What Is a Wedge Wire Support Screen Plate
A wedge wire support screen plate is a flat or circular structural component manufactured from V-shaped stainless steel profile wires resistance-welded to a grid of support beams. The screen plate is installed inside filter vessels, ion exchange columns, and reactors, where it supports filter media, resin beds, or catalyst particles while allowing fluid to pass through uniformly. The V-shaped slots retain the media while permitting flow, preventing media migration and ensuring efficient operation. The all-welded construction provides high mechanical strength and dimensional stability under load.

The V-shaped slots retain the media while permitting flow, preventing media migration and ensuring efficient operation. The all-welded construction provides high mechanical strength and dimensional stability under load.
Precision Slots for Media Retention
The V-shaped slot geometry ensures effective media retention. The slots are narrow at the top surface and wider below, preventing media particles from becoming wedged. Slot openings range from 0.1 mm to 3.0 mm, with common applications using 0.2 mm to 0.5 mm. The slot opening must be smaller than the minimum media particle size. Slot tolerance is held to ±0.03 mm to ±0.05 mm. The open area typically ranges from 15% to 40%, balancing flow capacity with media retention.
Structural Design for Load Bearing
The support screen plate is constructed with V-shaped profile wires on the top surface and a grid of support beams underneath. The support beams are spaced to provide adequate load capacity for the weight of the media bed and the hydraulic pressure. Profile wire sizes commonly used include 1.5×3 mm, 2×4 mm, and 3×5 mm. The plate can be manufactured as a single piece or in multiple segments for larger vessels.
Applications in Water Treatment and Chemical Processing
Wedge wire support screen plates are used in a range of filtration applications. In water treatment, they support sand and carbon filter media. In ion exchange, they support resin beds. In chemical processing, they support catalyst beds. The plate is also used in pharmaceutical and food processing applications.
Custom Manufacturing and Quality Assurance
Anping County Yan Zhao Mining Sieve Mesh Co., Ltd. has been manufacturing support screen plates for over 20 years. Each plate is custom manufactured to customer specifications. For custom plates, we confirm material grade, slot opening, overall dimensions, and support beam spacing before production. Lead time typically ranges from 7 to 30 days.
