Squareness
In addition to achieving a certain length and width tolerance, shearing is used to make a sheet square. Checked for by measuring the distance between diagonally opposing corners, the amount a sheet is out-of-square is determined by taking 1/2 the difference of the measurements. Squareness is achieved by trimming the sides and/or ends.
The following tolerances are achievable for re-squared sheets. For the tightest tolerances possible, specify Legends Superior.
REMINDER: Unless specified, Legends India standard tolerance will be applicable.
