2.Feature

a.Very versatile and functional depending on its shape opening and gauge and sixe

b.Can be strong depending on gauge

c.Can vent, screen and filter a variety of solids

d.Is lightweight but durable

Its openings can be chosen for optical requirements appealing to to variour architectural requirements

Perforated Metal also helps to diffuse light and air. If manufacturing a product that needs to be lighter, for the right product application, use perforated metal --- metal sheet retains a high percentage of it's strength after it's perforated but loses a lot of costly weight.

3.Perforations

a.Round Perforations: Staggered (60 degree pattern) is standard. Variations include 45 degree staggered, and straight line pattern.

b.Square Perforations: Staggered or straight line pattern

c.Slotted Perforations: Side staggered, end staggered, or straight lines. Slotted perforations will be round end slots; specify if square end slots are required.

d.Other Perforations: Available upon request.

4.Spacing of Perforations

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.

5.Pattern of Perforations

a.Staggered 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.

b.Slotted Perforations: The long dimension of the slots can be furnished with either the width or length of the sheet in most cases.

6.Margins

a.Perforated 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.

b.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.

c.Unfinished end pattern is standard in the industry.
