Perforated metal is another source for filtration, straining and decoration. It is extremely versatile and lightweight. The most common applications include: screens, diffusers, guards, filters, vents and more.

Materials

The materials which are normally perforated are:
- common steel
- stainless steel
- non-ferrous materials
- others, such as plastic, etc.

Size

The thickness ranges generally from 0.6 up to 20 mm, while the maximum length is normally 1500 mm. If the rewinding as bands is not required the length should not be more than 6000 mm. On request it is also possible to exceed these values. The perforated metals can be supplied in sheets and rolls.

Holes

The most required are round, square, elongated slotted and rectangular. Staggered and straight aligned holes are the most common patterns.

Pitch

The pitch or interaxis corresponds to the lower distance between the centers of two nearby holes. In case there are two different pitches in the same perforation (e.g. in case of elongated holes) it is necessary to define these values before starting the production. On request works in iron, stainless steel, brass, copper etc. are supplied as standard sizes 1000 x 2000 and with sizes required by the customer himself.
