Tolerance Guidelines: Plate / Sheet
Material tolerances not listed below shall be in accordance with the ASTM, ASME, or AMS specification to which the material was produced and certified.
Shearing
.
Standard plate and sheet width and length tolerance is +/-1/16".
.
Upon request, special processing for sheared sheet can be done with width and length tolerance of +1/16", -0.
Precision shearing to +/-0.015" is also available upon request.
.
Sheared expanded metal width and length tolerance is +/-1/8".
.
Diagonal tolerance is 3/16" maximum on sheared items.
Abrasive Saw Cutting
.
Standard abrasive saw cut plate and sheet width and length tolerance is +1/8",-0".
.
Abrasive sawed plate may be furnished with up to (2) mill edges.
.
Diagonal tolerance is 3/16" maximum on saw cut items.
Coil Leveling
.
Tolerance on lengths from the coil line up to 72" long is +1/16", -0. Lengths beyond 72" are +1/8", -0.
.
Diagonal tolerance on the sheet coil leveling line is 1/2" maximum.
Plasma
.
Standard plasma cutting tolerances that apply to both the top and bottom surfaces are as follows:
.
Up to 5/8" thick: +1/8", -0
.
>5/8" to 1-3/4" thick: +1/4", -0
.
Over 1-3/4" thick: +3/8", -0
If you require tighter tolerances, please contact us.
.
Diagonal tolerance is 3/16" maximum on plasma cut items.
