2. Why mill tolerances can be problematic?
The mill tolerances for structural wide-flange beam are essentially 1/8 inch by 10 feet in length, although this oversimplifies the ASTM A6 / A6M profile standard. A summary of the basic tolerances can be found on pages 6-15 to 6-21 in the Handbook of Steel Construction, 11th Edition. Tables are provided for hot-rolled, welded and hollow ...

Working with Sheet Metal Tolerances
Tolerances on one surface are much tighter than those across multiple surfaces. When looking at a single surface, most of the features are created using one machine, a laser or punch. Like machining and 3D , this allows us to hold tighter tolerances. Its when we introduce bends to the geometry that things get a little less clear.
