The requirements for the geometric dimensions and quality of the outer coating suggest the possibility of minor damage that does not contribute to the violation of the integrity of the coating. Before purchasing, it is important to familiarize yourself with the tolerances for the main parameters. State standards allow deviations in height in both directions by 1 millimeter. In terms of width, this indicator should not differ from what is prescribed by state standards, and be more or less than the established one by 8 millimeters. The length tolerance is 10 millimeters.
What is important to know before making a purchase?

If you have a sheet that is marked C21-1000, then this indicates that the material is wall, the height of the profile trapezoid is 21 millimeters, and the useful, that is, working, profile width is 1000 millimeters.
Conclusion
It is also worth considering the fact that the final cost will depend on the type of coverage, which is why the price may differ from that indicated by either 10 or 300%.
