As a leading manufacturer from Anping County Boli Hardware Wiremesh Products Factory, established in 1998, we specialize in producing high-quality Q235 Galvanized Circular-Hole Filter Pipe for groundwater dewatering wells. With over two decades of experience and an annual export value exceeding US$5 million, our factory is dedicated to providing durable and efficient filtration solutions that meet the stringent demands of water well projects worldwide. This product is engineered to optimize water flow while preventing sand and sediment ingress, ensuring long-term reliability in dewatering applications.
Our Q235 Galvanized Circular-Hole Filter Pipe is manufactured from premium Q235 carbon steel, with a precise 2mm wall thickness that offers excellent strength and corrosion resistance after hot-dip galvanizing. The circular-hole design is specifically configured to maximize open area for efficient water intake, while the galvanized coating provides robust protection against underground corrosive environments. Whether used in foundation dewatering, municipal water supply, or agricultural irrigation wells, this filter pipe delivers consistent performance.
We understand that every project has unique requirements. Therefore, our filter pipes are available in customizable diameters and lengths, with various slot patterns to match specific soil conditions. The Q235 material ensures cost-effectiveness without compromising mechanical integrity, making it a preferred choice for contractors and engineers.
Key Features & Benefits
- Superior Material Quality: Q235 carbon steel provides high tensile strength and ductility, ideal for deep well installations.
- Hot-Dip Galvanized Coating: Uniform zinc layer (≥60μm) offers excellent corrosion resistance, extending service life in harsh groundwater conditions.
- Circular-Hole Design: Precision-punched holes ensure consistent water flow with minimal clogging, improving dewatering efficiency.
- 2mm Wall Thickness: Balanced between strength and weight, easy to handle and install while withstanding external pressure.
- Customizable Options: Diameter (50mm-600mm), length (1m-6m), hole size (2mm-10mm), and end connections (threaded / welded / plain) available upon request.
- Cost-Effective Solution: Long lifespan reduces replacement frequency, lowering total project costs.
- Wide Application: Suitable for groundwater dewatering wells, monitoring wells, water supply wells, and horizontal drainage systems.

Why Choose Our Q235 Galvanized Circular-Hole Filter Pipe?
Our factory has been manufacturing wire mesh and filter products since 1998, accumulating vast expertise in metal processing and surface treatment. Each pipe undergoes strict quality control to ensure uniform hole spacing, consistent galvanizing thickness, and dimensional accuracy. We serve clients across North America, South America, Europe, Africa, Oceania, and Asia, with a strong reputation for reliability.
The 2mm thickness combined with Q235 material provides a perfect balance: strong enough to withstand ground pressure during installation and operation, yet light enough to reduce transportation and handling costs. The circular holes are arranged in a staggered pattern to maximize open area without compromising structural integrity, allowing for efficient water flow while effectively filtering out fine sand particles.
We offer flexible customization: pipe diameter, length, hole size, and end connections can be tailored to your project specifications. Whether you need a small-diameter monitoring well screen or a large-diameter dewatering well pipe, we can produce it efficiently. Our annual export value of US$5–10 million reflects our ability to handle bulk orders with consistent quality.
Compared to plastic or stainless steel alternatives, our galvanized steel filter pipe provides superior strength at a competitive price. The hot-dip galvanized coating meets international anti-corrosion standards, ensuring decades of service in most groundwater environments. Additionally, the circular-hole design is less prone to clogging than slot-type screens, making it ideal for fine sand formations.
Frequently Asked Questions (FAQ)
-
Q: What is the maximum depth this filter pipe can be used for?
A: The Q235 material with 2mm thickness is suitable for depths up to 150 meters, depending on soil conditions and diameter. For deeper wells, we recommend consulting our engineers for customized reinforcement. -
Q: Can the hole size be customized for different soil types?
A: Yes, we offer hole diameters from 3mm to 10mm. For fine sand, smaller holes (3-5mm) are recommended; for coarse sand, larger holes (6-10mm) work well. We can also produce non-standard sizes upon request. -
Q: How does the galvanized coating perform in corrosive groundwater?
A: Hot-dip galvanizing provides excellent protection against general corrosion. For highly acidic or saline water, we can apply additional coatings or recommend stainless steel grades for enhanced resistance. -
Q: What are the available end connections?
A: We offer threaded ends (NPT, BSP, or custom), plain ends for welding, and flanged connections. Please specify your requirement when ordering. -
Q: Is the pipe suitable for horizontal directional drilling (HDD) installation?
A: Yes, the pipe can be used in HDD applications. We recommend welded connections for continuous runs and can provide custom lengths to minimize joints. -
Q: What is the minimum order quantity (MOQ)?
A: Our standard MOQ is 100 meters for common sizes. For custom specifications, MOQ may vary; please contact us for details. -
Q: How long does delivery take?
A: For standard sizes, production takes 15-20 working days. Custom orders typically require 20-30 working days, depending on complexity. We ship from Tianjin, Qingdao, Shanghai, or Foshan ports. -
Q: Do you provide samples for testing?
A: Yes, we can provide samples (length 300mm) for quality evaluation. Sample cost is negotiable, and shipping is at the buyer's expense. The sample fee will be deducted from the first order.
