Filter effect of stainless steel mesh

At present, I want to buy a batch of stainless steel mesh. Among the many products, I do n’t know which kind of mesh to choose. Some people suggest to buy a mat type mesh because its warp and weft structure are different.
The intricate but regular mesh can have unexpected results It can take care of many impurities that cannot be filtered by the grid. Besides the high temperature resistance, what kind of function does the mat type net have?

It was discarded after one week of use. Therefore, all the items are mainly stainless steel. The seat net is made of stainless steel. It meets our work requirements. What functions does it have in addition to high temperature resistance?
According to my own understanding, its other advantages are acid resistance and alkali resistance, which is very suitable for our job requirements. The mat type mesh is not only resistant to high temperature, but also acid and alkali, and is suitable for petrochemical, chemical, fertilizer and other industries.
