Dimensional Tolerances
| Dimensional Tolerances | |||
|---|---|---|---|
| Outside Diameter: | Twist: | Maximum twist per 3 feet of length | |
| Largest outside dimension | Outside tolerance including convexity and concavity | Longest outside dimension | |
| up to 2 1/2" | ±.020" | 2" to 2 1/2"inclusive | .062" |
| over 21/2" to 31/2" inclusive | ±.025" | over 21/2" to 4" inclusive | .075" |
| over 31/2" to 51/2" inclusive | ±.030" | over 4" to 6" inclusive | .087" |
| over 51/2" | ±1% | over 6" to 8" inclusive | 100" |
| 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. | ||

Dimensional Tolerances
| Dimensional Tolerances | |||
|---|---|---|---|
| Outside Diameter: | Twist: | Maximum twist per 3 feet of length | |
| Largest outside dimension | Outside tolerance including convexity and concavity | Longest outside dimension | |
| up to 2 1/2" | ±.020" | 2" to 2 1/2"inclusive | .062" |
| over 21/2" to 31/2" inclusive | ±.025" | over 21/2" to 4" inclusive | .075" |
| over 31/2" to 51/2" inclusive | ±.030" | over 4" to 6" inclusive | .087" |
| over 51/2" | ±1% | over 6" to 8" inclusive | 100" |
| 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. | ||
