of the grid are guided through the welder using a pattern board. The machine drops cross wires into place and fuses them together to create the two distinctive planes that form welded wire mesh.

At Banker Wire we currently utilize five fully automated CNC grid welding machines and two CNC jig welders that allow us to produce to your exact specifications. Sheet sizes can be up to 78” wide and 240” long (dependent on mesh spacing). Wire spacing and diameter configurations are nearly endless, allowing us to be the top manufacturing partner for custom welded wire mesh.

Below in the next several sections of this page, you will find more detailed information on the basics of welded wire mesh and topics to take into consideration when ordering your specifications. Our knowledgeable staff is available to assist you with any questions you may have.

Materials for Welded Wire Mesh

Raw Materials: Welded wire mesh is utilized in a variety of settings that may require a high degree of performance in strength or corrosion resistance. Because of that, Banker Wire offers welded wire mesh in plain steel, pre-galvanized, stainless steel, and galfan. For more detailed information on these materials, please visit our Materials resource page.

Secondary Finishes: At Banker Wire, all of the products that we offer are manufactured in a bare, mill-finished condition. A secondary finish may be desired to protect the welded wire mesh, or to enhance a specific aesthetic. For welded wire mesh we can facilitate powder-coating and hot-dipped galvanizing if desired.

Welded Wire Spacing

Welded wire mesh spacing can be expressed by measuring from the center of two wires (Center to Center) or by measuring the opening between two wires (Clear Opening). We can manufacture standard and custom welded wire mesh with a spacing range of a minimum of 1” to as large as may be required.

Welded Wire Diameter

Welded Wire DiameterBanker Wire manufactures welded wire mesh with a wide variety of wire diameters ranging from .080” to .375”. For accuracy, the wire diameter should be expressed in decimal format and not expressed as a gauge.

Edge Conditions

Banker Wire Welded Wire Mesh has two standard edge conditions: trimmed and untrimmed.

Trimmed: When ordering welded wire mesh with Trimmed Edges, wire overhang will be 1/8" or less on three sides with Standard Heat Thumbnailing* on the fourth side. The final spacing around the perimeter may be reduced and balanced when necessary to stay within the dimension ordered.

Trimmed Welded Wire Mesh Trimmed Welded Wire Mesh

Untrimmed: When ordering standard Untrimmed Edges, the welded wire mesh will have approximately full tails. This means that the outer wire overhang will be approximately equal to that of the wire mesh spacing, with Standard Heat Thumbnailing* on the back side. The tail length can also be customized to suite applications as needed.

* Standard Heat Thumbnailing often occurs when welded wire mesh is tightly spaced. Further explanation is provided in the next section.

Standard Back Gain

Standard Back Gain is a natural occurrence in the welded wire mesh process that is caused by the heating and cooling of the mesh as it is welded into place. It is more common in wire mesh that is tightly spaced. Standard Back Gain is demonstrated in the drawing below. In the drawing below, sides A, B, and C represent a standard 1/8" trim while side D represents Standard Back Gain.

Please note: that the Standard Back Gain is exaggerated in this drawing to more clearly demonstrate the phenomenon.

Quality and Testing

Banker Wire manufactures to a strict set of internal standards that guarantee the welded wire mesh is produced to the highest possible quality and consistency. There are 11 different quality checks that we use to test dimension, squareness, and strength; these checks are performed and documented throughout the production run. The two tests shown below are used to check strength characteristics of our welded wire mesh.

Torque Test: To ensure that there is a strong weld at each intersection, the operator will attempt to break that weld using a torque tool. The torque tool is calibrated per a set of internal standards but can also be calibrated to any requested standard. This test is performed at set intervals to verify consistency throughout the production run.

Weld Set-Down Test: Weld-Set Down is a percent reduction in the overall thickness of the two wire diameters being fused together with an electric current. This test is performed to make certain that our welding machinery is functioning properly and consistently throughout the production run. A digital micrometer is used to record and store the height of the welded intersections across the width of the sheet.
