Compared to the hot-rolled sheet pile, which has got over 100 years of history, the cold-formed sheet pile is a new technology, and it has many advantages. It is a continuous cold-forming process through numerous rollers. The process is not a sudden bending of the material but a step-by-step process. Thus compared to the traditional bending process, it will not damage the material internally.
The production standard is EN10249-1, and the tolerance is based on EN10249-2. Here is a summary of the tolerances:
