Stainless steel expanded metal mesh is a mesh material made from stainless steel plates such as 302, 304, and 316 through a stamping and stretching process. It is also known as stainless steel stretched mesh or expanded metal mesh.
Other names include stainless steel expanded mesh, stainless steel punched and stretched mesh, stainless steel stretched mesh, and stainless steel diamond mesh. The main standards implemented include GB/T 11953-89 and HG/T 21559.3-2005.
Selection of stainless steel expanded metal mesh requires a comprehensive evaluation based on material characteristics, application scenarios, and technical parameters. In terms of material, 304 stainless steel (Cr18Ni9) is suitable for ordinary corrosive environments, while 316 stainless steel (Cr16Ni12Mo2), due to its molybdenum content, has better salt spray resistance and is suitable for highly corrosive environments such as marine environments. Regarding technical parameters, the aperture (e.g., 2-10mm) determines the filtration/ventilation efficiency, the wire diameter (0.5-3mm) affects the load-bearing strength, and the open area ratio (30%-70%) is related to fluid permeability.
Industrial filtration prioritizes high-precision (pore size ≤ 1mm) and high adsorption capacity (e.g., 51.4mg/g) fine-mesh filters, while architectural filtration focuses on the aesthetics of surface treatment (polishing/brushing). Installation must be compatible with the strength of the supporting structure (e.g., load ≥ 50kg/m²).
