Dimensional Tolerances

Tolerances include allowance for convexity or concavity. For
rectangular sections, the tolerance calculated for the larger flat
dimension shall also apply to the smaller flat dimension. This
tolerance may be increased 50 percent when applied to the
smaller dimension, if the ratio of cross sectional dimension
is between 1.5 and 3, and 100 percent when the ratio exceeds 3.
over 8"112"
Straightness:
Permissable variation shall be 1/8" times the number of feet of total length divided by 5:
.125" x (total length) ÷ 5
Wall Thickness:Squareness of Sides:
Maximum allowable variation±10%Adjacent sides may deviate from 90° by a tolerance of plus or minus 2 degrees maximum.
(wall thickness is to be measured at the center of the flat, exclusive
of the weld area, and not at the corners)
Worner Radii:Flash:
The radius of any outside corner shal not exceed three times
the specified wall thickness
Structural tubing usually is supplied flash-in. The height of the
flash will vary with the wall thickness of the tube.
