Mesh-lined strainer baskets
A mesh-lined strainer basket combines a rigid perforated body with a finer wire mesh filtering layer.

Perforated metal screens
Punched sheets, support tubes and strainer parts with round, square or slotted holes. Hole diameter, pitch, thickness and solid margins balance open area against stiffness.

Construction
Hole, pitch and thickness form one specification
- Round-hole geometryFor round holes on equal 60° staggered pitch: open area = 90.69 × (diameter / pitch)² percent. 3 mm holes on 5 mm pitch give about 32.6%.
- Supporting fine mediaBacking holes leave short unsupported spans beneath mesh. Size them for both drainage and the strength of the finer layer.
- Margins and seamsSolid borders, weld bands and mounting areas reduce whole-part open area. Allow enough solid material for rolling and joining.

| Construction | Application and fit | Confirm first | Find a product |
|---|---|---|---|
| Flat perforated screens | The component remains flat in the installed assembly. | Outline, hole pattern, thickness, margins, flatness and edge. | Filter matching products |
| Perforated support tubes | The component needs a cylindrical structural or drainage wall. | Diameter, length, wall, seam, perforation and pressure direction. | Filter matching products |
| Perforated baskets | The screen must collect solids in a removable body. | Seat, body geometry, hole pattern, bottom, handle and clearance. | Filter matching products |
| Framed perforated panels | A larger perforated screen requires a defined frame or supports. | Panel, frame, clear opening, fixing points, pattern and load. | Filter matching products |
Perforated metal screens
Applications
Perforated metal acts as coarse screen or structural backing.
Filter cores
Inner supports and protective sleeves beneath finer media.
Strainer baskets
Rigid walls with or without mesh liners.
Screen panels
Coarse screens with mounting margins and repeatable hole patterns.
Check the pattern and finished shape
Perforation and forming need separate dimensional checks.
01HolesCheck diameter, pitch and stagger direction.
02EdgesInspect burr direction and unperforated margins.
03After formingMeasure flatness, roundness and seam position.

Questions before ordering
Is higher open area always better?
No. Larger or more numerous holes leave less metal to carry load. Thickness, ligament width, curvature and support spacing determine usable stiffness.
Is open area a filtration rating?
No. It is the percentage of surface occupied by openings. Hole size describes geometry; particle-removal efficiency requires additional information.
Why does sheet thickness matter when choosing hole size?
The thickness-to-opening ratio affects punching or laser feasibility, edge condition and remaining ligament strength. Specify thickness, hole pattern and deburring requirement together.
