Perforated metal
Encyclopedia
Perforated metal, also known as perforated sheet, stamping plates, or perforated screen, is made through the metal stamping
and sheet metal
manufacturing process. Sheet metal materials include steel
, aluminium
, stainless steel
, bronze
, brass
, titanium
, and so on.
Perforated materials are very versatile. From lightweight decorative elements to load-bearing structural components, perforated metal offers unique opportunities to combine strength, functionality and beauty.
Perforated metal is also an excellent means of achieving sustainable design objectives. Perforated sunshades and sunscreens provide privacy for building occupants without blocking the view. And they offer a comfortable level of natural lighting during daylight hours
while deflecting heat to reduce the load on the HVAC
system. Perforated canopies, façades and cladding can also be used to help control interior climate and save energy.
perforation pattern can provide the highest open area.
Straight Pattern: Perforated holes are aligned in straight rows and columns.
Unfinished Ends: The end perforation pattern is not solid and appears rough and incomplete
at the end of the sheet.
Margins: Area on the side, ends, or inside the perforated sheet without perforations
Safe Side Margins: This type of margin is achieved by perforating the material all the way up
to the edge but not on or over the edge
Perforated Tool/Tooling: Interchangeable die sets: pins/punches, die plate, stripper plate, and punch holder used on the perforating presses to perforate the various perforation patterns
Hole Size: Diameter measurement of the perforation shape; measurement from side to side
Finished Ends: The end perforation pattern is solid and appears uniform or complete at the
end of the sheet
Stamping (metalworking)
Stamping includes a variety of sheet-metal forming manufacturing processes, such as punching using a machine press or stamping press, blanking, embossing, bending, flanging, and coining. This could be a single stage operation where every stroke of the press produce the desired form on the sheet...

Sheet metal
Sheet metal is simply metal formed into thin and flat pieces. It is one of the fundamental forms used in metalworking, and can be cut and bent into a variety of different shapes. Countless everyday objects are constructed of the material...

Steel
Steel is an alloy that consists mostly of iron and has a carbon content between 0.2% and 2.1% by weight, depending on the grade. Carbon is the most common alloying material for iron, but various other alloying elements are used, such as manganese, chromium, vanadium, and tungsten...
