perforated sheet
Perforated Metals are sheets of steel,aluminum,stainless steel or specialty alloys that are punched with round,square or ornamental holes in a uniform pattern.Popular sheet thickness ranges from 26 gauge through 1/4" plate(thicker plates are available on special order). Common hole size range from .020 to 1" and greater.

Round hole perforated sheets are the most common and most requested.There are several types of hole diameters:very small,medium,large size.Hole pattern is of primary importance:the most popular arrangement is the 60 degree angle pattern,which combines a high rigidity and a decent proportion between open and full areas.The 90 degree pattern is equally popular,abouve all for aesthetic needs whereas the 45 degree pattern is now almost disused.
