In accordance with the standards on the execution of steel and aluminum structures, we certify thermal cutting procedures (CPQR). The latter are used by manufacturers to prove the quality of cut surfaces or edges. Cutting shall be carried out in a way that ensures the fulfillment of requirements for geometrical tolerances, perpendicularity, and angularity, and maximum hardness and smoothness of free edges as specified in the European standards.
