Inspection methods for determining whether welded wire mesh production is qualified

There are many manufacturers of welded wire mesh, but some produce qualified products while others do not. Many substandard welded wire meshes remain on the market. So, how do we determine if the welded wire mesh we purchase is qualified?

1. For qualified welded wire mesh, the exposed ends on both sides should not exceed 2mm. The intersections of the warp and weft wires must be firmly welded. However, for a secure weld at the edges, the weft wires must protrude slightly, but not excessively; generally, an extension of no more than 2mm is acceptable.

2. Other surface characteristics include uniform mesh size and a uniform hot-dip galvanized layer to ensure effective corrosion resistance.

3. The wire diameter error should be controlled within 0.02mm. For example, if you purchase welded wire mesh with a wire diameter of 89 mils, measure the diameter with a micrometer. The permissible diameter range is 87-91 mils. Mesh within this range is considered qualified. Because the precision is relatively high, but no one can control it perfectly during the production process, welded wire mesh can be accurate to 0.01 mm, so errors are acceptable.

4. The tensile strength of welded wire mesh must reach 120N; otherwise, it is considered substandard. There is no simple method to test the tensile strength of welded wire mesh; it can only be verified through professional tools and expert testing, which we will not go into detail about here.

In summary, this is an introduction to identifying whether welded wire mesh production is qualified. We believe that through our professional explanation, you will be able to distinguish between them.
