Expanded Metal Filters

Expanded metal filters from Anping Gaite Wire Mesh Co., Ltd. are manufactured by shearing and stretching solid metal sheets into a continuous pattern of diamond-shaped or square apertures, eliminating welded joints and enhancing structural integrity. The base materials include stainless steel, galvanized steel, aluminium, and tinplate, with thicknesses ranging from 0.5mm to 3.0mm as specified in the source. The resulting mesh has uniform openings with typical pitch sizes between 2mm and 25mm, depending on the application. These filters are designed for mechanical strength and resistance to deformation under pressure, making them suitable for high-velocity fluid and particulate filtration environments.

The filters are commonly used as support layers for composite media such as woven wire mesh, carbon fiber, or Filtafoil aluminium foil, which are layered to capture fine dust, grease, or moisture. Standard thicknesses for filter panels range from 7mm to 50mm, with infill materials including Bondina and galvanized steel. Unlike welded mesh, expanded metal retains full sheet continuity, reducing failure points under thermal cycling or vibration. The material grade is typically 304 or 316 stainless steel where corrosion resistance is required, or ASTM A653 for galvanized variants, though exact grade must be confirmed per order.

These filters serve industrial air filtration systems, HVAC vent ridges, domestic heating unit cartridges, and liquid filtration housings. Buyers include manufacturers of commercial air purifiers, automotive cabin filters, and process equipment suppliers. Packaging is typically bulk cartons or wooden crates, with custom shapes formed via stamping or bending using in-house tooling. Lead time and minimum order quantities are not specified and must be confirmed directly with the supplier. Incoterms are negotiable but commonly FOB Tianjin or CIF destination port.

Anping Gaite Wire Mesh Co., Ltd. operates from Anping County in Hebei Province, a known hub for metal mesh manufacturing in China. The company has in-house tooling capabilities for custom forming and shapes, indicating direct control over die design and production flexibility. Its address is listed as Youlin International City, suggesting a commercial-scale facility with warehousing and logistics infrastructure. The listing does not specify production volume, workforce size, or years in operation, and no certifications such as ISO or CE are referenced.

The supplier focuses on expanded metal filters and formed filtration components, including vent tiles and bullet filters for heating systems. It offers custom panel assemblies with frames and backing meshes, implying capability in secondary fabrication. There is no mention of export history, client names, or quality testing protocols beyond material descriptions. Response rate and average response time are not recorded, indicating no active customer service channel on the platform. The supplier’s reliability must be verified through direct communication and sample requests.
