As embedded parts used in prefabricated wall panels and prefabricated stairs of prefabricated buildings, hanging nails and threaded steel sleeves are substitutes for each other, and the choices of various component factories are also different.Ceiling process introduction The process of the hanging nail is hot forging, the raw material is 20mn2A, the surface treatment is generally sandblasting, and some units with more stringent requirements will require galvanizing. The packaging is generally bagged. The delivery is delivered to the required location. The supporting products of the hanging nail include corrugated plastic, duckbill hanger, etc. It is recommended that you ask whether the process is hot forging or cold forging when purchasing, so as to avoid adverse effects on construction safety due to quality problems.Introduction of supporting products for hanging nails: rubber: made of rubber, hemispherical with a crack in the center, with a screw rod, which covers the small head of the hanging nail during construction to free up space for later lifting operations. The color is generally black, and moderate softness is the ideal effect. Too soft cannot be formed, and too hard will cause problems of difficulty in operation.
