Perforated metal

  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.

Technical terms

Staggered Pattern: Holes are aligned in staggered or nested orientation. A staggered 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
