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 square mesh spacing range from 1” to as large as may be required. Rectangular mesh spacing ranges from 1/2″ x up to as long as may be required.
Banker Wire manufactures welded wire mesh with a wide variety of wire diameters ranging from .105” to .375”. For accuracy, the wire diameter should be expressed in decimal format and not expressed as a gauge.
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.
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 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.
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. Throughout each production run, panels are checked for dimension, squareness, and strength to ensure that every panel meets our standards and is exactly the same as the one before it. The two tests shown below are used to check strength characteristics of our welded wire mesh.
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.
Banker Wire strives to manufacture the highest quality woven wire mesh on the market today. As there is a lack of ASTM standards for welded wire mesh, we have developed a set of standard measurements and tolerances for our welded wire mesh products. Our tolerances have been determined from historical product manufacturing and are being tested and improved upon constantly to ensure the best wire mesh possible.
