Perforated media
Hole patterns to specification.
Perforated plate for screen decks, centrifuge baskets and façades. Pattern and thickness matched to the application. As sheet or finished component.
Perforated plate is used for screening, separation and structural support. Hole shape, pitch and arrangement determine the geometric open area. Round, square, rectangular and slotted holes are available in straight or staggered patterns; throughput and strength depend on the plate and the process conditions.
Averinox produces and supplies perforated plate as sheets or finished components, cut, bent, rolled, welded and assembled. Applications include centrifuge baskets, screen decks, drum sections, guards and support plates behind finer mesh.
For architectural applications, IndustryMeetsDesign® supplies perforated and expanded plate for stairs, balustrades, ceilings and façade panels. Colours, patterns and printed images are available on request.
Applications
- Screen decks and sizing plates in quarries and recycling
- Centrifuge baskets and basket retrofits
- Support plates behind fine woven or sintered media
- Sound-damping and ventilation panels
- Architectural façades, ceilings, stairs and balustrades
Features & benefits
- All standard patterns with documented open-area formulas
- Component supply: one supplier from plate to welded assembly
- Materials from mild steel to special alloys
- Decorative programme with coating and print options
- Combined solutions: perforated plate reinforced with mesh overlays
Specifications
spec.json ↗| Property | Value |
|---|---|
| Round (60°/90°/45° staggered), square, rectangular and slotted | |
| From ~0.5 mm up to large structural openings | |
| 0.5 – 10 mm, pattern-dependent | |
| Calculated per pattern, e.g. round 60°: s = 0.906·(d/a)² | |
| Cutting, bending, rolling, welding, punching; complete components | |
| Mill, brushed, electropolished, powder-coated or printed (decorative) |
Materials & variants
Mild and galvanised steel for structural work; 304/316L where corrosion or hygiene demands it; aluminium for weight-critical and architectural use. Special alloys on project basis. Patterns and plate are selected together, since hole size, pitch and thickness limit each other.
Specific applications
Frequently asked questions
How do I specify a perforated plate correctly?
Give us hole shape and size, pitch and pattern angle, plate thickness, material and the margins (unperforated borders). If you only know the process duty, send that instead; we calculate open area and strength for you.
Can you match an existing worn plate?
Yes. Send a sample or a photo with key measurements. We reconstruct the hole pattern and assess whether a different margin layout could improve service life.
What open area do 3 mm holes on a 5 mm pitch give?
For round holes in a 60° staggered pattern, s = 0.906·(d/a)². With 3 mm holes on a 5 mm pitch, this gives 0.906 × (3/5)² ≈ 33% geometric open area. Throughput and strength still need to be checked for the application.
How small can holes be relative to plate thickness?
For punching, the working rule is hole diameter ≥ plate thickness; below that, tooling wear and burrs take over. If the process really needs finer openings than the plate allows, a woven or sintered layer on a coarser perforated support is usually the economical answer.
Do you supply complete centrifuge baskets or only plate?
Both. We supply plate cut, rolled, welded and assembled into complete components. Centrifuge baskets and basket retrofits are part of the range. Send the machine type and basket drawing, or the worn basket, so we can assess and quote the component.
