Whilst the benefits of applying an industrialized building system (IBS) have been well recognized globally in the construction industry, the application of IBS is particularly limited in developing countries such as China, and quality is considered one of the key issues affecting its application. This paper identifies a number of the key quality factors which present barriers to the promotion of IBS within the context of the Chinese construction industry. These include key factors such as “Inaccurate design of the connecting points between core components”, “Lack of design norms and standards for IBS components”, “Lack of quality criteria for IBS components”, “Lack of production norms and standards for IBS components”, “Lack of quality management system in production process”, and “Lack of technical guidelines for the construction of IBS projects”. The data used for analysis are derived from a comprehensive practical survey. The validity of the data is examined by using a statistical method. The findings from the study provide valuable references for formulating effective measures to mitigate the negative effects of these quality factors on IBS application in China, thereby ensuring that practice of the IBS system can be further developed within the country.
