Prefabricated Building

　　Zhejiang Dadi Steel Structure Co., Ltd. is a state-level high-tech enterprise. The company insists in the joint research and development model of Production, Education, Research and Application, and has collaborated with more than 20 institutions of higher academies, design institutes, science & research institutes, such as Tongji University, Shanghai Academy of Construction Sciences, East China Architectural Design and Research Institute(ECADI), and Zhejiang Architectural Design and Research Institute, jointly dedicated on the research and development of prefabricated steel structure product systems and technologies .

　　The company has established a scientific talent cultivation, deployment and incentive mechanism, formed a rigorous, pragmatic and efficient work style, boldly pursued, and constantly challenged themselves. With the spirit of truth-seeking, enterprising and innovative, it has inspired batch after batch of "Dadi People", and has produced fruitful technological innovation achievements.

　　In 2018, Dadi Steel participated in the R&D and launched a high-performance, fully assembled, steel structure building product system-S-SYSTEM (S System for short), the first complete prefabricated steel structure residential system in the country that has passed the scientific and technological achievement evaluation of the Ministry of Housing and Urban-Rural Development. It was rated as a national construction industry scientific and technological achievement promotion project by the Ministry of Housing and Urban-Rural Development .

　　Oriented by Market Demand and Product Thinking as its principle, the S system integrates many elements in green buildings, passive buildings, healthy buildings and sustainable development. The innovation greatly improves the performance synergy between the molecular systems in the internal structure of the steel structure prefabricated building. Meanwhile, the S-System pays attention to the absorption and application of mature construction technology in the process of integration, which has well overcome many common process defects and common problems in the industry.

　　S-System covers four major building systems with assembly rate flexibly selected between 50% and 95%.The on-site construction period can be shortened by up to 40%, and the construction cost is basically the same as that of concrete prefabricated concrete buildings (PC) when the assembly rate is 50%. The higher assembly rate, the better concrete prefabricated buildings.

　　SYSTEM广泛适用于以标准层为主导的各类建筑需求，如多高层住宅、公寓、酒店、办公楼以及学校、医疗等，并在施工环保要求高、建设工期紧、内部空间易变等方面，相较PC类建筑具有明显的优势。

　　After professional development and accumulation in recent years, the company has accelerated the implementation of the innovation and development strategy. In accordance with the most advanced industry technical standards at home and abroad, the company has advanced to a higher level in the research and development of key technologies and important products, pioneering and innovating through independent innovation. Forge ahead with determination, new breakthroughs and accomplishments in the technical field of steel structure assembly have been made.

　　Since 2019, the provincial scientific research project: Research and Application of High-rise Prefabricated Steel Structure Residential Enclosure System, has been successfully completed, and more than ten inventions or utility model patents on A Modular Prefabricated Steel Structure System, have been authorized successively and published a number of related professional papers and participated in the compilation of the Technical Standard for Detachable Low-rise Prefabricated Steel Structure Buildings. The acquisition of new technologies, achievements and standards has witnessed the company's technological breakthroughs in steel structure assembly, presenting the strong technical support to the steel structure assembly in the lead of development of the industry.

　　In addition to the above achievements, there are four provincial-level scientific research projects under development, more than sixty authorized patents, seven enterprise-level construction methods, three standards, and dozens of professional papers published.
