Abstract: Due to the rapid development of infrastructure projects in my country, the hidden dangers of construction safety have become a problem that cannot be ignored. At present, the casting process of cast steel fasteners used in building construction has attracted widespread attention. How to effectively improve the quality of construction steel fasteners has become a major issue in the application research of steel fasteners. This article briefl y analyzes the casting process of the new construction steel fasteners from the aspects of the difficulty in the implementation of the casting process of the construction steel fasteners and the optimization strategies in the implementation, in order to provide references for related research.
