Wall Thickness

Wall Thickness Tolerances for Class A Hollow Shapes

Tolerance Wall Thickness

all dimesions in millimetres unless specified - tighter tolerances available on request

Note:  When the dimensions specified are outside and inside, rather than wall thickness itself, the allowable deviation of the wall thickness applies to the mean wall thickness. The mean wall thickness is the average of the maximum and minimum measured wall thickness, when measured at the ends of the cut length.
