Ⅰ: General properties
Maximum production speed: not less than 18 meters per minute (for non-perforated profiles, excluding cutting);
Bending precision: the maximum profile deviations (dimensions and shape) shall not exceed the tolerances specified in EN 10162 (or equivalent tolerances);
Bending quality: ability to bend the profiles of the specified configuration at the specified maximum steel thickness; cracking of the steel or metal coating is not permitted for all required steel grades, when observing the products under magnification ten times.
