Perforated mesh can be used for partition screens customized
We can perform these types of perforation: round, square, oval
(slot), special
and decorative.
The most used perforation method is punching. All standard
perforations of diameters between 0.5 mm and 90 mm are made this
way.
Special perforations that are smaller than 0.5 mm in diameter are
made by chemical processes. Round apertures of diameters that are
smaller than the thickness of material are drilled.
At present, we are able to make apertures and bridges between them
that are smaller than the thickness of the material. This is
possible because of new modern materials from which tools are made
and thermic and chemical treatment of the surface of individual
punches.

| Thickness or Gauge | Thickness of the metal sheets do not change during the perforation.
Normally thickness is expressed in gauge, please see the picture.
However, to avoid possible misunderstanding, we would suggest to
express them in inches or millimeters. |
| Width and Length | The most common width and length are as follows: 1000mmX2000mm 1220mmX2400mm 1250mmX2500mm 1250mmX6000mm 1500mmX3000mm 1500mmX6000mm |
