304 Stainless Steel Wire Mesh Screen
304 stainless steel wire mesh screen is one of the most commonly used wire mesh products in the field of filtration and screening. SS304 is also known as 18-8 stainless steel, contains 18% chromium and 8% nickel. It is a recognized food-grade stainless steel and is widely used not only in the food industry, but also in the petrochemical industry. However, higher grade 316 stainless steel mesh should be considered in marine environments or in liquids containing chloride ions.
Types of 304 Stainless Steel Mesh Screen
The following summarizes the common types of 304 stainless steel mesh, and the appropriate type can be selected according to the purpose and cost.
304 stainless steel woven wire mesh: the manufacturing process of stainless steel woven mesh is similar to a loom, which is a metal mesh product made by interweaving stainless steel wires of warp and weft with a weaving machine. It is sometimes called wire cloth because the mesh woven with fine wire diameters can be rolled up like cloth. The common weaving methods of woven wire mesh are plain weave, twill weave and Dutch weave, which are mainly used for screening and filtration.
Stainless steel welded wire mesh is a grid metal with square or rectangular openings formed by an automatic electric welding machine consisting of a row of multi-electrode welding a series of weft wires on pre-laid warp wires. There are strong welded joints at the intersection of each warp and weft. The wire mesh which usually has an opening of 3-25mm and can be easily rolled up, is common in hardware stores, so it is also called hardware cloth.
Stainless steel perforated metal mesh is a metal sheet product with a pattern consisting of holes. A perforated metal punches a series of holes in sheet metal to create a specific pattern. Common hole types include round holes, square holes, slotted holes, hexagonal holes, etc., of which round holes are the most common and economical type.
Expanded metal mesh has diamond-shaped openings, so it is also called diamond mesh. This diamond opening is cut and stretched by a row of V-shaped knives of a machine through reciprocating motion. The initial mesh surface is raised, which is called raised expanded metal. Further processing with rollers can flatten the surface of the mesh, known as flattened expanded metal.
Crimped wire mesh is usually first rolled straight steel wire into corrugated shape by machine with gear molds, and then crimped wire is woven into metal mesh by hand or machine.
