Anping Xinye Metal Wire Mesh Products Co., Ltd. is a manufacturer dedicated to metal wire mesh and filtration products. Our welded stainless steel filter screen with a 1mm opening is designed for efficient solid-liquid separation in industrial filtration, dewatering, and particle classification. Produced in our 5,000-10,000 square meter factory, the screen combines precise opening size, rigid welded construction, and stainless steel corrosion resistance. It offers a practical solution for customers who need a reliable screening medium with long service life and low maintenance.
Key Features and Benefits
- Precise 1mm opening: The screen is manufactured to provide a consistent 1mm opening across the panel, allowing liquids to pass while retaining solid particles larger than 1mm. This stable aperture improves separation accuracy and process consistency.
- Welded wire construction: Every intersection of the stainless steel wires is welded, not just woven. This makes the screen rigid, dimensionally stable, and resistant to deformation under load or vibration.
- Strong corrosion resistance: Made from stainless steel grades such as 304 and 316L, the screen can handle water, chemicals, and many corrosive fluids. 316L offers enhanced resistance for saltwater and acidic environments.
- High flow rate: The 1mm square openings provide a good balance between particle retention and open area. The result is high liquid throughput with less pressure drop across the screen.
- Smooth and easy-to-clean surface: The welded surface can be supplied with pickled, passivated, or polished finishes. A smoother finish reduces particle sticking, making cleaning and backwashing more effective.
- Long service life: Because all joints are fused, there are no loose wires to break or shift. This reduces downtime and replacement frequency, especially in continuous filtration processes.
- Customizable dimensions: We can produce flat panels, cut pieces, discs, cylinders, cones, baskets, and framed screens according to your equipment specifications.

Reliable Performance in Solid-Liquid Separation
The welded stainless steel filter screen is often used as a support mesh, strainer, or conveying screen in separation equipment. With a 1mm opening, it can effectively stop solids larger than 1mm while allowing liquid and smaller particles to pass. This makes it suitable for removing sand, debris, sludge, seeds, pulp, metal fines, and other suspended solids from process water, chemicals, oil, and food products.
One of the main advantages of a welded screen is that the openings stay fixed during operation. Woven mesh can stretch, unravel, or become blocked after repeated use. Welded stainless steel mesh maintains its shape and aperture, giving a more consistent filtration result. Its rigid structure also allows it to be used as a load-bearing support for finer filter cloth, preventing the cloth from tearing under pressure.
The screen is also valued in dewatering and draining applications. Water can pass quickly through the 1mm openings, while solid materials remain on the surface and can be removed by vibration, gravity, or mechanical scraper. In conveyor or centrifugal systems, the screen can be formed into curved or drum shapes. This flexibility makes it a useful component in a wide range of designs.
Industrial Application Areas
- Water treatment and wastewater filtration: removes particles from intake water, process water, and sludge dewatering systems.
- Chemical industry: filters catalyst particles, precipitates, and solid impurities from liquid streams.
- Food and beverage processing: strains juice, syrup, cooking oil, and other liquid products to improve clarity.
- Mining and mineral processing: screens ore slurry and helps separate coarse particles from fine liquid suspensions.
- Pharmaceutical and biotechnology: handles coarse filtration, tablet waste separation, and cleaning processes.
- Agriculture and aquaculture: removes fish waste, plant residues, and feed particles from water circulation systems.
Customization Options
We understand that every filter system has different dimensions and performance requirements. Our production process allows flexible customization of length, width, wire diameter, edge treatment, and shape. You can choose a simple flat screen for a filter press, or a welded cylinder for a drum filter. We can also add a mild steel or stainless steel support frame to keep the screen flat and secure during installation. Samples and prototypes are available before mass production, and our team can work from your drawings or existing samples.
Factory Quality and Support
Anping Xinye Metal Wire Mesh Products Co., Ltd. operates a 5,000-10,000 square meter factory with 51-100 employees.

Our screens are shipped from Tianjin, Qingdao, and Shanghai ports to customers in North America, South America, Europe, Southeast Asia, Africa, and other markets. Because we are a manufacturer, we are able to provide factory-direct pricing and respond quickly to technical questions. We invite you to contact us with your required size, quantity, and application details. Our goal is to supply a welded stainless steel filter screen that performs well, lasts long, and reduces your operating costs.
Frequently Asked Questions
Q: What stainless steel materials are available for the 1mm welded screen?
A: Our standard material is stainless steel 304. We also offer 316L stainless steel for applications requiring better corrosion resistance in saltwater, acidic, or chemical environments. Other alloys can be discussed for special needs.
Q: Can the screen be cut to my exact dimensions?
A: Yes. We can supply flat panels cut to your specified length and width, as well as discs, strips, or custom shapes. Edge folding, spot welding, and frame mounting are also available upon request.
Q: Is this screen suitable for high-pressure filtration equipment?
A: The welded structure provides good rigidity and pressure resistance. The appropriate wire diameter and frame design can be selected according to your equipment pressure and load requirements.
Q: How should I clean the screen after use?
A: Because the surface is smooth and the openings are consistent, the screen is easy to clean by water flushing, backwashing, brushing, or ultrasonic cleaning. A polished or passivated surface makes cleaning even more effective.
Q: Can you provide a sample before I place a large order?
A: Yes, samples are available. Please contact us with your required material, size, and quantity, and we can prepare a sample for your evaluation.
Q: What is the lead time for custom welded filter screens?
A: The lead time depends on the order quantity, size, and complexity. For standard 1mm stainless steel welded mesh panels, we can usually arrange production soon after your confirmation. Please ask our sales team for a specific schedule.
Q: What is the minimum order quantity?
A: Minimum order quantity is flexible and can be discussed based on product type and stock availability. For regular sizes, we can offer a small trial order; for custom parts, we may ask for a reasonable quantity.
Q: Can I use this screen as a support mesh for filter cloth?
A: Yes. The 1mm opening and welded structure make it a strong support mesh for fine filter bags, filter cloth, and filter plates. It prevents fine media from collapsing under pressure while keeping high liquid flow.
