Perforated Metal comes in a selection of hole shapes, sizes, gauges and material types, used in a variety of applications like screens, guards, panels, partitions and enclosures
Perforated Metal can take many shapes with numerous choices of perforations. The perforating process is perfectly adaptable to provide surprisingly satisfying design solutions, enhancing the look as well as the performance. Perforated components make products work better with holes that function several ways. Perforated metal parts work more efficiently because the perforating process is so adaptable to the designer’s requirements for perforations and their placement, material specifications and the shape of the finished part.

PRODUCT DEFINITIONS, TERMS AND SPEC INFORMATION:
Important Terms for Perforated Metal:
Spacing for large perforations will be designated be either Centers of perforations, or by the Open Area required. Spacing for small perforations will be designated by either Centers, or Open Area, or if more practical, by the Number of Perforations to the Square Inch.
Pattern of Perforations
Flatness of Sheets & Plates
In the majority of requirements, perforated sheets or plates can be furnished to AISI flatness tolerances. Before ordering any of the following special requirements, discuss then with our sales department:
Guidelines for Minimum Hole Size/Minimum Bar Width
The rule of thumb for perforating is that the hole diameter should not be less than the thickness of the material. The closer to a 1-to-1 ratio, the higher the probability of tool failure and the greater the precautions necessary to avoid it. Modifications can be made in certain instances at additional costs. For stainless steels and similar higher strength materials, it is preferable to specify at least three thickness gauges thinner than hole diameter.
The same general rule applies to bar width. The bar width should be greater than material thickness because of the increased number of punches and therefore, increased perforation tonnage. The bar width can be adjusted at increased costs.
