Wedge wire screens, panels and cylinders
As a product with numerous specialized applications, we can supply or produce wedge wire products in SS430, SS302, SS304, SS304L, SS316, SS316L materials. These may also be called Johnson screens after the inventor (1904 by Edward E. Johnson who invented the world’s first continuous slot wire wrapped well screen). These are available from 0.01mm (10 Micron) up to 15mm (1500 micron) and with with flanges, end rings or BSP threads. We produce wedge wire products according to specification or drawings.
Generally, wedge wire materials in stock are 430, 304 and 316 stainless steel.
We require as much information as possible for manufacture quotes.
We make Johnson wedge wire screens to 170mm OD in South Africa and smaller diameters with specialist manufacturing associates.

See the above screen cylinder and how it differs from below. The above is generally for a flow from inside to outside, while the below Johnson screen is for the more typical flow from outside to inside.
Due to the many possible wire configurations, the initial specification need to be quite clear.
Mining, as profile wire screens used in mining, recycling and mineral processing
Wedge wire mineral processing and recycling screens have over the years become synonymous throughout the mineral processing, recycling and aggregate industries worldwide, being recognised for its incomparable screening properties for high volume separation and classification, with the ability to cope amongst abrasive materials and heavy duty applications.
You can use a stainless steel sieve screen in mineral processing plants for coal, potash, taconite, sand, gravel etc..
Wedge wire screens are used in the agricultural industry. Among these industrial profile screens are sieve bends, flat panels and cylinders used in screw presses.
- Primary agricultural uses for wedge wire screens:
- Feed recovery
- Manure separation
Wedge Wire Screens for Waste Water and water treatment
Primary wastewater uses for wedge wire screens:
- Solids removal from process wastewater
- Process wastewater/sewage treatment
- Water diversion, keep trash out of rivers, streams, sewers, fountains, etc.
- Fruit and vegetable wastewater processing
Food Processing and beverage applications
Our wedge wire screens are used in various food processing applications as well as for the de-watering of waste water in meat, poultry and vegetable processing industries.
