Introduction: As a leading manufacturer with over 25 years of experience (since 1998), Anping County Boli Hardware Wiremesh Products Factory is proud to present our premium Wedge Wire Screen Element for sand and gravel filtration. Crafted from high-grade 316L stainless steel with a precise 0.8mm slot opening, this product is engineered to deliver exceptional performance in demanding filtration environments. Our anti-clogging design ensures continuous operation with minimal maintenance, making it an ideal choice for groundwater treatment, dewatering screens, and industrial sand separation. With annual export values exceeding US$5 million and shipments to over 20 countries, our wedge wire screens have earned trust worldwide.
Product Overview: The wedge wire screen element consists of a series of V-shaped stainless steel wires wound around support rods, creating a continuous slot that provides superior mechanical strength and hydraulic efficiency. The 0.8mm slot width is specifically optimized for capturing fine sand and gravel particles while allowing high flow rates. The 316L material offers excellent corrosion resistance in aggressive water conditions, including chlorinated or acidic environments. Our anti-clogging design features a tapered slot profile that prevents particles from becoming lodged, ensuring long service life and reduced downtime.
Key Features and Benefits
- Precision 0.8mm Slot: Uniform slot opening ensures consistent particle retention (sand grains down to 0.8mm) while minimizing pressure drop.
- 316L Stainless Steel Construction: Superior resistance to rust, pitting, and chemical attack – ideal for brackish water, seawater, and industrial effluents.
- Anti-Clogging V-Shaped Profile: The wedge wire geometry creates a self-cleaning effect; particles that pass through the slot are expelled, reducing blinding.
- High Structural Strength: Support rods and continuous winding provide rigidity to withstand high backwash pressures and mechanical loads.
- Customizable Dimensions: Available in various diameters (50mm–200mm) and lengths (500mm–3000mm) to fit existing filter housings or vessels.
- Flexible Connection Options: Threaded, flanged, or plain end connections allow easy integration into sand filters, gravel pack screens, or dewatering systems.
- Low Maintenance: Smooth surface finish and non-clogging slots reduce cleaning frequency, lowering operational costs.

Frequently Asked Questions
- What is the difference between wedge wire screen and wire mesh screen? Wedge wire screen uses V-shaped wires wound around supports, creating a continuous slot that is stronger and less prone to clogging than woven wire mesh. It offers higher flow capacity and longer service life for sand and gravel filtration.
- Can the 0.8mm slot size be customized to other widths? Yes, we offer custom slot sizes from 0.1mm to 10mm based on your particle size requirements. The 0.8mm is a popular choice for fine sand retention.
- Is the 316L material suitable for seawater applications? Absolutely. 316L stainless steel contains molybdenum, which provides excellent resistance to chloride-induced pitting and crevice corrosion, making it ideal for marine and brackish water environments.
- What connection types are available? We provide threaded (NPT or BSP), flanged (ANSI/DIN), and plain end connections. Custom connections can be fabricated upon request.
- How do I prevent clogging in my wedge wire screen? Our anti-clogging design with a V-shaped slot profile naturally reduces particle lodging. For optimal performance, regular backwashing at recommended flow rates is advised. The screen can also be chemically cleaned if needed.
- What is the typical lead time for an order? For standard sizes, lead time is 15–20 working days. Custom orders may require 25–30 working days depending on complexity. We can expedite urgent orders subject to factory capacity.
- Do you provide samples for testing? Yes, we can supply sample pieces (typically 200mm length) for evaluation. Please contact our sales team to discuss sample availability and shipping costs.
- What is the maximum operating pressure for this screen element? The pressure rating depends on the diameter, length, and support structure. Typically, our screens can withstand up to 10 bar (145 psi) for standard designs. For higher pressure applications, we can reinforce the screen with additional support rods.
