As consumers, we are not apt to wonder much about the work that holesdo for us. But, for a designer or engineer, holes can provide the perfectsolution to many problems. The versatility of perforated materials can bedemonstrated by its use for sound suppression, microwave and radiocontainment, filtration and purification of air, smoke, water, and gases ofevery description.
Perforated materials offer a variety of patterns from the most basic to thedecorative to satisfy your application.
Perforated metals are available in carbon, stainless steel, galvanized,aluminum and special alloys. Perforated Plastic - Constructed ofpolypropylene or PVC is also available for corrosive environments andapplications requiring lower weight.

The Versatility of HolesRound Hole Patterns Round holes rangingfrom under .020 to over 6 account for 80%of the production of the perforating industry.Round holes can be produced with greaterefficiency and less expense than any otherhole shape. The dies and punches to makeround holes are the most cost efficient tobuild and maintain. Round holes are themost versatile in their application, providinga wide range of open areas and attractiveappearance.
60 Staggered Round Hole Pattern Thispattern is the most popular hole arrangementdue to its inherent strength, wide range ofopen areas, and its attractive appearance.
Straight Center Round Hole Pattern Thispattern is also a popular hole arrangementthat is available in avariety of sizes andopen areas. Pleasenote, however, astraight line patternof holes is weakerthan a staggeredpattern and has a tendency to stretch thematerial to a greater degree.
45 Staggered Round Hole Pattern Offersthe sameadvantages as the60 staggeredpattern but with adifferent aestheticappearance.
Square Hole Patterns Square holes are idealfor applications where visibility and through-put are priorities but strength isnt asessential, such as guards and decorativecovers. These patterns provide a higherpercent open area but are lower in strengthcompared to round hole patterns. Squarehole patterns are available with staggeredand straight centers.
Hexagon Hole Pattern Ideal for applicationswhere maximumthrough-put isrequired, providesthe highest openarea of all patternalternatives.
Slots Slots are particularly well suited forsorting and grading of solid objects. Theelongated slot opening increases thethrough-put for this type of application.There are four slot patterns to choose from:
Round End -End Staggered Ideal forsorting and grading solids that flow over thelength dimension of the material.
Round End -Side Staggered Ideal forsorting and grading solids that flow over thewidth dimension of the material.
Round End -Straight Lines Ideal forsorting and grading solids when used in ashaking application.
Square End -Straight Lines Ideal forsorting and grading solids when used in ashaking application.

Design Details
Minimum Hole SizeThe rule of thumb for perforating carbon steel and aluminum is that thehole diameter should not be less than the thickness of the material. Thecloser this 1-to-1 relationship is approached, the higher will be the proba-bility for tool failure, and the greater the precautions necessary to avoid it.For stainless steel and other higher strength materials, it is best to drop atleast one thickness gauge thinner than hole diameter.
Minimum Bar WidthThe material left between perforations is called the bar width. The samerule of thumb of the 1-to-1 relationship to thickness is the limit for barwidth as in hole diameter. Keep the bar width greater than the thicknessof the material to avoid problems. As the 1-to-1 relationship isapproached, the increasing number of punches required sharplyescalates the process tonnage needed to perforate the pattern, thus cre-ating potential for problems.
In some cases, variations to these recommendations can be accommo-dated but with additional production costs.
End PatternsUnfinished- Standard end pattern at the beginning and endof the work piece resulting from the stepped perforating proce-dure pattern.Finished- Requires special tooling or idling of the last row ofpunches to complete the pattern, thus slowing the perforatingprocess and increasing costs. The finished end pattern is notstandard and should be specified if desired.
Side MarginsMargins along the sides of the perforated sheet introducestresses into the sheet and cause distortion, so they should bekept to a minimum width. Excessive or uneven margins canactually cause buckling or a degree of distortion that cant becompletely corrected by roller leveling. Additionally, when holesare small and the percent of open area is high, distortion canbecome exaggerated. The minimum side margin is determinedby the die layout and the width of the material (see table below).
Flow of MaterialIf the sieving process requires aspecified arrangement of holes,the direction of flow must beclearly specified.

Flatness Tolerances
Superior Superior
Flatness tolerance refers to the maximum deviation from a horizontal flat surface measured when the material is placed on a perfectly flattable. A ruler which does not flatten the material will give the degree of flatness. The measurement being from the highest point (orpoints) of the sheet or plate to the table surface minus the material thickness. Two levels of quality are available: Commercial Quality andSuperior Quality. Note: If not otherwise specified, commercial quality is supplied. Flatness tolerances listed are of roller leveledsheets or plates with minimum or no margins. Flatness variation guidelines listed below should be followed.
Length 10 or less: variation should not exceed amount shown belowLength greater than 10: variation for any 10 of length should not exceed the amount shown.Longer dimension less than 36: variation along the length and across the width should not exceed 1/4 in each direction.Longer dimension from 36 to 72: variation should not exceed 75% of the amount shown for the specified width, but never less than 1/4.Note: Margins will usually increase the maximum deviation.
