Informations of Perforated Metal:

Perforated metals are sheets of metal of various types which have been perforated with holes in various shapes and sizes. The perforating process is typically performed using specialised tooling in high speed punching machines. This creates an attractive and functional product. Typical materials used are steel, stainless steel, pre-galvanised steel, aluminium, brass, copper and metal sheathed composite panels.

Benifit of the Perforated Metal:

Perforated materials have many advantages ranging from weight reduction through acoustic noise reduction to heat dissipation and much much more.,
Weight reduction
Radiation containment
Separation
Heat dissipation
Transparency
Anti-Skid

Acoustic performance helps people or workers to limit health effects from noise. Studies have shown that perforated metals help reduce sound levels.Studies show that having buildings use perforated metal sheets in front of their façade can bring in one study 29% energy savings (HVAC + Lighting estimated consumption in 1 year) and in the second one 45% energy savings ( heating, ventilation, air conditioning). Depending on the location of the building (intensity of the external sun), solar irradiation can be decrease by 77.9%

Perforated metal needs very limited maintenance and cleaning.

This comes with a financial benefit (not having to pay a cleaning service) as long with an environment benefit of not using detergents, energy or water (drinking water from the main) for cleaning.

Perforated metal is long lasting and does not need to be replaced for years. This saves on financial costs. This enables not having to annoy occupiers of the building with work related annoyance like noise or dust. This comes with a big environmental benefit of not creating a new material sheet and its related C02 costs.

Perforated metal can be used in every location, you just need to choose the right alloy for the stainless steelso that it resists to seaside atmosphere or city car polluted atmosphere.

Perforated metal sheets are light which is very advantageous for the building structure when they are installed on the building.
Punching is the way most perforated sheets are created.The metal removed from the sheets are recuperated and recycled to be reused for creating new sheets. Sheets of expanded metal are made in a way that does not remove any metal from the sheet.
The flexibility in the design provides room for creative architectural ideas.

Perforated metal is used in the construction of bioclimatic hybrid façades
