The surface condition of woven wire mesh can vary depending on the material, manufacturing process, and handling. It is essential to consider the surface condition for specific applications, as it can affect the mesh’s performance, appearance, and compatibility with other materials. Here are some common surface conditions for woven wire mesh:
Clean and bright: This is the most desirable surface condition for many applications, especially those requiring a visually appealing appearance or high cleanliness standards. The wire mesh has a smooth, shiny surface free of dirt, grease, or oxidation.
Lightly oxidized: Some wire mesh materials, such as stainless steel, may have a thin layer of oxidation on the surface. This is typically not a concern for most applications, as the oxidation layer can provide additional corrosion resistance.
Grease or oil coating: During the manufacturing process, some wire mesh may be coated with a thin layer of grease or oil to protect it from corrosion or to facilitate weaving. This coating can be removed by cleaning the mesh with a suitable solvent or degreaser if necessary for the intended application.
Mill finish: This surface condition refers to the appearance of the wire mesh as it comes off the production line. It may have some minor surface imperfections, such as scratches, tool marks, or slight discoloration. Mill finish is generally acceptable for most applications, but it may not be suitable for those requiring a high level of surface quality or aesthetics.
Passivated: Stainless steel wire mesh can be passivated to remove any surface contaminants and enhance its corrosion resistance. Passivation involves treating the mesh with an acid solution, typically nitric or citric acid, which removes free iron and other contaminants from the surface and promotes the formation of a protective chromium oxide layer.
