Our Woven Wire Screens are available in the following weave types:

Plain Weave

This is the most common weave and should only be used when your aperture to wire ratio is 5 or less. There is a single crimp per aperture.

Lock Crimp

Also known as Stronglock, this is a modified plain weave with additional mini-crimps either side of the main crimp.

Flat Top

This weave is characterised by a smooth flat screening surface with less frictional wear. Flat top needs to be specified as this is not a standard weave but is available for almost all apertures. Longer life can be expected from Flat Top Weave.

Intermediate Crimp

Intermediate Crimp the wires are interwoven with three or five crimps per aperture. This weave is used when the aperture to wire ratio is in excess of 5.


Slotted is used when your product being screened is flaky , slot direction can either be with flow or across flow. The number of shutes (binding wires) used will be pre-determined by your aperture verse wire unless otherwise specified.


Harp screens are traditionally used for non-blinding and pegging when you have moisture in your product or near size product that is carrot or cylindrical in shape. Available in Plain/Serpa Harp or Tri Harp.

High Flow Non-Pegging / Blinding Screens

High Flow

These screens are exclusive to Allied Mesh. Hi flow screens are manufactured much the same as Harp Screens however have no blinding wires but rather Polyurethane strips. This makes the screen more flexible and lively which increases the Non-Blinding and Pegging characteristics. We advise this screen be used on the middle and bottom decks where your aperture is relatively small. These screens have a discharge lip manufactured from rubber to prevent fines from escaping where the screens join one another. An overlap is also advised . For manufacturing purposes we will need to know the spacing of your camber/support bars as per the below picture.

Allied Mesh and Filters manufactures and keeps stock of the following very important screen accessories.

Nosing/Capping rubber

Nosing rubber is essential for life expectancy of your screens, if your camber/support bars do not have nosing rubber, you will have metal on metal which will lead to premature failure of your screens. Allied nosing rubber is available in 2 sizes, long and short.

Tensioning Bolt Assembly

Our complete tensioning bolt assembly is specifically designed to improve the life of your screens by ensuring the tension on your screens is kept constant at all times. Our female washer also ensures the side plate of your screen is not damaged by over tightening of the nut with a conventional tensioning bolt.

Individual Parts

Our tensioning bolt is also available as individual parts to accommodate your specific needs or solutions.

2 Bend Clamping Plates

2 Bend clamping plates are the most common and can be supplied with no holes or square cut holes to suite your tensioning bolts. If required we can send you a drawing for completion. Available in 915, 1220 and 1525 long.

3 Bend Clamping Plates

3 Bend clamping plates are not as common as 2 bend and are also available with or without square cut holes in 915, 1220 and 1525 long.

Double Fold Metal Edge

Double Fold Metal Edge is used for wire diameters of 0.70mm down to a 75mesh. Double fold metal edge with canvas is used on 80mesh and greater. Canvas prevents the fine mesh from tearing away from the hook.
