The "6+N" product system deconstructs the prefabricated hardcover of the whole industry
Green, low-carbon, intelligent and safe, when traditional decoration accelerates the transformation in accordance with the guidance of high-quality development, the application demand of prefabricated hardcover in public buildings, commercial and residential fields is becoming more and more urgent.
Since 2017, Longfor has started the research and development of prefabricated technology from its own business needs, and with the breakthrough of core technology, the prefabricated decoration began to be widely implemented in the national Guanyu project in the following year; Since then, Longzhi Seiko has adhered to the four-step strategy of "R&D, boarding, adjustment, and promotion", extending the radius of prefabricated decoration to more complex scenes. As of the end of 2023, Longzhi Seiko's prefabricated hardcover products have covered residential, apartment, office, commercial, medical care, hotels and other formats, involving more than 500 projects, with a total construction volume of more than 5.5 million square meters, and has established good cooperative relations with central state-owned enterprises, AMCs, head technology companies, universities and other enterprises including China Great Wall Assets, China Rongtong, Tsinghua University, Xiaomi, Alibaba, Jingdong, Wanbang New Energy, etc.
Based on the precipitation of different scenarios, Longzhi Seiko further summarized the applicable scenarios of prefabricated hardcover. The newly released "6+N product system" divides the prefabricated hardcover of the whole business into two parts: "core module" and "optional module". Among them, the 6 core modules correspond to the ceiling system, wall system, partition wall system, ground system, intelligent system, and electromechanical system, which are suitable for all business scenarios; The "N" represents the optional modules in different business scenarios, such as integrated kitchen system, integrated bathroom system, integrated storage system, barrage system, building elevator system, door and window system, etc.
Longzhi Seiko uses a new matching logic to meet the needs of prefabricated hardcover in all formats. The "6+N" product system is not simply laid out, but starts with the end in mind, integrating the front-end design, downstream supply chain integration, and successful practices of sales and operation from a business perspective to provide customers with the best solutions.

On the one hand, based on Longfor's more than 30 years of experience in front-end development, construction and back-end operation, the "6+N" product system can reduce the "trial and error cost" of customers through standardized packaging, and continue to help improve the efficiency of the whole construction process. In Jingfa Longfor Guanyu Wuhan Derui Building Store, Longzhi Seiko completed the decoration and delivery of more than 200 apartments in only 40 days through the combination of green building materials and prefabricated technology, saving nearly half of the time compared with traditional construction methods, and achieving full lease 15 days after opening.
Comprehensive Laboratory Building, Department of Computer Science, Tsinghua University
On the other hand, on the basis of standardization, Longzhi Seiko has also been able to continue to meet the personalized needs of scenarios and enhance the technological competitiveness of the industry through self-research breakthroughs in core technologies and core patents. For example, in the hardcover process of the comprehensive laboratory building of the Department of Computer Science of Tsinghua University, out of higher requirements for fire performance, Longzhi Seiko innovatively adopted the process of metal keel and A-grade veneer, which greatly improved the overall flame retardant performance, and the project also won the gold medal of the "Great Wall Cup", the highest honor award for construction engineering quality in Beijing.
With the release of the "6+N" product system, Longzhi Seiko has found the direction of the optimal solution between quality, cost and efficiency.
With the blessing of digital technology, BIM is the non-traditional assembly of the base
With the rapid advancement of the transformation of traditional industries, with the support of technological progress and policies, the concept of prefabricated decoration to help "build a house like a car" has blossomed and borne fruit all over the country, and it also carries the task of digital transformation of the industry to the manufacturing industry.
For many years, digitalization has been the foundation of Longzhi Seiko, and BIM design is at the heart of it. In the past four years, Longfor has moved the rich products it has built over the past 30 years to the cloud, precipitating them into a spatial module database covering 8 levels and more than 100,000 modules. Based on the huge module library, Longfor has developed its own BIM collaboration platform, which assists manual review through a fully automated indicator system, and uses VR to conduct all-round simulation analysis before the project starts to ensure the high-quality presentation of the project.
Beijing Longfor Blue Ocean Engine Industrial Park
In Longfor Blue Ocean Engine Industrial Park, Longzhi Seiko transformed a 100,000-square-meter old auto parts city into a green, low-carbon, high-tech office space. During the renovation period, the project used 3D scanning technology to restore the building ontology information, build a "digital twin" virtual space, build a full BIM model of building + electromechanical + structure + curtain wall + landscape, and guide the prefabricated construction and installation according to the digital model. Based on the blessing of BIM technology, the project completed the whole process from construction to delivery in only 11 months, with an assembly rate of 75% and a change cost of more than 20 million yuan.
Relying on BIM technology, the traditional inefficient transformation process has been subverted, which has greatly improved the construction quality, and the application of VR technology has further reduced errors and omissions. In the digital space, Longzhi Seiko presents all details in advance through 1:1 complete restoration, combined with VR technology, and uses virtual reviews to find and modify problems in advance. By transferring the pain points of physical construction at the back-end to the front-end to solve, Longzhi Precision has reduced the overall design change rate to 1/10 of the original.
