Custom Wire Wrapped Screen with Cold Galvanized Surface and V Shaped Wedge Wire Construction for Performance in Water Wells
Product Overview
This custom-manufactured galvanized wedge wire screen—also known as a water well screen, continuous-slot screen, Johnson-type screen, or wire-wound screen—has a cold-galvanized exterior for corrosion resistance. It consists of V-shaped wedge wire securely welded onto longitudinal support ribs to form precise, continuous slots. Welded ring ends are supplied as standard connections. With its all-welded structure, the screen offers high mechanical strength, a large open area, anti-clogging performance, and stable sand control, and is widely used in shallow water wells, vertical wells, and horizontal wells.

FAQ
Q1: What is a cold-galvanized wedge wire screen?
A: A cold-galvanized wedge wire screen, also known as a water well screen, continuous slot screen, Johnson-type screen, or wire wrapped screen, is a custom-manufactured well filter pipe. It is made of V-shaped wedge wire fully welded onto longitudinal support ribs to form precise continuous slots. The exterior is cold galvanized for corrosion protection, and welding ring ends are standard for field connection.
Q2: What are the main benefits of this water well screen?
A: The continuous slot wedge wire design offers self-cleaning performance, low clogging risk, high open area, and high water intake capacity. The fully welded structure provides high mechanical strength and pressure resistance, while the cold-galvanized surface improves corrosion resistance in underground well environments. It also delivers stable sand control for shallow water wells, vertical wells, and horizontal wells.
Q3: What specifications can be customized?
A: Available OD: 25–1500 mm. Slot opening: min. 0.05 mm, customizable. Single length: 0–6 m, with custom length available. End connections include welding rings as standard, with optional plain ends, threaded ends, and flanged ends. OEM and ODM services are supported, and screens can be tailor-made per client drawings and requirements.
Q4: Which material should I choose for different water quality?
A: Available materials include AISI 304, 304L, 316L, Duplex 2205, and 2507. AISI 304/304L is suitable for general water conditions. 316L offers better corrosion resistance in chloride-containing water. Duplex 2205 and 2507 are recommended for high-chloride, seawater, or harsh corrosive environments. The cold-galvanized surface provides additional protection for underground well applications.
Q5: What applications and end connections are supported?
A: This galvanized wedge wire screen is widely used in shallow water wells, vertical wells, horizontal wells, groundwater extraction, well sand control, and water filtration. Welding ring ends make field connection and installation easier. Optional plain ends, threaded ends, and flanged ends are also available for different installation needs.
