Founded in 1998, Anping County Boli Hardware Wiremesh Products Factory has been a trusted manufacturer of industrial wire mesh solutions for over two decades. Our Duplex Stainless Steel Screen, 20 Mesh, 0.84mm Opening, 304 Frame, 500mm x 500mm Panel represents the perfect balance of strength, corrosion resistance, and precision filtration. Designed for demanding environments, this screen panel is engineered to deliver consistent performance across multiple industries, from chemical processing to food production.

Each panel is constructed with a premium duplex stainless steel mesh (typically 2205 or equivalent) that offers superior mechanical strength and resistance to stress corrosion cracking compared to standard 304 or 316 grades. The 304 stainless steel frame provides rigid support and easy installation, ensuring the mesh remains flat and tensioned during operation. With a 20 mesh count and 0.84mm opening, this screen is ideal for separating particles in the range of 0.5mm to 1.0mm, offering high throughput while maintaining accurate cut points.

At Boli Wiremesh, we combine decades of weaving expertise with strict quality control. Our factory is equipped with modern looms and inspection equipment, allowing us to produce screens with uniform mesh openings and precise tolerances. The 500mm x 500mm panel size is a standard popular choice for vibratory sieves, filter presses, and laboratory test sieves, but we also offer custom dimensions to fit your specific equipment. Every panel is visually inspected and tested for dimensional accuracy before shipment.

Key Product Features

Duplex Stainless Steel Mesh: Offers twice the yield strength of 304/316, with excellent resistance to pitting and crevice corrosion in chloride environments.
304 Frame: Provides a robust perimeter that maintains mesh tension and prevents warping under load.
20 Mesh / 0.84mm Opening: Ideal for medium-fine filtration, sifting, and classification tasks.
500mm x 500mm Panel: Standard size fits many industrial sieves and separation equipment; custom sizes available on request.
Plain Weave Construction: Ensures stable mesh geometry and long service life under repeated vibration or pressure.
Edge Finish Options: Plain edges, folded edges, or welded hooks for easy installation depending on application.
High Temperature Resistance: Duplex stainless steel can withstand continuous operating temperatures up to 600°F (316°C) in many environments.

Technical Specifications

Mesh Count	20 wires per inch (20 Mesh)
Opening Size	0.84 mm (840 microns)
Wire Diameter	Approx. 0.42 mm (typical for 20 mesh)
Open Area	Approximately 44% (calculated)
Panel Size	500 mm x 500 mm (19.7" x 19.7")
Frame Thickness	1.5 mm – 3.0 mm (customizable)
Weight (approx.)	0.8 – 1.2 kg per panel (depending on frame thickness)
Applicable Standards	ASTM E11, ISO 3310-1 (optional certification available upon request)

Advantages for Your Business

Extended Service Life: Duplex stainless steel's high strength and corrosion resistance reduce replacement frequency, lowering total cost of ownership.
Accurate Particle Separation: Consistent 0.84mm opening ensures reliable cut points in quality control, mining, and chemical processing.
Easy Integration: 500mm x 500mm standard size fits most industry vibratory sieves and filter frames; can be used as a direct replacement.
Reduced Downtime: Robust construction withstands heavy use and vibration without deformation, minimizing maintenance intervals.
Customizable Options: We can adjust mesh count, wire diameter, frame material, and edge finish to match your specific application requirements.
Cost-Effective: Compared to monel or hastelloy screens, duplex stainless steel offers a good balance of performance and price.

Frequently Asked Questions

Q: What is the difference between duplex stainless steel and standard 304 stainless steel for screens?
A: Duplex stainless steel (e.g., 2205) has a mixed austenitic-ferritic microstructure, offering roughly twice the yield strength of 304 and superior resistance to stress corrosion cracking, pitting, and crevice corrosion. This makes it ideal for harsh environments like seawater, chemical processing, and high-chloride applications.
Q: Can I use this 20 mesh screen for liquid filtration?
A: Yes, it is suitable for coarse liquid filtration where particles larger than 0.84mm need to be removed. However, for finer filtration, a higher mesh count would be recommended. The 304 frame is resistant to many liquids, but for highly corrosive fluids, please consult our technical team.
Q: Is the 500mm x 500mm panel size exact or can it be cut to a different size?
A: The standard panel is manufactured to 500mm x 500mm (±1mm tolerance). We also offer custom sizes; please provide your required dimensions and we can produce accordingly.
Q: What edge finishing options are available?
A: We offer plain edges (no frame), folded edges (with a 304 frame as in this product), or welded hooks for easy installation on vibratory screens. The frame can also be made with a clamping flange custom to your equipment.
Q: How do I clean this screen panel?
A: For most applications, rinsing with water or mild detergent is sufficient. Avoid abrasive brushes that could damage the mesh. For clogged openings, ultrasonic cleaning or compressed air from the reverse side can be effective.
Q: Do you provide certificates of material or test reports?
A: Yes, we can provide mill test certificates for the duplex stainless steel mesh and 304 frame material upon request. Dimensional inspection reports are also available for an additional charge.
Q: What is the typical lead time for this product?
A: For standard 500mm x 500mm panels in stock, we can ship within 3-5 working days. Custom orders typically require 7-15 working days depending on quantity and specifications.
Q: Can you produce this screen with a different mesh count or opening?
A: Absolutely. Our factory can manufacture screens from 1 mesh to 400 mesh and with various opening sizes. Just let us know your requirements, and we will recommend the appropriate wire diameter and material.
