Variations include 45 degree staggered, and straight line pattern.Square Perforations: Staggered or straight line pattern.Slotted Perforations: Side staggered, end staggered, or straight lines. Slotted perforations will be round end slots; specify if square end slots are required.Other Perforations: Available upon request.Spacing of PerforationsSpacing 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 PerforationsStaggered Perforations, both Round & Square: Direction of the stagger will normally be the short dimension of the sheet. Straight row of hole is normally parallel to long dimension of sheet.Slotted Perforations: The long dimension of the slots can be furnished with either the width or length of the sheet in most cases.MarginsPerforated Stock Size Sheets & Plates: The long sides of the sheet will be supplied with minimum margins. The short sides of the sheet will have either minimum margins or no margins.Sheets & Plates Re-sheared after Perforating: Special margins are available to specifications but they must carry a tolerance within the limits of the perforating tool.Unfinished end pattern is standard in the industry.Flatness of Sheets & PlatesIn 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:Perforated sheets with extra wide margins.Blank areas required within the perforated area.Perforated sheets with very large percentage of open area.Heavy gage metal in relation to the size of the perforation.Special alloys.Stretcher leveled sheets.Guidelines for Minimum Hole Size/Minimum Bar WidthThe 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.
