Sheet can be delivered in thickness between 0.3 and 25mm

The available widths of perforated coils go from55 mmto1500 mm, with a maximum weight of approx. 8000kilos. Thickness range from 0.3-3.0mm

The most common width and length of the perforated sheets are as following


Carbon steel (mild steel) Q235A/ Q235B /43A/ A283C/ A36 / S235JR   

·carbon steel cold rolled. It has a quite bright surface. It is used in thickness from 0.3 to3.0 mm

·carbon steel hot rolled pickled or black. The former has an opaque surface and the second has a quite black surface. They are used for the thickness from1.5mmand above.

Pre-galvanized steel

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 punched into the holes so that there is some protection at these points for indoor use.

Electro galvanized steel

This is carbon steel that has passed through an electrolytic bath of zinc which deposits a zinc coating onto the surface.

Pre-painted steel

This is usually pre-galvanized or electro galvanized steel that has been painted. A wide range of different bright or opaque colors is available. Usually the upper surface is protected by a polyethylene film.

Stainless steel 201 304304L316316L321 430

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(AISI316L) and EN 1.4016(AISI 430)(chromatic steel). EN 1.4301(AISI 304) is resistant to corrosion from humidity, and EN 1.4404(AISI316L) 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 is characterized by an excellent resistance to corrosion, form the most oxidant acids to saline atmospheres.
