Quality Assurance & Control: Every shift of production will be followed by our QA Dept. with our Quality Assurance & Control.

We check every diameter with tensile strength, torsion, cast and surface quality with standards of GB4357/2009 & EN10270-1 & EN10270-2.

Furthermore, we have all the important data to be printed and labeled in a bar code for quality trace-ability.
