Technical Info of Perforated Metal


Specifications :
hole pattern ,open area ,strength

Capabilities :
hole size vs thickness

Materials :
Aluminum ,Carbon Steel ,Coated Steel ,Copper and brass ,Inconel and Monel ,Plastic ,Stainless Steel ,Titanium

Tolerances :
Length and Width ,Squareness ,Openings ,Bars ,Flatness ,Camber ,Thickness ,Margins ,Shearing & Slitting ,Blank areas & Locator holes ,Coil Diameter, Length ,Surface finish & Cleanliness  

Calculation of 1 Sq.M. weight:
ps = absolute (specific) weight (Kg) , v/p = open area (%) , s = thickness mm , kg = [s*ps*(100-v/p)]/100

Open area calculation when holes 60° staggered:
V/p = open area (%) ,D = holes diameter (mm) ,P = holes pitch (mm) ,v/p = (D2*90,7)/p2 S = Thickness in mm   D = Wire Diameter in mm     P = Pitch in mm    V = Open Area % Some patterns as following:
