About us

Industrial Quality Since 2010

In 2010, we established our first diamond tool manufacturing plant in Shijiazhuang, serving as an OEM partner for several renowned brands in this industry. Since then, we have been offering a comprehensive selection of products for cutting, coring, polishing, grinding and shaping concrete, granite, marble, stone and glass.

15 Years of Innovation

Over the years, we have chosen only synthetic diamonds of the best grade, only raw materials of the highest standard, and only procedures under the strictest controls. This ensures that our products are produced to deliver superior performance on the toughest applications. We are fully committed to serving our customers with consistent high quality products in every possible way.

Strategic Role Expansion

In 2019, several reliable hardware manufacturers formed a regional Trade Cooperation Group. Saint-Deo was established as the integrated sales company representing all members, aiming to provide a one-stop solution for our retail and wholesale partners worldwide. Now, instead of dealing with multiple factories to procure assorted products, we handle that task — saving you significant time and effort.

Customer-Centric Relationship

We take pride in building long-term relationships by consistently listening closely, responding promptly, proposing tailored solutions, and delivering reliable service to each client. No matter your industry, our high-performance products cater to your specific needs.
