3.2. Member Straightness Tolerances American Institute

As stated in AWS D1.1 Clause 5.23.12:[The tolerance on] Twist of box membersshall be individually determined and mutually agreed upon by the contractor and the owner with proper regard for erection requirements. In the absence of a specified tolerance, an attempt is sometimes made to apply the provisions of ASTM A500 or ASTM A6/A6M. Flatness GD&T BasicsFlatness is the 3D version of surface straightness Instead of the tolerance zone between two lines; the tolerance zone exists between two planes. When Used:When you want to constrain the amount of waviness or variation in a surface without tightening the dimensional tolerance of said surface.

Flatness - Engineering Essentials

Flatness Control:Perfect flatness is when all points of a surface lie in the same plane. Flatness is a form control. The flatness control (c) defines how much a surface on a real part may vary from the ideal flat plane. Tolerance Zone:The flatness tolerance zone is the volume between two parallel planes. Flatness Tolerance eMachineShopFlatness is usually used on a surface associated with a size dimension, acting as a refinement to the size requirement to ensure proper function of a part, or to promote even wear. Flatness tolerance applies in all drawing views, not just the view showing the tolerance callout. An example of flatness How important is sheet and plate steel flatness?Similarly, width flatness was the deviation measured across the rolling direction, again eed in inches per foot. Overall grade flatness was an amalgam of these numbers. Length flatness showed the most marked improvement using TP-CTL (see Figure 4). With TP-CTL, flatness was improved 1.5 times in C1010 and 5.5 times in grade 80 material.

O Page 4 Speedy Metals Information for HR Structural Shapes (HR These shapes conform to ASTM A36 in its manufacture and mechanical tolerances. HR angle is measured by its legs dimension on the exterior and by its thickness. HR angle may be equal or unequal dimension (ie:2 x 2 x 1/4" hr angle / 3 x 2 x 1/4" hr angle). Speedy Metals Information for Hot Rolled Carbon Steel PlateTolerance under specified thickness .010" x 3/4 x 52" wide plate, for example, would have a tolerance range of .740-.780" Because of tolerances, ie thickness, flatness and camber, as well as the hot roll condition, ASTM A36 generally does not finish to specified thickness.

Tolerances for A36 flat bar & Grinding Q'sJan 12, 2007 · If you don't care about final flatness just go for it. You can get the thing real parallel without being flat. As for mill straightness, it may be in tolerance, but is unusually bent. Most A36 that I've used was straight to .005/foot. But I have recieved some that was so crooked it wouldn't work in a automatic band saw.

Read More steelwise - AISC12. These historically developed standard tolerances define the acceptable limits of variation from theoretical dimension for the cross-sectional area, flatness, straightness, camber and sweep for rolled sections. It should be noted that cross-sectional tolerances are eed as a percentage of weight or area, not as tolerances
