It was a great honor that, prior to attending Cortec's 50th Anniversary Celebration, the Qingdao Cortec team traveled to St Paul to visit Caterpillar, where we conducted an on-site inspection of the anti-corrosion performance of Caterpillar frames that our company had packaged in Xuzhou, China. After being transported by sea, these frames were stored in an outdoor warehouse in St Paul. The on-site inspection results showed that the anti-corrosion performance was satisfactory. We would like to express our heartfelt gratitude to Cortec Headquarters for their strong support, and also to Caterpillar for their long-standing trust in our company.
