Corrosion resistance remains another significant challenge, particularly when processing acidic foods or using aggressive cleaning chemicals. While stainless steel alloys offer good resistance, they may not be sufficient for all food processing environments, leading to premature degradation of the mesh structure and potential contamination concerns.

The balance between mesh aperture size and structural strength presents ongoing engineering challenges. Finer mesh sizes required for certain applications often compromise the mechanical strength needed to withstand industrial processing conditions. This limitation becomes particularly evident in high-throughput operations where mechanical stress is considerable.

Cleaning and sanitation of metal mesh components also present technical difficulties. The complex geometry of mesh structures creates numerous crevices where food particles and microorganisms can accumulate, making thorough cleaning challenging. This issue is compounded by the need for cleaning protocols that effectively remove residues without damaging the mesh or leaving chemical residues.

Emerging challenges include the need for metal mesh materials that comply with increasingly stringent food safety regulations while maintaining performance characteristics. Additionally, the industry faces growing pressure to develop mesh solutions that reduce energy consumption and environmental impact without compromising processing efficiency or product quality.
