Factory-Prefabricated Building Components

Factory-prefabricated building components are steel, wood, or concrete building components pre-made in factories or construction sites, characterized by strict quality control, high production efficiency, and a wide range of applications.

Strict Quality Control

The factory environment provides stable conditions for material processing and component fabrication. Taking wood as an example, operations such as uniform drying, anti-corrosion and insect-proof treatment, and surface protective coatings can be carried out. Precise cutting and tenoning are also possible, reducing on-site errors and ensuring the dimensional accuracy of components and the reliability of connection joints. Rural log cabin construction factories utilize CNC equipment and molds for production, enhancing the durability and safety of log cabins. For instance, using the vacuum-pressure impregnation method for anti-corrosion treatment can effectively extend the service life of log cabins.

High Production Efficiency

Components are produced to uniform specifications according to drawings, allowing workers to assemble them directly on-site, eliminating the need for on-site fabrication time. For example, building a structure used to take six months, but with prefabricated components, it can be topped out in three months. In rural log cabin construction, for a log cabin of about 100 square meters, the factory prefabrication period is approximately 15-20 days, and on-site installation takes only 7-10 days, significantly shorter than the construction period of several months to half a year for traditional brick-and-mortar structures.

Wide Range of Applications

Prefabricated components are used in multiple fields, including municipal bridges, subway stations, pumped-storage power stations, prefabricated building projects, highway expansions, and subway station entrances and exits. There are numerous specific cases. Shandong Huida Ruihe Building Materials Technology Co., Ltd. won the bid for the reinforced concrete prefabricated beam procurement project of the Municipal Construction Branch, employing intelligent equipment to manage the entire process. China Construction Eighth Engineering Bureau's Beijing Zhongjian·Xingguangli project used EMC prefabricated components in the main structural shear walls, earning the title of "Beijing Green and Safe Model Construction Site." Zhangjiajie Yuanda Residential Industry Co., Ltd. signed a contract with Hunan Changda Construction Group Co., Ltd. for the prefabricated component construction project of the Baojing Wine and Tourism Cultural Industrial Park (Phase II), adopting a prestressed support-free system. China Railway Fourth Engineering Bureau's Municipal Engineering Company undertook the Phase II project of the Phoenix City Resettlement Housing in Huaiyuan County, Anhui Province, employing a dual process of prefabricated construction + aluminum formwork construction, with an assembly rate of 50%. China Communications Construction (Guangzhou) Co., Ltd. constructed the Jia'an Station of Shenzhen Metro Line 20 Phase II using a fully prefabricated assembly method.
