Expanded metal mesh is an integral, high-strength structural support material widely used for both inner lining and outer protection of industrial filter elements. Formed by one-piece slitting and stretching process without welding or loose wires, it features a tough diamond pore structure, excellent rigidity and stable shape retention. It serves as reliable internal backing for filter media and sturdy external protective skeleton for finished filter cartridges, balancing great permeability and structural stability. It is a versatile, cost-effective support solution for various hydraulic, industrial and chemical filtration systems.

Typical Applications

✅ Inner liner support for pleated filter cartridges

✅ Outer protective skeleton for industrial filter elements

✅ Structural reinforcement for hydraulic and lubrication filters

✅ Support framework for water treatment and chemical filtration equipment

✅ Shaping and protection for custom cylindrical filter components

Expanded metal mesh is a dedicated structural support material optimized for full-structure protection of filter elements, supporting both internal lining and external wrapping installation. Different from woven mesh and perforated plate, it adopts an integral stretching molding process, featuring an uninterrupted metal framework with uniform diamond openings. This unique structure delivers perfect combination of high mechanical strength and high open area, avoiding wire loosening, poor permeability and excessive weight of other filter support materials.

As inner filter lining support, it provides uniform and stable backing force for pleated filter media. It effectively supports filter pleats, maintains consistent spacing, and prevents media collapse, shrinkage and deformation under long-term fluid pressure and flow impact, ensuring complete filtration area and stable working efficiency.

As outer filter protection, the rigid integrated structure acts as a tough outer guard, resisting external mechanical extrusion, equipment friction and accidental impact. It locks the overall filter outline, prevents filter bulging, layer separation and structural damage in complex industrial environments.

Key Advantages

· Dual-Scenario Adaptability: Professionally applicable for both inner media support and outer filter protection, meeting all-round structural stabilization needs of filter elements.

· Integrated Deformation-Resistant Structure: One-piece forming without loose wires or solder joints, no unraveling or structural loosening during long-term operation.

· High Permeability & Low Resistance: Standard diamond open structure ensures smooth fluid passage, minimizes pressure drop and does not affect filtration throughput.

· Effective Media & Structure Protection: Smooth burr-free surface protects fine filter media from scratching and wear, while rigid framework shields filters from external mechanical damage.

· Lightweight & High Toughness: Lighter than perforated plate with better flexibility, easy to roll, bend and form into various filter cartridge shapes.

· Excellent Environmental Adaptability: Available in galvanized steel, carbon steel and stainless steel, with great corrosion and wear resistance for diverse harsh working conditions.
