Stainless Steel Expanded Metal Mesh: Material & Construction
- Premium Stainless Steel Grades:
- 304/304L: General-purpose corrosion resistance (PREN ≥18) for food processing equipment or architectural cladding (apertures: 2–50 mm).
- 316/316L: Enhanced chloride resistance (PREN ≥25) for marine applications, chemical filtration, or offshore platforms (slot sizes: 1–30 mm).
- Duplex 2205/2507: High strength (550–800 MPa yield) and pitting resistance (PREN ≥35) for desalination plants or oil refinery grating.
- 310/S31254 Super Austenitic: Extreme temperature stability (up to 1,100°C) for furnace components or exhaust systems.
- Precision Engineering:
- Diamond/Hexagonal Patterns: Uniform apertures (5–100 mm spans) with 15–70% open area for structural support or ventilation.
- Strand Thickness: Ranges from 0.5–6 mm for lightweight screening decks or heavy-duty industrial flooring.
Stainless Steel Expanded Metal Mesh: Performance Advantages
- Superior Corrosion Resistance:
- Salt Spray Resistance (1,500+ hours, ASTM B117): Ideal for coastal infrastructure or shipbuilding.
- Acid/Alkali Tolerance (pH 1–13): Withstands chemical processing or wastewater treatment environments.
- Structural Integrity:
- High Tensile Strength (500–800 MPa): Supports ≥10 kN/m² loads in walkways or machine guards (EN 1993-1-3 compliant).
- Fatigue Resistance: Maintains integrity under vibrational stresses in mining screens or HVAC ducting.
- Hygienic & Aesthetic Versatility:
- Electropolished Finish (Ra ≤0.8 µm): Meets EHEDG/3-A Sanitary Standards for dairy processing or pharmaceutical sieves.
- Architectural Finishes: Brushed, powder-coated, or PVDF-laminated for modern façades or interior design.
Precision Manufacturing & Quality Assurance
- Advanced Fabrication Methods:
- Laser-Guided Expansion: Ensures ±0.1 mm aperture tolerance (ISO 9013 compliant) for precision filtration or solar panel backing.
- TIG Welding: Seamless integration into custom grating systems (ASME Section IX certified).
- Rigorous Testing Protocols:
- Intergranular Corrosion Testing (ASTM A262): Validates resistance to sensitization in welded structures.
- Load-Bearing Certification: Tested to EN 13561 for safety barriers or balcony mesh panels.
- Hygienic Surface Testing: Passes ATP swab tests for food-grade applications (FDA 21 CFR 177.1520).
- Custom Solutions:
- Perforated-Expanded Hybrids: Combines airflow and strength for acoustic panels or industrial filters.
- Reinforced Edges: Hemmed or welded frames for modular flooring systems or machine enclosures.
Stainless Steel Expanded Metal Mesh: Industry Applications
- Food & Beverage:
- Sorting Conveyors: 316L mesh (3 mm apertures) for vegetable washing lines (3-A compliant).
- Brewery Mash Tuns: Electropolished 304 mesh (2 mm strands) for grain separation.
- Chemical & Energy:
- Acid Fume Scrubbers: Duplex 2205 mesh (1.5 mm thickness) in chemical plant venting.
- Oil Rig Walkways: 316 stainless mesh (6 mm strands) with anti-slip profiles (OSHA 1910.23).
- Architecture & Infrastructure:
- Solar Shading Systems: Powder-coated 304 mesh (40% open area) for LEED-certified buildings.
- Bridge Drainage Grates: Heavy-duty 316 mesh (4 mm thickness) in coastal infrastructure.
- Mining & Manufacturing:
- Vibrating Screens: 310 stainless mesh (10 mm apertures) for high-temperature aggregate screening.
- Machine Safety Guards: 304 mesh (2 mm strands) with ISO 14120 compliance.
