How To Judge Whether The Welded Wire Mesh Is A Qualified

As a Welded Wire Fencing exporter,there are many manufacturers of welded wire mesh, but some products produced by some manufacturers are not qualified. Welding nets is also called quality  Welded Wire Mesh Cable Tray that cannot provide inspection certificates for welded wire meshes will still be exiled to the market. Then, how do we identify whether the welded wire mesh produced is qualified when we purchase the welded wire mesh? Below we introduce from a few points

1. The error of quality  Welded Wire Mesh Cable Tray diameter is controlled to 0.02mm. For example, we purchased a welded wire with a wire diameter of 89 wires. We measured the diameter with a micrometer. The allowable diameter range was 87-91 wires. Within this range is a qualified welded wire mesh. Because the accuracy is over, but in the production process who can not control so good, welded wire mesh can be accurate to 0.01 mm, so the error is allowed.

2. The tensile strength of the quality  Welded Wire Mesh Cable Tray should reach 120N, otherwise it will be unqualified welded wire mesh. There is no simple way to test the tensile strength of the welded wire mesh in this respect. It can only be tested by professional tools and expert tests. We will not introduce it in detail.

3. The exposed side of the welded wire mesh can not exceed 2MM. It is a qualified welded wire mesh. Welding wire wire and weft wire should be welded firmly at the place, but the welding wire edge to be welded firmly weft must be out of some, in order to weld firmly, but can not come out too much, generally not more than 2 mm welded wire mesh is qualified welding network.

4. There are some surface phenomena: the mesh should be uniform, and the galvanized welded wire mesh hot-dip galvanizing layer should be uniform so that the anti-corrosion effect can be guaranteed.

The material of the welded wire mesh used in the project is also different. It is divided into hot-dip galvanized welded wire mesh, cold-galvanized welded wire mesh, and wire-welded welded wire mesh. Among them, the harder wire is welded wire mesh, which is more difficult than the first two. To be large, the hot-dip galvanized welded wire mesh is the easiest to construct, and the flexibility is better. After tiling, it should be flat and easier to hang.The standard welded wire mesh sizes are various.
