Note: ** expresses the popular specifications we can do, other specifications can be custom made at request.
offers perforated products in a wide range of materials. The qualities of the most commonly requested materials are described below:
Perforated material can be supplied in coils of different widths and lenghts, as well as in sheets of different sizes.
Sheet can be delivered in thickness between 0.3 and 25mm
The available widths of perforated coils go from 55 mm to 1500 mm, with a maximum weight of approx. 8000kilos. Thickness range from 0.3-3.0mm
Carbon steel (mild steel)
Carbon steel is the most commonly used raw material. Principally there are two types of carbon steel:
·carbon steel cold rolled. It has a quite bright surface. It is used in thickness from 0.3 to 3.0 mm
·carbon steel hot rolled pickled or black. The former has an opaque surface and the second has a quite black surface. They are usd for the thickness from 1.5mm and above.
Pre-galvanized steel galvanised
This is carbon steel that has gone through a hot zinc bath just after rolling. This process gives quite a good protection against oxidation and rust, but it is can only used indoors as the protective layer is interrupted where the holes are punched. However, some of the zinc is punshed into the holes so that there is some protection at these points for the indoor use.
Steel and aluminum
Electro galvanized/ galvanised steel
This is carbon steel that has passed through an electroly bath of zinc which deposits a zinc coating onto the surface.
Pre-painted steel
There is usually pre-galvanised or electro galvanised steel that has been painted. A wide range of different bright or opaque colours is available. Usually the upper surface is protected by a polyethylene film. Principally there are two categories of paint. One for indoor use and the other for outdoor use where atmospheric agents are more aggressive.
Stainless steel
Stainless steel is a general name for different kinds of steel alloyed with nickel and chrome, combined with other elements. The three most common types are EN 1.4301(AISI 304), EN 1.4404(AISI 316L) and EN 1.4016(AISI 430)(chromatic steel). EN 1.4301(AISI 304) is resistant to corrosion from humidity, and EN 1.4404(AISI 316L) is resistant to corrosion from humidity and less aggressive acids. EN 1.4016(AISI 430) is less corrosion resistant than the other two types.
The surface can be finished in different ways. Beside the standard surface (2B), one of the most commonly requested finishes is a ground surface. This kind of treatment entails a brushed finish on the surface of the steel. It is possible to ask for various brushed finishes and even shiny effects such as (BA), these are good for decorative purposes.

Aluminum and its alloys
This material is particularly interesting because of its weight advantages, being only one-third the weight of steel. It is also quite resistant to corrosion even in an untreated condition. The wide range of available alloys extends the application possibilities in high-tech segments.
Titanium
Titanium is characterized by an excellent resistance to corrosion, form the most oxidant acids to saline atmospheres.
Copper
Copper is a very malleable and corrosion resistant material.
Brass
Brass includes a wide range of copper-zinc alloy that are strong, durable, hard, conductive, and resistant to wear and corrosion.
Brass can easily be punched, fabricated and formed.
Plastic
As in all other industrial sectors plastic has been introduced as a material for perforated products.
Other materials
It is possible to perforated other materials, and our technicans are at your disposal for further information and consultation.
