We believe that quality comes from design, whether it is the overall construction scheme or the quality of components, the quality of the entire project and products has been determined in the design stage of the scheme. Therefore, we attach great importance to quality control in the design stage, and we adhere to the principle of "it is better to spend more time in the early design stage than to repeatedly correct errors in the later stage of program implementation."

In view of the fact that design is in such an important position in the quality control process, Dinggong hired a very professional team. The team members are mainly divided into two types: design experts in construction and design experts in parts manufacturing. Through their concerted efforts, we are able to provide customers with almost perfect solutions.

Our products meet different standards. Firstly, the standards for architectural design must comply with the industry standards of the country where the project is located. Secondly, for the welding, stamping, casting, forging, and surface treatment of different parts, we need to comply with Chinese GB standards, and at the same time, we must also comply with more stringent international standards, such as SGS, Reach, etc.
The system certifications that the company has passed include: GB/T50430 Quality Management Specification Certification for Engineering Construction Enterprises, lSO9001 International Quality System Certification, ISO-14001 Environmental Management System Certification, ISO-45001 Occupational Health and Safety Management System Certification, EU CE Certification, ISO-3834 Welding Quality Certification, American AISC System Certification, American AWS Welder Certification, European Welder Certification, and Plus CWB Welding Certification, We can provide steel structure products and engineering services that meet various international standards according to customer requirements.

Our quality control runs through the whole project, from the project design, to the determination of the construction plan, to the selection of spare parts, the consideration of materials, the selection of surface treatment, and the various manufacturing links of spare parts. There is a professional team to control until the smooth delivery.

In terms of material selection for spare parts, Dinggong insists on using high-quality and durable materials. We firmly believe that using good materials can create more value for customers, and thus bring better product reputation to our company. We are not willing to use low-cost and low-quality materials.

For architectural decoration projects, in order to ensure smooth installation at the destination and provide customers with the most efficient assembly solution, we conduct trial assembly of some parts and nodes within the factory for important nodes and structures. Through trial assembly, many problems can be identified and something can be optimized; Of course, only in this way can we ensure the smooth transportation of components to the local site for assembly, and ultimately ensure that we can provide customers with the highest quality solutions.

Specialized laboratory testing equipment is essential for testing methods. We have a wide range of testing equipment, including 2D testers, metal tensile testing machines, RoHS testers, Rockwell hardness testers, salt spray testers, and high and low temperature testing machines.
In addition to our in-house testing laboratory, we also collaborate with third-party laboratories for load capacity testing, certification, and pre-shipment inspections, all to ensure more reliable and superior products.
