As the experts in perforated metal sheets, architectural screens and light metal fabrications in Perth, our team at Perfmet are able to apply different treatments and finishes to your selected product. We are able to arrange a treatment that is tailored to your specifications to give your product the appearance you’re looking for.

The following additional finishing processes are available for our customers:


For some applications a high level of flatness of the sheet is required.


A perforated sheet may be cut to a specific size or shape, meeting the needs of the final application. There are various means of cutting available (e.g. laser, flame, shears etc.)


This type of finishing is necessary to obtain areas without material or to prepare the sheet for bending of the edges.


This work is necessary to obtain products with a concave or convex shape and requires special tooling. This process can furthermore give the sheet more resistance and extra rigidity.


This process is used to give the sheet a cylindrical form.


Our welding process consists of joining two or more parts of different products. It can be carried out in different ways.

Surface Treatment

Surface treatment is principally needed for two reasons: to protect or to decorate the final product. A very wide range of possibilities are available according to the type of material that is used.


Grinding is principally carried out on stainless steel (2B) and aluminium. It can be processed to different finishes.


Degreasing is possible on all kinds of materials and is above all used when further finishing processes like painting or welding are requested.


This process is necessary to achieve a shiny effect of the treated surface and is generally carried out on stainless steel.

Protection Film Application

The application of protective film may be necessary to protect the material from scratches, spots or marks during perforation or transportation.

Hot Dip Galvanising

This kind of finishing is used extensively to obtain good protection against atmospheric agents and therefore against oxidation. The finished product is immerged into a hot liquid zinc bath for full protection.


A deburring process is very useful as it helps reduce sharp edges on perforated sheets. This is necessary for particular applications where a burr may cause a problem or compromise the correct function or look of the final product.

Powder Coating

A range of colours and manufacturers warranties available subject to material and application.


Anodising is principally used on aluminium and is available in various colours.
