Our Doctrine: Quality Number One

At Jinan ZenTi Heavy Industry, we always place the greatest emphasis on product quality to ensure that our customers receive the best possible product experience. That’s why we have developed an efficient and integrated risk control system to ensure that all products are of the highest quality and meet all safety standards. We strive to produce only the best products and services, and we keep up-to-date with the latest technological advances to ensure that our products are of the highest quality. Our risk control system includes rigorous testing throughout the production process, ensuring that all products meet the highest standards of quality before they reach our customers. We understand that product quality is important to our customers, and we are dedicated to providing only the best products and services. We are confident that our risk control system will ensure that all products meet the highest quality standards, and we look forward to continuing to provide our customers with the best products and services.

Quality Control System

We have been developing and applying an efficient integrated quality control system (CRM). We strictly follow the code of conduct and obey the regulations of CRM on a daily basis. Our company has developed a new-style quality control system, which includes three main pillars:


We keep our quality standards updated and always apply the newest and most strict industrial standards in our quality control system. In addition, we frequently do the test and make sure all the tests are done fairly under supervision.


We encourage staff to report risk issues and provide anonymous reporting channels like hotlines and mailboxes to protect our employees. Our Risk Control Department, isolated from any other departments, collaborates with third-party quality testing agency to guardian safety and quality.

-Multi firewalls

Three lines of defense are respectively established in the pre-production (raw material purchases) process, under-production process, and after-production process to identify and manage various quality issues.
