Support and suspension brackets, a collective term for brackets and hangers, play a crucial role in construction by bearing the weight of various components and their media, constraining and limiting the unreasonable displacement of building components, and controlling the vibration of components. They are essential for the safe operation of building facilities. Support and suspension brackets are mainly used in mechanical and electrical engineering facilities such as building water supply and drainage, fire protection, heating, ventilation, air conditioning, gas, thermal power, electricity, and communication, where thermal displacement occurs during operation and on the equipment installations.

Main types of support brackets include: door-type support brackets, root support brackets, accessory support brackets, seismic support brackets, load-bearing support brackets, etc.
