The Application Of ETFE + PTFE Membrane Structure In Commercial Street, Guangzhou

The canopy project of Fenghuang Xintiandi Commercial Street is located in Conghua District, Guangzhou. The total construction area of the commercial street is about 76,000 square meters. The main structure of the canopy adopts a large-span spatial steel structure, and the upper part of the steel structure is covered with ETFE + PTFE membrane structure. The total expanded membrane area exceeds 3,000 square meters. The commercial street has two underground parking lots and a five-story above-ground urban commercial complex. It is adjacent to the G105 central corridor, enjoying obvious transportation location advantages. The shape of the canopy is like a phoenix spreading its wings to fly, echoing the name of the "Fenghuang Xintiandi" project, implying a bright future for the vigorous development of Conghua District.

ETFE membrane material has a service life of at least 25-35 years. After long-term on-site and laboratory tests, it is not affected by ultraviolet rays, air pollution or other forms of environmental weathering, and can maintain good performance. With the combination of ETFE membrane material and secondary steel structure, the building becomes more magnificent and beautiful. Similarly, PTFE membrane material is also a high-quality building membrane material. It is not affected by ultraviolet rays, air pollution, chemical corrosion and other factors, has a long service life, generally up to 20-30 years or more.

Under the design and construction of Zhejiang Marriott's professional team, the application of membrane materials has fully demonstrated its advantages. Its surface has been specially treated, with extremely strong self-cleaning property. In Guangzhou where there is abundant rain, rainwater can automatically wash the canopy during rainfall, easily taking away dust and dirt. Only a small amount of manual auxiliary cleaning is needed every year to keep the canopy always new. Compared with the frequent cleaning work of traditional building materials, membrane materials have greatly saved human and material resources, and the maintenance cost has been significantly reduced.

The canopy project of Fenghuang Xintiandi Commercial Street in Conghua, Guangzhou not only shows the strong advantages and technological innovation of membrane structure, but also reflects the important role of membrane structure in shaping the urban image and improving the urban quality. It is believed that in the future, membrane structure will be applied in more fields and make great contributions to urban construction and development.
