1) These bars are all sheared with a tolerance of +100 mm - 100 mm.Thus
the maximum length we can supply would be 5750 mm in a 20ft container or
11700 mm in a 40ft container.
Because of the shearing operation at least 100 -200 mm of each end of the
bars are not in tolerance and must be cut off before you start to cut your
actual necessary lengths.This is because the shear knives tend to squeeze
the profile during the shearing operation.
2) The profiles supplied in long lengths have straightness tolerances of
1mm / m for mast rails and 1.5 mm/m for carriage bars.
They also have twist tolerances of m for mast rails and carriage bars.
These tolerances are guaranteed for the long lengths.
