Anping County Boli Hardware Wiremesh Products Factory, a trusted manufacturer since 1998, proudly presents our Duplex Stainless Steel Screen with a precise 1.5mm opening and 30% open area, specifically engineered for demanding chemical processing applications. With over two decades of experience and annual export value exceeding US$5 million, we deliver high-quality, corrosion-resistant screens that ensure efficient filtration, sieving, and separation in aggressive environments. Our screens are crafted from premium duplex stainless steel, offering superior strength and longevity compared to conventional materials.
This screen is designed to withstand high pressure, temperature fluctuations, and corrosive chemicals, making it an ideal choice for chemical plants, petrochemical facilities, and industrial filtration systems. The 1.5mm square opening provides consistent particle size control, while the 30% open area maximizes flow rate without compromising structural integrity. Below, we detail the key features and specifications that set our product apart.
Key Features & Benefits
- Superior Corrosion Resistance: Duplex stainless steel (e.g., 2205, 2507) offers excellent resistance to chloride stress corrosion cracking, pitting, and crevice corrosion, ideal for acidic and caustic media.
- High Mechanical Strength: The dual-phase microstructure provides twice the yield strength of austenitic grades, allowing the screen to handle high-pressure drops and mechanical loads.
- Precise Opening Size: 1.5mm (±0.05mm) opening ensures accurate particle classification and consistent filtration results.
- Optimized Open Area: 30% open area balances high flow capacity with sufficient material strength, reducing clogging and pressure loss.
- Customizable Dimensions: Available in widths from 0.5m to 2.0m and lengths up to 30m per roll; wire diameter can be adjusted to meet specific strength requirements.
- Easy Maintenance: Smooth surface finish and good cleanability reduce downtime and extend service life.
- Long Service Life: Duplex stainless steel’s durability minimizes replacement frequency, lowering total cost of ownership.

Frequently Asked Questions
-
Q: What is the difference between duplex and austenitic stainless steel for this screen?
A: Duplex stainless steel offers higher strength and better resistance to chloride stress corrosion cracking, making it more suitable for harsh chemical environments. Austenitic grades (e.g., 304, 316) have lower strength and may corrode under certain conditions. -
Q: Can the opening size be customized to other values?
A: Yes, we can produce screens with openings from 0.5 mm to 10 mm or more. The 1.5mm opening with 30% open area is a standard configuration; custom sizes are available upon request. -
Q: What is the maximum temperature this screen can withstand?
A: Duplex stainless steel (2205) can typically operate up to 300°C (572°F) in continuous service, depending on the specific environment. For higher temperatures, please consult our technical team. -
Q: Do you provide samples for testing?
A: Yes, we offer sample rolls or cut pieces. Please contact us with your requirements, and we can provide a sample for evaluation. -
Q: How is the screen packaged for export?
A: Each roll is wrapped in moisture-proof paper and plastic film, then packed in woven bags or wooden crates for secure sea freight. We ensure proper protection against corrosion and damage during transit. -
Q: What is the typical lead time for production?
A: For standard specifications, lead time is 15–20 working days after order confirmation. Custom orders may require 25–30 working days, depending on volume and complexity. -
Q: Can you cut the screen into specific shapes or panels?
A: Yes, we can provide cut-to-size sheets, welded panels, or custom-shaped screen elements for your equipment. Please provide a drawing or detailed dimensions. -
Q: Is this screen suitable for food processing?
A: While duplex stainless steel is food-grade safe, our standard product is not specifically certified for food contact. If you require food-grade certification, please inform us in advance.
