Punching Filter Screen

Parameter Category

Description

Common Range

Example

Hole Diameter

Diameter of the perforations

0.5mm – 100mm (Common: 1mm, 2mm, 5mm, 10mm)

Example: 2mm round hole means each hole has a 2mm diameter

Sheet Thickness

Thickness of the metal sheet

0.3mm – 10mm (Common: 0.5mm, 1mm, 1.5mm, 2mm, 3mm)

Thicker plates offer more strength but are heavier and harder to process

Pitch (Center Distance)

Distance between centers of adjacent holes

Typically 1.5 – 3× the hole diameter

Example: 2mm hole, 3mm pitch

Open Area (Porosity)

Percentage of the total sheet area that is open/perforated

20% – 80%

Higher open area = better airflow or light transmission

Hole Arrangement

Hole layout pattern

Straight (90°), Staggered (60°), Horizontal or Vertical arrangement

Staggered layout offers better strength and aesthetics

Common Hole Shapes

Perforation geometry

Round, Slotted (Oblong), Square, Hexagonal, Diamond, Custom designs

Round holes are the most common

Standard Sheet Size

Dimensions of a full sheet

Common sizes: 1000×2000mm1220×2440mm

1250×2500mm1500×3000mm

Custom sizes or coil supply available on request

Edge Treatment

Whether edges are deburred or rolled

Clean edge, burr edge, rolled edge

Rolled edges used for safety or design requirements

Material Type

Base metal materials

Stainless steel, carbon steel,

aluminum, copper, titanium,

galvanized steel, plastic, etc.

Different materials offer varying levels of corrosion resistance and strength

Application

Suggested Specification

Ventilation / Heat Dissipation

Thin sheets, high open area (e.g., 1mm holes, 60% open area)

Screening / Filtering

Small holes, dense patterns (e.g., 1.5mm staggered holes)

Machine Guarding

Thicker sheets with larger holes (e.g., 10mm holes, 2mm thick)

Architectural Decoration

Custom hole designs, balance between aesthetics and strength

Acoustic Panels

High open area with small round or hexagonal holes
