How do you know the true and false purchase of Security mesh?
One looks from the outside.
The good Security Screen Mesh surface is smooth, evenly sprayed, finely processed, and weaving is particular. However, the relatively inferior Security Screen Mesh production is not standardized, it seems that it can be seen relatively rough.
1, the mesh is even: high quality good Security Screen Mesh, its mesh is even, the distance between the grid is the same, the quality of the mesh hole size of the inferior product, it seems to give people a bad feeling.
2, diagonal: foreign trade standard The entire diagonal of the two meshes does not exceed 5mm, the domestic sales standard does not exceed 1cm, exceeds the standard, the net is completely irregular quadrilateral, after being mounted on the screen, the aesthetic degree is reduced, let When people look at it, they feel that they are inferior.
3, spray: high-quality diamond mesh spray evenly, there will be no hole blocking, leakage spray, the overall color of the mesh is inconsistent

2, take a sample to the local quality supervision bureau to test the content of nickel and chromium.
3, polished with an angle grinder, 201 material carbon content is higher than 304, grinding is more than 201 sparks and dispersion, 304 material sparks scattered and less.
4. The element content is measured by a spectrometer, and the nickel content of 304 is 8% or more.
