Hot dip galvanized embedded parts (prefabricated embedded parts) are components that are pre-installed (buried) in concealed works. They are components and fittings that are placed during structural casting and are used for overlapping when laying superstructure. After hot galvanizing surface treatment, antirust effect is achieved. In order to facilitate the installation and fixation of the foundation of external engineering equipment. Most embedded parts are made of metal. In the structure, bolts are embedded in the structure at one time, and the bolt threads set aside at the upper part are used to fix the components and play a role in connection and fixation. It is common to reserve bolts for equipment. According to the drawings for processing-measurement positioning-support bracket-put bolts, embedded parts and temporary fixed-retest and finally fixed.
