Filter panels and framed screens
Flat and curved metal screen panels combine a defined screening surface with its frame, edge restraint and rear supports. Woven mesh, perforated plate, wedge wire and laser-slotted panels are made to the machine opening, working face and replacement method.

Woven, perforated and wedge-wire panel surfaces
What we need to make a panel
A panel specification starts with the machine interface and the duty, then fixes the aperture and open area.
Overall panel and clear opening
Defines frame and active area. Dimension the frame exterior and the exposed window separately, from the same installation datums.
Screen type and opening
Defines separation geometry. State weave and wire diameter, hole pattern or slot width together with the working-face direction.
Frame section and mounting
Controls fit and edge seal. Show the frame section, bolt centres, gasket land and the edge retaining detail.
Support spacing
Limits deflection. Locate each rear bar and state the free span between bearing points.
Pressure, flow and cleaning direction
Guides structural layout. Mark process flow and reverse-cleaning arrows on the same section drawing.
Flatness and surface requirements
Defines inspection and handling. Define the measuring plane for flatness and the surface condition at the gasket contact.
Installed boundaries that control area and replacement
| Boundary | Drawing definition | Contribution | Inspection |
|---|---|---|---|
| Outer frame | Outside size, section and fixing centres | Fit and transfer load to the machine | Diagonals and seating plane |
| Clear window | Exposed width and length or profile | Defines the screened opening | Measure after edge retention |
| Rear supports | Bar width, position and free span | Support the working surface | Contact and alignment |
| Retained edge | Clamp overlap or continuous joint | Hold media and control bypass | Corners, fasteners and seal land |
Construction
How a panel is built and cut
- Unsupported spanIntermediate supports shorten the free span. The screen must not pull away from the edge under load.
- Modular jointsJoints between panels need the same bypass control as the outer frame. Use repeatable locating and sealing details.
- Curved panelsSpecify radius and orientation. Flat blank width differs from installed chord width.
- Replaceable mesh or welded assemblyRemovable clamp bars hold a separately replaceable screen. A permanently joined frame and screen are handled as one replacement assembly. The drawing identifies the retained edge, gasket land and fastening access for the chosen maintenance route.

Read the panel from the frame inward
The outside frame locates the panel in the machine. The clear window defines the exposed screening surface, while backing bars and edge clamps cover part of that surface. A dimensioned front view and rear view identify each boundary and the load path into the machine supports.
For curved screens, show the installed radius, chord, arc direction and the mounting datum. For modular decks, number adjacent panels and detail their meeting edges. The joint repeats the perimeter requirements for locating, restraint and a continuous bypass barrier.
Choose the edge around the maintenance task
A removable clamp system permits replacement of the mesh while retaining the frame. Access to fasteners, clamp overlap and a repeatable seating surface make this operation controlled. Permanently welded or bonded assemblies retain the screen and frame together for removal and replacement as a complete panel.
Match the screening task to the media. Woven mesh, perforated and wedge-wire panels separate particles or retain process material. A knitted-mesh frame for gas mist collection uses droplet coalescence and drainage; its support and drain arrangement are specified within the demister family.
Filter panels and framed screens
Applications
Panels are the separation surface wherever bulk solids or slurries are classified, drained or washed.
Liquid screening
Framed mesh and wedge-wire modules separate process solids.
Pre-screens
Perforated panels protect finer media downstream.
Equipment internals
Modular surfaces reduce the size of each maintenance part.
Trommel and rotary screens
Curved and flat panels in fabricated sections, sized to the drum radius, with reinforcement where the span is long.
Check frame geometry and screen restraint
Squareness, flatness and seating geometry determine panel fit and the continuity of the perimeter seal.
Frame
Measure diagonals, fixing centres, flatness and clear opening.
Attachment
Check edge continuity and mesh slack.
Panel joints
Check overlap, gasket seating and adjacent-module positions.
Clear window and support coverage
Check the exposed window after the media is retained. Record clamp-bar overlap, support-bar positions and continuous seating at the perimeter; these features establish the installed screening area.

Questions before ordering
Can a larger panel use the same mesh?
A larger free span increases deformation and the load at the retained edges. Select mesh, support spacing and frame stiffness together for the new panel size.
How is working area calculated?
Use the clear screened surface, then allow for media open area and obstruction from bars, frames and overlaps. Outside dimensions overstate the working area.
When does a screen panel need intermediate supports?
Span, media stiffness and differential pressure determine the need for supports. Provide the mounting grid and an allowable deflection or approved reference panel.
Which dimensions identify a replacement framed panel?
Record outside length and width, thickness, diagonals, fixing-hole centres, clear window and the seating plane. Add a section through the clamp or welded edge and identify the working face. These measurements describe both machine fit and the screen actually exposed to flow.
How do clamp bars affect working area?
Clamp bars cover a strip of media around the window. Calculate exposed screening area from the installed overlap, then account for openings and any support obstruction. Keep this value separate from the outside frame area.
