In the field of modern engineering, steel grating engineering has been widely used due to its advantages of light weight, simple construction and high strength, and has promoted modern engineering to achieve great breakthroughs in the construction of super high-rise buildings. With the increasing level of modern construction technology in my country, steel grating projects have begun to put forward higher requirements for the quality and performance of steel. At the same time, the higher cost of traditional steel welding has also become an important constraint on the development of steel grating projects. In this case, how to improve the quality and efficiency and reduce the cost of steel grating engineering has become a key issue.

          BIM technology, namely Building Information Modeling, is an important technology that assists the design and construction of architectural engineering based on digital three-dimensional technology. It constructs the engineering data model by integrating all the information of the construction project, which can form the data guidance for the whole process of the engineering construction, so that all professional parts of the engineering construction can use the building information model as a reference. In steel grating engineering, BIM technology can collect information on the production and processing of steel grating engineering, and then build a data model of the steel structure. At the same time, modern digital processing can be combined with BIM technology to operate equipment for digital processing of steel structures based on the data model constructed by BIM technology. Since BIM digital technology can continuously standardize, diversify, and correlate the data of BIM models according to requirements in the design and processing of steel structures, the construction of steel grating projects has more control links. At the same time, the visual model design and data deepening also provide favorable conditions for the staff to grind the feasibility of steel grating engineering design and structural performance parameters. It can be said that this technology has changed the traditional production and processing process, and also improved the level of informatization in the production and processing of steel grating engineering. Therefore, in modern steel grating engineering, the application of BIM digital technology has become an important trend, and it also affects the future direction of my country's engineering construction.
