Guide to Identifying Stainless Steel Mesh Types
Stainless steel mesh is categorized by manufacturing processes.
1. Stretched Mesh
Manufactured through stamping/stretching of stainless steel sheets, this type (also called perforated or expanded metal mesh) features uniform apertures. Common applications include elevator treads, mining screens, and highway barriers. Its surface integrity remains intact during processing.
2. Flat-Top Screen Mesh
Crafted from high-carbon/manganese steel, this variant excels in wear resistance. Key advantages over standard steel mesh:
- Withstands temperatures exceeding 300°C
- 40% higher shock/tensile resistance
- 15-20% improved open-area ratio
Primarily used in aggregate sorting and asphalt plants.
3. Corrugated Screen Mesh
Available in two configurations:
- Monofilament: Thicker wires (0.8-2.5mm) with small apertures (2-8mm) for precision screening
- Dual-Wire: Finer wires (0.5-1.2mm) create larger openings (10-25mm), offering 30% better elasticity at lower cost
4. Crimped Wire Mesh
Woven from pre-crimped wires (stainless/galvanized steel) in three patterns:
- Bidirectional wave
- Bidirectional bend
- Unidirectional bend
Widely used in chemical filtration and structural reinforcement. Note: Hot-rolled vs cold-rolled processing affects mesh flexibility.
