In order to accelerate the development of prefabricated building structure, promote the deep integration of construction industry with informatization and industrialization, cultivate new energy of new industry, and promote the resolution of excess capacity, China will promote the development of prefabricated building structure, promote the transformation and upgrading of construction industry, and promote the high-quality development of construction industry.

Prefabricated building structure is a kind of steel structure building, which transfers a lot of field work in the traditional construction method to the factory, processes and manufactures prefabricated building components and accessories in the factory, transports them to the construction site, and installs them on site through reliable connection. At present, prefabricated building structure is gradually becoming a new trend of building reform and development. The advantages of prefabricated building structure are: effectively avoid waste of resources; effectively improve the quality of construction; reduce labor, ensure construction safety; effectively shorten the construction cycle; form a new economic growth point.

Hengli Petrochemical (Dalian) Co., Ltd. capped the steel structure of No.1 10 million T / a atmospheric and vacuum distillation unit and No.2 10 million T / a atmospheric and vacuum distillation unit, marking the successful completion of the installation of steel structure of 20 million T / a atmospheric and vacuum distillation unit. After the completion of the project, the project quality has been widely recognized by the society. In this steel structure production and installation project, all staff of Dalian Guangtong Steel Structure Co., Ltd. have made great contributions.

After years of development, Dalian Guangtong Steel Structure Co., Ltd. has become a large-scale enterprise with specialized operation, and has undertaken more than 100 large-scale construction projects, such as steel structure construction project of Toshiba (Dalian) Co., Ltd. and steel structure construction project of Haiqing industrial group in Dalian Development Zone. Dalian Guangtong Steel Structure Co., Ltd. actively responds to the call of the state and plays a leading role in promoting the development of prefabricated building structure and the transformation and upgrading of the construction industry.
