3. Manufacturing Process—From Raw Sheet to Advanced Filter Screen
1. Raw Material Selection: High-quality stainless steel expanded sheet begins with SS304/316/316L coils, certified per ISO 9001 for composition, surface finish, and mechanical integrity.
→
2. Expanding & Slitting: Sheets are simultaneously slit and stretched via CNC press technology, ensuring consistent strand width and opening pattern per ASTM E2016.
→
3. Forming & Shaping: Custom molds, rolling, and laser cutting shape the mesh into cylinder or bowl forms, as required by Bowl Filter Screens. Precise dimensional tolerances ensured by ANSI/ISO protocols.
→
4. Surface Treatment: Degreasing, passivation, and—where specified—anodizing or powder coating to enhance corrosion resistance; all compliant with ASTM A967 and FDA requirements.
→
5. Final Inspection & Testing: Dimensional, mechanical strength, and flow performance tests per ISO 9001. Batch traceability, documentation, and physical marking.

4. Technical Advantages: Why Choose Stainless Steel Expanded Sheet?
- Superior Corrosion Resistance: Stainless alloys withstand harsh chemicals and water—optimal for filtration, water treatment, and outdoor architectural mesh.
- High Mechanical Strength: Expanded structure increases rigidity without significant weight addition; strand and bond configuration resists deformation under load.
- Controlled Open Area: Fine-tuned mesh geometry ensures balance between filtration efficiency and maximum fluid/gas flow rate.
- Eco-Friendly Production: Waste-free expansion process maximizes material utilization; recyclability of stainless steel reduces lifecycle footprint (Stainless Steel World).
- Design Versatility: Broad range of decorative and industrial patterns possible, supporting custom branding (especially in decorative aluminum mesh solutions).
- Long Service Life: Typical life 10–15 years, minimizing replacement and downtime in critical industry applications.

A: Aluminum mesh prioritizes lightweight and corrosion-resistance for facades/ceilings but lower mechanical strength; stainless steel is superior in structural rigidity, lifespan, and high-pressure filtration.
A: Dimensional inspection, salt spray test (>48h/120h per ASTM B117), burst/hydrostatic strength, digital mesh/photo verification, 3rd-party analysis as needed.
A: Yes—using modular CNC press and laser cutting, any diameter, height, or special bowl contour can be produced to customer’s supplied drawings.
A: Install with flow direction aligned to main strand; seal with EPDM or PTFE rings; ensure no mesh distortion during clamping for optimized sealing.
A: Professional powder-coating or anodizing (for aluminum) typically preserves—sometimes enhances—surface passivation, provided treatments follow ASTM/ISO guidelines.
