When you order, please keep in mind that punching holes in a material add stresses that can result in distortion of the product. The higher the open area, the more material distortion takes place, especially when the perforated pattern is bordered by margins on all four sides. But these distortions can be removed by our special in house leveling process. 
F. Metal Margins
Margins are the blank area along the edges of the sheet. You should provide the width of each margin on all four sides (measured from the edge of the sheet to the edge of the first hole).
G. Tolerances on thickness, pitch, openings, flatness, and shearing for perforated products. You should specify a specific tolerance ,so we can give you a precise product. Standard tolerance will be made unless you specify.
