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.
