Duplex 2205 Stainless Steel Wire Mesh is a high-performance industrial filtration and screening solution engineered for the most demanding environments. By combining the benefits of ferritic and austenitic stainless steels, this duplex structure delivers a superior balance of mechanical strength and exceptional corrosion resistance, significantly outperforming standard 316 stainless steel in aggressive chemical and marine settings.
Designed for longevity and precision, our Duplex 2205 mesh is available in a vast array of weave types and specifications. From micron-level fine filtration to heavy-duty structural reinforcement, it provides unmatched stability under high pressure and extreme flow conditions, making it the gold standard for the oil, gas, and petrochemical industries.

Available in multiple weaves and diameters, ideal for everything from fine filtration to structural safety barriers.
High resistance to deformation under high pressure and flow conditions, ensuring consistent filtration accuracy.
Tailored mesh counts and aperture sizes to meet specific industrial separation and screening requirements.
Optimized for sand control screens and high-pressure filtration in offshore production.
Expert screening solutions for corrosive acids, alkalis, and chloride-heavy solutions.
High-durability mesh for desalination systems and seawater filtration structures.
Premium facades, safety barriers, and railing infills combining strength and aesthetics.
Hygiene-compliant mesh for high-strength processing equipment and filtration.
Precision gas and liquid separation systems requiring high mechanical stability.
| Performance Metric | Standard SS316 Mesh | Duplex 2205 Mesh |
|---|---|---|
| Yield Strength | Baseline | ~2x Higher |
| Chloride Resistance | Moderate | Excellent |
| Pitting Corrosion | Susceptible | Highly Resistant |
| Service Interval | Standard | Extended |
| Long-term Cost | Higher (Replacement) | Lower (Durability) |
Duplex 2205 provides significantly higher yield strength and superior resistance to stress corrosion cracking and pitting, especially in high-chloride environments where SS316 often fails.
We offer Plain weave for general use, Twill weave for higher mesh counts, and Dutch/Twilled Dutch weaves specifically for fine and ultra-fine filtration applications.
Yes, we provide customized aperture sizes ranging from micron-level openings for filtration to several millimeters for coarse screening, depending on your application needs.
For long-term applications, it is generally advised to keep operating temperatures below approximately 300°C to maintain optimal mechanical properties and corrosion resistance.
Absolutely. Due to its high resistance to seawater pitting and crevice corrosion, it is the ideal choice for desalination plants and offshore oil and gas structures.
We supply the mesh in rolls and cut sheets. Additionally, we can provide further fabrication into filter elements, cylinders, and custom screens.
