SHEARING

Grating Pacific has fabrication capacity and will gladly shear perforated and expanded metals to specification.  When shearing expanded metals, close attention should be paid to bond and margin requirements.  Pieces can be "Bond Sheared" or "Random Sheared" subject to manufacturing tolerances.

Bond shearing produces pieces with equal, closed diamond configurations on all four sides.  Random shearing produces pieces pieces with partial diamonds on up to all four sides.  Random sheared pieces often have sharp exposed partial strands which should be protected by "U" edging or finish framing.
BOND SHEAR RANDOM SHEAR

 


EXAMPLE A EXAMPLE B
Bond sheared all four sides Bond sheared one side, one end, random sheared one side, one end
EXAMPLE C EXAMPLE D
Bond sheared two sides (SWD), 
random sheared two ends (LWD)
Random sheared all sides and ends

 

 U-EDGING ACCESSORIES
When finish framing of expanded or perforated metals is desired, U-Edging is a popular option.  Manufactured from 18 gauge carbon steel in 20'-0" lengths, U-Edging is available 1" wide with openings that accommodate various sheet thicknesses.  Aluminum and stainless steel U-Edging is available on special order.

 

 HOW TO SPECIFY / ORDER
  MATERIAL: Indicate type of material desired (carbon steel, stainless steel, or aluminum).
 

  STYLE NUMBER:  Indicate style number (such as 3/4" - #9R) which will indicate the desired diamond size and sheet thickness.

 

  SURFACE:  Confirm desired surface, regular or flattened sheet.

 

  QUANTITY & SIZE:  Indicate quantity desired and piece sizes including SWD and LWD.  Provide material list for cut-to-size pieces and sketches for irregular shapes.  For sheared to size orders, review shearing options illustrated above.

 

  FINISHING:  Specify any special finish requirements (galvanizing, paint or anodizing).
