Multi-layer sintered woven wire mesh is a versatile and high-performance filter material known for superior mechanical strength, precise filtration capabilities and excellent resistance to heat and corrosion. This ss mesh is made by laminating multiple layers of woven wire mesh through a sintering process at high temperatures. Sintered stainless steel mesh offers a robust and durable structure with uniform pore sizes, high filtration accuracy and mechanical stability. Common types of multi-layer sintered wire mesh include 3-layer and 5-layer configurations.

Application: Multi-layer sintered ss mesh is commonly used in chemical processing, pharmaceuticals, aerospace and water treatment, providing effective separation and purification of fluids and gases.

Popular Layer Types:

• 3-Layer Sintered Wire Mesh: 3-layer sintered wire mesh features a fine mesh layer for precise filtration, sandwiched between two coarser support layers that provide exceptional strength. Mainly for applications requiring a robust filter media. Common uses include filtering liquids with moderate particle loads or gaseous environments. If you need a reliable filter screen that excels in both strength and efficient filtration, sintered 3-layer ss mesh is a good choice.
• 5-Layer Sintered Wire Mesh: 5-layer sintered wire mesh offers a more versatile solution compared to its 3-layer. This multi-layered design strikes a balance between strength, filtration accuracy, and flow management. 5-layer sintered stainless steel mesh is mainly used for processing fine particles, high-purity liquids, or corrosive fluids. The additional mesh layers provide enhanced performance for applications requiring higher precision and protection from harsh environments.
