Door Handle Hardware refers to the mechanical components used to operate a door, including the door handle, latch, lock, hinges, and other related components. Door handle hardware can be made of various materials, including metal, plastic, and wood, and comes in a range of styles, finishes, and designs to match different aesthetic preferences.

　　Some of the main types of door handle hardware include:

　　Lever handles: These are horizontal handles that are operated by pushing or pulling, and are commonly used for residential and commercial doors.

　　Knob handles: These are round or cylindrical handles that are operated by twisting, and are often used for interior doors.

　　Push-pull handles: These are rectangular handles that are operated by pushing or pulling, and are commonly used for commercial and industrial doors.

　　Deadbolts: These are locking mechanisms that provide additional security for doors, and are typically used in conjunction with a doorknob or lever handle.

　　Hinges: These are the joints that connect the door to the door frame and allow the door to swing open and closed.

　　Door handle hardware plays a crucial role in the functionality and security of doors, and it is important to choose hardware that is durable, reliable, and appropriate for the specific requirements of the door and its location.
