Anping County Boli Hardware Wiremesh Products Factory has been a trusted manufacturer of industrial screening solutions since 1998. Our Precision Drilled Galvanized Round-Hole Dewatering Well Screen is engineered to deliver reliable performance in demanding water extraction and filtration applications. With slot options ranging from 0.5mm to 2mm and a standard length of 4 meters, this industrial-grade screen offers exceptional durability, precise water flow control, and long service life. Whether you need to dewater a construction site, manage groundwater in mining, or optimize a municipal water well, our product meets the highest standards of precision and strength.
This well screen is manufactured using advanced drilling technology that ensures uniform hole size and consistent slot geometry. The hot-dip galvanized coating provides robust corrosion resistance, making it suitable for both fresh and saline water environments. Each screen is rigorously inspected to maintain slot tolerances and structural integrity. Below we break down the key features, specifications, and benefits to help you make an informed decision.
Key Features
- Precision Drilled Round Holes – Achieved through CNC drilling machines, ensuring uniform slot width and minimal deviation. This guarantees consistent water intake and accurate sand/gravel retention.
- Galvanized Surface Finish – Hot-dip galvanized per ASTM A123 (upon request) provides excellent resistance to rust, corrosion, and chemical attack. Ideal for long-term underground or underwater use.
- Multiple Slot Options – Choose from 0.5mm, 1.0mm, 1.5mm, or 2.0mm slot widths to match your specific formation sand size and dewatering requirements. Custom slot sizes are available upon request.
- Standard 4-Meter Length – Facilitates easy handling, transportation, and installation. Can be cut to custom lengths or joined using couplings (sold separately) for deeper wells.
- Industrial Grade Strength – Manufactured from high-quality galvanized steel sheet with thickness ranging from 1.5mm to 3.0mm (optional). Withstands high static loads and dynamic stress during pumping.
- High Open Area – The round-hole pattern maximizes the screen’s open area, allowing efficient water flow while maintaining structural stability. This reduces head loss and improves well yield.

Advantages & Benefits
- Enhanced Well Efficiency – The precision-drilled round holes minimize clogging and allow fine sand to pass through, reducing pump wear and maintenance frequency.
- Long Service Life – Galvanized coating protects against corrosion even in aggressive groundwater conditions. Tests show durability exceeding 10 years in typical environments.
- Easy Installation – Lightweight yet strong, the 4-meter sections can be handled by a small crew, lowering labor costs. Coupling options enable quick assembly.
- Cost-Effective – Compared to stainless steel screens, our galvanized screen offers excellent performance at a fraction of the price, ideal for large-scale projects.
- Customizable – We can adjust slot width, diameter, length, and wall thickness to meet your project’s unique requirements. Quick turnaround for custom orders.
- Consistent Quality – Each batch undergoes strict QC including slot measurement, tensile testing, and galvanizing thickness check. Our factory has been ISO 9001 certified (optional).

Frequently Asked Questions
-
Q: What is the difference between a round-hole screen and a slot-wire screen for dewatering?
A: Round-hole screens are drilled from solid pipe, providing higher strength and uniform openings. They are best for formations with fine sand or where the screen must withstand high collapse pressure. Slot-wire screens offer higher open area but are less robust. Our round-hole screen is ideal for industrial dewatering wells requiring durability. -
Q: Can I get a sample before placing a bulk order?
A: Yes, we offer sample pieces (e.g., 300mm length) for testing. The sample cost is minimal and can be deducted from your first order. Please contact our sales team for details. -
Q: How do I choose the correct slot size for my well?
A: The slot size should be slightly smaller than the smallest formation sand particle to retain the majority of fines while allowing water to flow. We recommend a sieve analysis of your soil. Our engineers can help you select the optimal slot based on the D50 or D10 particle size. -
Q: Is the galvanized coating safe for drinking water wells?
A: Galvanized steel can be used in non-potable or industrial water wells. For potable water, we recommend using stainless steel or epoxy-coated screens. Please consult with your local regulations. -
Q: What is the maximum depth these screens can be used?
A: The depth depends on the screen diameter and wall thickness. For a 4-inch diameter screen with 2mm wall thickness, typical maximum depth is around 150 meters. For deeper applications, we can increase wall thickness or use higher-grade steel. Contact us for a specific calculation. -
Q: Do you provide couplings or end caps?
A: Yes, we supply compatible couplings, end caps, and reducers made from galvanized steel. They are available in standard sizes and can be ordered together with the screens. -
Q: What is the minimum order quantity (MOQ)?
A: Our MOQ is typically 50 pieces for standard sizes, but we can accommodate smaller trial orders for new customers. For custom specifications, MOQ may be higher. -
Q: How long does shipping take to North America?
A: For sea freight, delivery to major ports in North America usually takes 25-35 days after production (which takes 15-20 days for standard orders). Air freight is available for urgent needs.
