Welcome to Anping County Boli Hardware Wiremesh Products Factory, a trusted manufacturer since 1998 with an annual export value of US$5 million to US$10 million. Our Alloy Welded Well Screen 304 Stainless Steel 0.2mm Slot for Dewatering Systems is engineered to deliver exceptional performance in groundwater control, mine dewatering, and civil engineering projects. Combining precision slotting with robust welded construction, this screen ensures reliable filtration, high flow rates, and long service life even in harsh environments.
Our factory, located in Hengshui, Hebei, China, has been dedicated to wire mesh manufacturing for over two decades. We serve clients across North America, South America, Europe, Southeast Asia, Africa, and Oceania, providing customized solutions for dewatering systems. The 304 stainless steel material offers excellent corrosion resistance against acidic groundwater and saline conditions, making it ideal for long-term underground installations.
The 0.2mm slot width is specifically designed to balance sand retention and water inflow, preventing clogging while maximizing dewatering efficiency. Each screen is manufactured using advanced welding technology to ensure uniform slot openings and consistent structural strength. Below, we present the key technical specifications and benefits of this product.
Key Features & Technical Specifications
- Material: High-quality 304 stainless steel, providing excellent durability and resistance to rust, corrosion, and chemical attack.

Frequently Asked Questions (FAQ)
-
Q: What is the typical open area of this 0.2mm slot screen?
A: The open area depends on the chosen wire diameter. For a wire diameter of 2.0mm, the open area is approximately 40%. For 3.0mm wire, it is around 30%. We can calculate the exact value for your specific configuration. -
Q: Can the screen be used for both water wells and dewatering?
A: Yes, this screen is designed for dewatering systems, but it is also suitable for water wells, monitoring wells, and other filtration applications where fine sand retention is required. -
Q: What type of connection is available?
A: We offer threaded ends (male/female), plain ends for welding, or flanged connections based on your project requirements. Please specify when ordering. -
Q: Is the screen resistant to corrosion in saline groundwater?
A: 304 stainless steel provides good resistance to mild saline conditions. For highly aggressive environments, we recommend 316 stainless steel as an alternative (available upon request). -
