From which aspects does Dashang test the quality level of crimped wire mesh?

Generally, crimped woven wire mesh is a heavy-duty mesh with relatively thick wire diameters and mesh sizes ranging from 1mm to 50mm. Inspecting crimped wire mesh can be approached from the following aspects:

1. Mesh size error: average error controlled within ±5%;

2. Wire diameter error: average error controlled within ±2%;

3. Weaving strength, diagonal error, and flatness;

4. Chemical composition of raw materials, steel mill material certificate, and traceability of raw materials. 

5. Length, width, and net weight of the woven mesh;

Dashang Wire Mesh manufactures and sells crimped metal wire mesh. Every product undergoes testing. Below is a demonstration of the product testing process for stainless steel crimped wire mesh:

During the production process of stainless steel crimped wire mesh, the stainless steel wire undergoes cold working deformation (first crimping, causing the stainless steel wire to bend, then weaving), making its internal crystal structure unstable. This leads to the consumption and destruction of the oxide film on the stainless steel woven mesh, reducing its corrosion resistance, and even causing surface rust. This is where the quality of raw materials from steel mills becomes apparent. Even using the same austenitic 304 stainless steel, high-quality stainless steel wire maintains a stable crystal structure after cold working, its oxide film is less prone to cracking, exhibits excellent corrosion resistance, and has a smooth, rust-free surface. Inferior stainless steel wire, while meeting chromium and nickel content standards, is highly susceptible to stress corrosion after rolling and weaving due to deviations in other components or higher levels of impurities, thus affecting its service life. Therefore, selecting high-quality raw materials from reputable steel mills is crucial for ensuring the long-term corrosion resistance of stainless steel crimped wire mesh. Dashang Wire Mesh strictly selects austenitic stainless steel raw materials from well-known steel mills such as Qingshan, and conducts spectral analysis on each batch of raw materials to ensure that the content of core elements such as chromium, nickel, and molybdenum meets national standards.

Meanwhile, crimped woven wire mesh should be stored in a dry, well-ventilated environment, avoiding contact with acids, alkalis, and salts to prevent surface corrosion. It should be stored off the ground and not directly piled on the ground or in open areas to prevent moisture damage. During transportation, it should be covered with a rainproof tarpaulin to prevent rain and moisture absorption. Finished wire mesh should be stacked flat and should not be folded or subjected to heavy pressure to avoid deformation of the mesh or damage to the wire diameter, which would affect its performance. Before leaving the factory, Dashang Wire Mesh conducts a full inspection of each roll of crimped wire mesh, focusing on checking the uniformity of the mesh openings, the consistency of the wire diameter, and the surface smoothness. All test data is archived and traceable.

Dashang offers a variety of options for wire diameter (0.5mm-5mm), mesh size (1mm-50mm), and size (standard or customized).
