Product Overview
Wedge wire screens are generally made of V-section wires to form slot openings which widen inwardly so that materials tend to pass through the screen. The high open area of wedge wire screen provides excellent permeability properties. Our wedge wire screens can be fabricated with materials that are resistant to corrosion and abrasion, or in combination with polyurethane frame for easy installation while reducing labor intensity and machine downtime. They are suitable for many screening applications in a variety of industries including mining, coal, oil, fertilizer, grain, salt and environmental protection.
Bridge slotted well screens manufactured by OASIS have professional design, beautiful appearance with high quality and reasonable price. The bridge slotted well screens are widely applied in all construction field such as water well drilling, engineering, groundwater, agriculture and municipal water supply.

Common Materials for Wedge Wire Screens
(1)Stainless Steel: Stainless steel is one of the most popular materials for wedge wire screens due to its excellent corrosion resistance, strength, and durability. It is available in various grades (e.g., 304, 316, 316L) to suit different applications, but it is not suitable for extremely high-temperature environments. And the cost can be higher than some alternative materi- als.
(2)Duplex Stainless Steel: Duplex stainless steels offer enhanced corrosion resistance and higher strength compared to austenitic stainless steel. They are often chosen for applica- tions where extreme corrosion resistance is required. But the cost is higher than standard stainless steel and it require specialized welding procedure.
(3)Inconel alloy (e.g. Inconel 600, Inconel 625): Inconel alloys are known for their high-temperature resistance and excellent mechanical properties. They are suitable for applications involving elevated temperatures. (4)Hastelloy (e.g. Hastelloy C-276): Hastelloy alloys are superior resistance to a wide range of corrosive chemi cals that excel in harsh chemical environments. They are commonly used in chemical and petrochemical industries. (5)Nickel Alloys (e.g. Monel 400) Monel alloys exhibit strong resistance to corrosion by acids and alkaline solutions. They are frequently used in marine and chemical processing applica- tions.
