Tolerances of Cold formed Channel Steel: 
Dimensional and cross-sectional tolerances of cold-formed sections are specified

in EN 10162. Customer-specific tolerances can be agreed on separately. SMC

also offers tolerances with cross-sectional wall thicknesses of >8- ≤12.5 mm.

The standard states that the tolerances in this thickness range are to be agreed on separately. 
Advantages of Cold formed Channel Steel: 
-    the strength to weight ratio is excellent; 
-    metals join easily;
-    efficient shapes are available etc. 
These advantages create challenges that are best solved by a good

understanding of how the metals actually perform in a structure.
